Volkswagen - Sensors - Cabrio :: CEL Came On For Code P0133 O2 Sensor Circuit Slow Response / Idle Rough
Got a 1996 Volkswagen Cabrio with around 125k miles. Recently the check engine light came on. Had the code pulled (P0133 02 Sensor Circuit Slow Response) and reset but it came back on shortly thereafter. I've also noticed that the car idles strangely, generally after it has warmed up a little bit. Basically it will idle rough and sound as though it might choke out but if you give it a little gas it goes back to a normal, even idle.
Right now it's getting around 20+ MPG average which seems a little low but I only purchased it 3 months ago so I don't have much to compare it against. One other thing I've noticed is that the plastic molding around where the gas nozzle goes in is cracked which makes it difficult to fill it up since it doesn't make a good seal unless you position the gas nozzle just right.
Any thoughts on whether either of these problems might be related to the weird idle? How hard is it to change the front 02 sensor?
Toyota - Corolla :: 2001 - P0133 Code Comes On
I've been getting a P0133 trouble code on my 2001 Toyota Corolla and am stumped as to what is causing it. I've ruled out the obvious stuff: I replaced the upstream O2 sensor and can vouch for the lack of exhaust leaks, since I replaced the entire exhaust system myself a few months back and checked again for leaks after getting the code a few weeks back. I haven't replaced the spark plugs yet (they're definitely overdue) or cleaned the MAF sensor (I've heard that these could be the culprits) and will probably do both this weekend.

I am getting a p0501 code (off my code reader) on my 2001 Elantra. I have already replaced the Speed sensor on top of the transaxle under the air filter. Driving into work today check engine light came back on and took to AutoZone. They are getting a P0501 code Sensor "A". They had no idea which sensor, sensor "A" was. I know there are 4 sensors on this car and have searched for other posts with no luck, all say replace speed sensor. Need to get this done to pass emissions.

I have a 2005 hyandai elantra with 176k miles. ck eng light came on with P0340 cam shaft positioning sensor. I replaced it and cleared code and ck eng light came back with same code. So as last resort took it to dealership who replaced the wire from sensor to ecu and told me i had a bad ecu. I replaced it with a used one from a semi-reputable salvage yard (i mean i have used them several times with no issues). The code came back almost instantly. Symptoms of the car starts good cold within a few minutes it is very slow to accelerate and i have noticed a severe loss of MPG. I have also checked timing because i changed the belt in this process.

I just had a ton of maintenance done on my 2003 Elantra. Spark plugs & wires, timing belt, drive belts, water pump, replaced coolant and replaced the transmission fluid. The spark plugs are NGK platinum as recommended in my handbook. As soon as the mechanic started the car after the tuneup, the engine light came on with a cam shaft sensor code. He said it went off on its own.
The engine light came back on when I started the car. There's also a major loss of power after coming to a stop. I have to floor it to get it to go anywhere above 20 mph after a stop.
The mechanic said that when he replaced my water pump the liquid splashed all over everything and he thinks he might have gotten something wet that shouldn't have gotten wet and that all will be fine after it dries.
Elantra XD (2001-06) :: 2003 - CEL Code / Bad Camshaft Position Sensor
I am new to Hyundai. I just picked up a 2003 Elantra and I'm doing a couple fixes to it. When I got it, the engine light was on and the code displayed said it had a bad camshaft position sensor. Is this a common issue with the car and is it an easy fix?
Also, I just installed new brake pads and a new battery. Now the battery and brake lights are on, although I know I didn't break anything. Could installing a new battery cause the two lights to come on?
Elantra XD (2001-06) :: 2002 - Cam Sensor Fault Code P0340
I recently took my car to the Hyundai dealer who told me that my engine light was from a bad cam sensor (Fault Code = P0340). I bought the sensor from the Hyundai parts dealer and replaced it myself. After having the code erased, the check engine light comes back on (with the same code) when I turn the car off and turn it back on, after driving it for a while (30 minutes or more).
View 5 RepliesElantra XD (2001-06) :: CEL Code P0501 For Vehicle Speed Sensor
So I am getting a CEL and p0501 (Vehicle Speed Sensor) code and don't quite know how to approach it.
Other forums/posts suggest that I check or replace the input and ouput sensors on the transmission, but from what I understand those are each a unique code, and the p0501 is for a sensor located on the transaxle. Is this the case?
I was under the impression that because my car did not have ABS that I did not have the latter sensor on the transaxle, only the input/output on the transmission. If that is the case, will replacing both eliminate the CEL/p0501?
Elantra XD (2001-06) :: 2003 - CEL Code P0113 / IAT Sensor High Input
So my mom recently bought a 2003 Elantra (75K miles, auto trans) and within a few days the CEL came on. She took it in to PepBoys and had them hook it to their scanner to get the codes out of it. The only code that came up was P0113 Intake Air Temp (IAT) Sensor high input. I've done a little research on the net but there is a lot of random info for this code out there. Is the IAT a separate sensor or is it combined in with the Mass Air Flow (MAF) sensor(if this car even has a MAF) or combined in with the MAP sensor? I've read on the net that it could be any of these 3, I think it's combined into the MAP.
I've also read that this code could be caused by a bad IAT, bad O2 sensor, an exhaust leak, bad wiring/ground(I checked the wiring/grounds visually and everything seems ok) or many other things. If it's as simple as replacing one of the sensors I can do that myself, I just don't want to go randomly buying things and either it be the wrong part or have it be the right part but not fix the problem. The car runs great, even with the CEL on. Yesterday when she stopped by my house I disconnected the battery for a couple minutes and reconnected it, started the car & no CEL. She drove the car for about 125-150 miles before the light came back on.
Elantra XD (2001-06) :: Engine Oil Temperature Sensor High Code P0198
2003 Hyundai Elantra, 1975cc engine, XD. P0198 Error Code.
I know this is the Engine Oil Temperature Sensor High code and I have seen indications this may mean high voltage on this sensor. My problem is I cannot locate this sensor on the engine. From what I have read this sensor is supposed to be on the driver's side of the engine on the head, rear side.
On my engine the head was replaced (unknown to me when I recently purchased the vehicle). From all indications this is not a CVVT engine. The air intake has a MAP sensor that is connected and appears to be functioning properly. The driver's side of the engine does have two coils but I can see no other wires from the wiring harness toward the rear of the head other than leads to the starter.
The cam sensor is located on the passenger side of the engine, rear side. I have found the oil pressure sensor and crankshaft sensor on the front side of the engine block toward the driver's side. I have found and engine temperature sensor on the driver,s side of the engine on a housing connected to a radiator hose.
Oddly enough there was an OCV hanging on the harness toward the front driver's side of the wiring harness. Adjacent to this plug is a second plug on a shorter lead that is not connected to anything. Both of these plugs have two leads but are shaped differently oval for the OCV and the other is rectangular. I am wondering if this rectangular plug is for the engine oil temperature sensor? What I cannot see is where the temperature sensor would screw into the head on the front driver's side (near this plug).
I went to NAPA today and they do not have an engine oil temperature sensor listed, but I was able to find one on line. I cannot find a connection point on the head that looks like the picture of the sensor on-line.
Honda - Cr-v :: 2005 - Fuel Air Sensor Replaced But Still Getting Codes P0133
I checked my engine codes after the engine light came on. They were P0133 and another indicating an A/F upstream sensor problem. I had it replaced by an independent mechanic. A few days after I had the same code. Mechanic went over it and thought it was loose wiring. A few days after codes P0133 and P0128 were generated. Now the light will come on every few days, will stay off for a few. Do I have to get my computer upgraded? Honda 05 CRV ...
View 2 RepliesSaturn - SL2 :: 1999 - Getting Code P0133 / SES Light Came On?
My 1999 Saturn SL2 recently showed the "Service Engine Soon" light. I brought it to Autozone for a code scan. They told me it is P0133, and could be due to a bad oxygen sensor. The only two pieces of info I have is that:
a) my car recently passed emission test mandated by my county, and the Service Engine Soon light comes on about a week AFTER the check
b) my car usually runs fine with no problem, only that my wife notes that it starts to "shake" when I drives over 65MPH or turns on cruise control. I have noticed a slight drop in fuel economy - from 22.5-24.5MPG to around 21MPG
Not sure if it is worth the money for the repair. If it were indeed the O2 sensor problem, what might happen if I don't replace it?
Ford Ranger / B-Series :: 1997 - CEL With Code P0133?
I have a 1997 Ford Ranger with a 4.0L 2WD. The check engine light just turned on with a code of p0133. I know that this is something with the bank 1 sensor 1. I tried doing some research and I think that it is on the passenger side before the cat converter. Now, I don't know what to do from there. How do I go about fixing this? What part do I need? How do I fix it?
View 1 RepliesGolf V R32 :: P000A Powertrain Code - Intake (A) Cam Position Sensor Slow Response
I've tried to do my due diligence searching on this (I've seen many posts but most have other codes).. I have the P000A code, reads as follows-- Intake (A) Cam Position Sensor Slow Response (powertrain).
I have no misfires, hesitation rough idle, nothing. I have 94k miles and I always done my oil changes @ 5k intervals and I have not had any prior engine maintenance done to the car....
I took my R32 to the local VW dealer today and they are saying they believe it might be the time chain tensioners. I am wonder if this could be a simple sensor issue since the car runs perfectly fine, I just get the engine light coming back on after 1 to 2 weeks of clearing the code. I have had this issue since January and I thought it might be the cold weather here in WI.
Subaru - Forester :: 2000 - CEL / Code Is P0133 Came On Randomly - Replace The Catalytic Converter
My 2000 Forester has 96,000 miles on it. A few months ago, the CEL came on. At first it would turn off every couple of days but would eventually pop back on. I first thought it was tied to putting gas in the car, now I think it was just a coincidence.
Over the past two months, I have replaced the catalytic converter with a aftermarket piece (done by a mom and pop muffler shop) and replaced the front o2 sensor three times. The first two times, I used Bosch sensors from an auto parts store and had the code cleared. After about 50 miles the CEL came back on. Just yesterday, I picked my car up from the dealership where they installed a Subaru fron o2. After about 30 miles, the light is back on again. Code is P0133 - heated oxygen sensor, bank 1 sensor 1, circuit slow response.
Now, the dealership is suggesting I need to replace the catalytic converter with a Subaru converter before they can source the issue.
Elantra XD (2001-06) :: 2004 - Acceleration Is Slow
Girlfriend just bought a used Elantra. She told me about an issue shes been having with the car and how it feels as though its towing a trailer. I drove it for a day and noticed a few things. Vehicle has 110,000 miles
1. No CEL
2. Tranny seems to NOT be slipping (Revs climb just as slow as Speed)
3. Car feels VERY heavy at times. Especially on a start up-hill
4. No sputtering/misfires
5. Shifts up and down smooth
What I've tried so far:
1. Replaced Spark Plugs
2. Sea-Foam
3. Cleaned MAF/Checked Airfilter
4. Removed and Inspected BOTH Catalytic Converters and both seem to be intact. *plan on doing a back-pressure test as soon as I get the gauge from my buddy*
5. Checked timing marks
I put 1/4 can of seafoam in crank case and plan on letting it "run-in" for 25 miles or so. I plan on doing an oil change tonight as well as make sure the brakes are not hanging up (I should have checked this first, thinking back...but hind-sight is always 20/20 ) .
Elantra XD (2001-06) :: Slow Speed Shifting From 2nd To 3rd Gear With CEL On
I have a 2001 Elantra gls which I bought a year ago. It had shifting problems from 2nd to 3rd gear with CEL on. I replaced the input and output speed sensors and connectors and fixed the problem to a point. It was still shifting a little hard even after a fluid change with SP111. I added 2 bottles of Lubeguard red and it has worked immensely almost to the point of no problems....except. At slow speed shifting like going into a store parking lot or on a freeway with stop and go traffic, it will shift hard from 2nd to 3rd (I think) maybe 1st to 2nd not sure. If accelerating at normal speed shifts fine. No cel and the tranny fluid is on the full mark, not overfilled. Would a wheel speed senso cause this or damaged clutch pacs maybe?.
View 4 RepliesElantra XD (2001-06) :: Slow To Accelerate - Multiple Error Codes
My '02 Elantra would have a hard time starting up in the winter right after I filled the gas to full. Usually I would have to give it some gas to startup. After that, it didn't have problems starting up until I filled it again. This was only in the winter.
About a month and a half ago, it became really slow to accelerate. Since the O2 sensor light had been on constantly for a long time I never bothered to check it. Soon the car became really slow to accelerate and would lunge forward in spurts. The error codes I got were P0133 and the O2 sensor. I replaced the spark plugs and the spark plug wires, and this seemed to do the trick. The check engine light went away, the car sped up nice and quick. Also at that time, I put in some fuel injector cleaner.
The a couple weeks ago, P0133 and P0420 came back. It seems like the car is using up more gas than it should. There is a very minimal sluggish response when I push the gas. I have a spare ignition coil, but trying to find what it could be more specifically before I swap out more parts willy nilly.
Elantra HD (2006-10) :: 2008 - Hard To Start / Code P2626 For O2 Sensor
I recently replaced the timing belt, water pump, tensioner, all accessory belts. Made sure timing marks were spot on, did the 2 revolutions of the engine by hand, tensioner pointer was still in window per instructions. I noticed right after the car seemed not as responsive, or zippy, but did start and run fine for 340 miles. Than out of nowhere, it became hard to start, acting like it was out of time, so I removed top timing cover, doubled checked, everything, I even went as far as advancing the timing belt 1 tooth, than rotating engine by hand, than trying to start the vehicle. It still acted the same way, so I tried retarding it 1 tooth back from the original position, still the same issue. So I reinstalled it back to the correct position with, white crank mark @ TDC, and cam pulley hole lined up with the red painted groove in the cylinder head. Installed tensioner per Gates instructions, attempted to start, after 3 or 4 10 second cranks car will start and purr like nothing is wrong, take it for a test drive approximately 1 mile, car starts bucking, came back home. Pulled codes, tells me P2626 for o2 sensor.
