Ford Excursion :: 2001 V8 - Code P1131 / Lack Of Upstream Heated Oxygen Sensor Switch
I have a 2001 Exrursion 5.4L V8. The code P1131 comes up and it says "Lack of upstream heated oxygen sensor switch - sensor indicates lean - bank #1". I hear it could be the sensor that is bad or there is a vacuum leak. It runs like a champ, no spitting, no sputtering, no missing, no ruff idle. What do I need to do to fix it or where do I need to start looking?

I'm trying to locate the MAF sensor on my 2001 LC accent. I can see the air cleaner box, the tube which T's off to the surge tank, and then it goes straight into the throttle body. On the hmaservice website, it shows a MAF sensor between the air cleaner box and the surge tank (or "resonator"). I don't have that! There's concertina tube going straight from the throttle body to the air cleaner box (with T off). Am I just missing a part?? There don't *seem* to be any unused harness connectors lying idly around the place!

I have a 01 Hyundai Accent, 1.5L, stick shift. My CEL came on and I had it read. Mechanic told me it was P1128 (Fuel Lean) or something like that. Looked it up on line and everything said to check for air leaks and then look at the MAF Sensor. I checked and saw no leaks. Took out MAF Sensor and cleaned it with MAF Cleaner. Disco'd battery to reset computer. CEL went out for maybe 30 minutes and then back on. Didn't do anything with it for about 4 months, now car stutters sometimes.
So, I finally broke down and bought MAF Sensor and replaced myself. Disco'd battery to reset computer. Started up and engine was not smooth at first(30 seconds) then smoothed up. But CEL still on. Drove home (25 minutes) and checked again this morning. CEL is off! Only problem is that the car stutters a little at acceleration. Smooth when at cruising RPM and speed. Just stutters a little at start of acceleration and when switching gears until at cruising speed. Is this going to go away? Is the computer just getting set up after changing MAF Sensor?
Celica :: Downstream O2 Sensor In Upstream Spot - No Power?
I actually found headers for my 5sfe and I took them cleaned them up real well and put them on.
The problem I am having is that the o2 sensor space on the headers is for the threaded style sensor and the upstream that comes stock is the bolted on style although the downstream does have the threads.
Can I take the downstream o2 sensor and put it in the slot and since I have put on headers it takes out the cat will this make the car run like crap? also I have tried to take it down the street with just the headers and I had almost no power.
would this be caused by the downstream o2 sensor in the upstream spot and no exhaust other than the headers?

View 5 RepliesCamry :: 2004 - CEL Code For Upstream O2 Sensor / Idles Very Rough
I just bought an 04 camry 4 cylinder. It was running perfect when I got it but the moment we got home it threw a CEL. The code was for an upstream o2 sensor, however I did a resistance test and the heater circuit is fine. I did a voltage test on the blue and white wires and I got 3.3v and 2.9v. I don't remember which wire gave me which voltage at the moment. I would like to know if this data is a good thing or if it's broken. I do not have any data to go off of, and I couldn't find the factory service manual online. Its also worth mentioning that it idles very rough and the catalytic converter is giving a rotten egg smell but not all the time. When neither of these things happen the CEL goes away. I do not want to start throwing parts at it.
View 1 RepliesCamry :: 2006 - Check Engine Light Came On - Code P0032 For Upstream O2 Sensor
This issue pertains to a 2006 Camry LE 4-cyl.
My check engine light came on - code P0032 (upstream O2 sensor). I bought a new sensor from O'Reilly Auto Parts. After installing the new sensor, the car would jerk while accelerating. This continued to happen until roughly 30 miles or so when the engine light came back on and the jerking stopped! I re-scanned the car and it showed the same error - P0032. I then erased the code, and the jerking issue resumed.
I assumed this was caused by a faulty O2 sensor. I returned and got another one. Same issue.
Is this the result of not getting an OEM sensor from the dealer? Or is there something else I should be worried about?
Ford Ranger / B-Series :: 1998 - Code P1405 - DPFE Sensor Circuit Upstream Hose
I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)
Prius V :: Socket Turns Loose On Spark Plug Head
I'm trying to replace the spark plugs of my 2006 Prius, but the deep well 5/8 socket attached to a 2 in extender just turns loose, as if it does not fit in the top of the spark plug. I tried also 3/4 and 13/16 but those don't even fit in the spark plug well. I tried in another spark plug to the same result. Problem to replace to spark plugs?

Girlfriend went to start her car on a nice cold day, and said it wouldn't turn over. so after taking her to work, i tried to see what the issue was . . . and the key wont move. the steering wheel is loose, i used the transmission override to move the stick back and forth a few times. still no go.
Did the hammer tap on the key, and used electronics cleaner on the switch in case something was stuck.
Oddity was, the door ajar chimes come on without the key inserted. So am I chasing electrical gremlins or what? the car is a base model without keyless entry.
Accent LC (2000-05) :: Bushing Loose - Rear Control Arm Removal
Alright, after taking everything off and replacing all the joints/bushings, I am left with the control arm. (it hasn't been easy either)
I am at the control arm (Passenger side) and i got the rear bushing loose. I managed to brake the front one loose, with a lot of force, but it spins. I see in HMA that it has a bolt, or so it appears, but how on earth do you get to that?

my 2002 Hyundai accent with 1.6 engine and the manual transmission has a problem in that where the axle shaft goes into the transmission is very loose. the problem is in the transmission, not the axel. Is there a bearing in the transmission for this. Or is there something else that could do it.

I went to emissions test my 2002 Accent, 1.5L 5spd, and failed because of a faulty engine coolant sensor. Problem is, I can't find it anywhere! Worse, I can't find anything online either. I have my second child on the way and need to sell the car and this is the only thing preventing me to sell. Is it worth it to replace myself or to take to a shop and have them do it.
View 6 RepliesAccent LC (2000-05) :: Recurring Cam Sensor Input Low Code
About 3 weeks ago, I purchased a 2001 Accent GL 4dr 5spd from a friend of mine. A few days later, the CEL came on. I went to O'Reilly and got the code pulled, it was for a cam sensor input LOW. I replaced the sensor and was on my way.
Yesterday after starting the car for the first time for a few days (I wasn't driving because it needed a clutch), the light came on. Has it gone bad again or is something causing the signal to be low? Maybe a low output on the alternator or low battery? The interior lights dim slightly when the brake pedal is applied while the car is running.
Accent LC (2000-05) :: How To Reset A Throttle Position Sensor
I was reading the car's settings using the Torque app and an OBDII bluetooth dongle and I realize that at WOT the ECU is only seeing 85% from the TPS. O know on some vehicles there is an actual procedure like turn the key forward, hold the gas pedal at WOT, turn the key all the way forward w/o starting while pulling the turn signal stalk down or something crazy like that to force the ECU to re-measure while you keep the gas pedal pinned to the floor. I know on other cars when it doesn't read a full 100% you miss out on a small amount of power and MPG so if it's an easy procedure with these cars I'd like to reset it. I did some searching but mostly came up with info on how to replace it and a few related subjects but noting on this specifically for this car specifically.
View 2 RepliesAccent LC (2000-05) :: Camshaft Position Sensor Code P0342
So my little car.....driving home from jersey (about an hour and a half) and within the last 2 miles I notice the car just shut off. Not any electronics just the motor. Pulled over and tried to start it an it just cranks prolly no fuel or spark. happened to have my obdII scanner with me. It says camshaft position sensor(po342). Only code in there. Sounds simple enough. Got a new one and put it in. Just cranks. Plugs and wires were done about 3 months ago and I drive about 40 miles a day 5 days a week. I did the timing belt last spring so I opened that back up to make sure the timing hadn't jumped for some stupid reason. It's perfect. Noticed now after doing all of that there is some (a little) oil in the throttle body. I know about blow by and don't think I should have that much at 113k but who knows.
