View 7 RepliesEngines - Honda - Lights - Accord :: 2001 - Check Engine Light Blinks And No Power
The check engine light will pop on an off rapid fire and the car will shake violently when you put it into drive or reverse for a minute, then the light goes off and its fine. then you'll be driving fine, and the light blinks on and off rapid fire again, and even if you have your foot to the floor, you cant get much power, then it kicks in and lurches into being fine again. I tried "tune up in a bottle" and it seems worse. I'm scared its transmission or something.. I took it and had it put on the diagnostic machine at autozone and they said there were no codes, which I find hard to believe since my check engine light is blinking on and off so much now. There doesn't seem to be any rhyme or reason to when it happens and when its fine. it will be fine for hours of driving, then in a small period of time, it will go through a whole bunch of spells of this happening.also: when this happens, the light that shows what gear you are in on the dash board goes black, then goes back on again when the check engine light goes off. What is going on with my car????!!!!!!

My check engine light comes on intermittently, fuel consumption normal. I have not had any noticeable performance issues. I took it to O'Rielly's for a scan but they could not establish a connection to get a readout. Is there a special scan tool needed? The on board Lan Monitor shows EMV codes below, are they meaningful in any way?

Ford F-150 (2009-2014) :: Check Engine Light Intermittently Comes And Goes
Purchased certified pre owned 2009 f150 may/2010 24,000 mile. The check engine light intermittently comes and goes. It seems that its either cold temperature or related to filling the gas tank. The first time it appeared I drove 100 mile then the truck sat over the weekend and went back off when started. The second time had serviced for the check light and the dealer diagnostic pin pointed P0304, P0305, P0300 and P0316 and replaced cyl 4&5 coils.
Prior to the replacement of the coils the truck averaged 18.2 mpg since the repair the mpg dropped to 17.6 and now at 17.2mpg. Had the truck in again and the light was on when I made the appointment but went back off when I went to the dealer. They said the reset the computer. The light twice has since went on and then back off after a couple days. The only observation is that the outside temperature on both occurrences has been below freezing and that I had filled up the tank.
Dakota :: 2000 V8 - Check Gauges Light Comes On Intermittently / Engine Dies
2000 Dakota, 4.7 V8 ... The 'CHECK GAUGES' light comes on intermittently. As soon as it comes on, the voltmeter gauge drops to zero (it is a brand new battery); the temperature gauge does flip flops; the truck dies right now. Walk home and come back later, and it starts up again. When you get home, you sure don't feel secure in taking it on the road again. The shop checked it and of course there was nothing wrong when they had it Where do I start the troubleshoot? Is it computer or?
View 1 RepliesFord - Escape :: 2003 - Check Engine Light Blinking Intermittently
Intermittently blinking check engine light in a 2003(?) Ford Escape. I received a call from my fiance, who's about 45 minutes into a two hour drive. On the interstate, her check engine light started blinking, so she pulls off the interstate to a gas station (the light was blinking for maybe five minutes before she could stop, according to her). After she was off the interstate, but before she had turned the engine off, the blinking stopped.
She called me, and I looked up and directed her to an AutoZone about a half mile from where she was. Told her to drive there, and have them to try to read any codes from the engine. She drives over, engine light stays off the entire time. They hook up the reader, and there aren't any codes. My question is, if the check engine light stops blinking, and there aren't any codes for the reader, is the car safe to drive, or will she destroy the cat if she keeps going? Also, it's raining, if that matters for any reason.
Ford - F150 :: Check Engine Light Intermittently On Due To Overheated O2 Sensor
Have 1994 F150 with 5.0L engine. Check engine light, intermittent on due to overheated O2 sensor. Replace sensor, light goes off. The sensor will last longer in cold weather but will fail with same code. Is the overheating due to an electrical problem from the ECU or ambient tempreture. Would like to sell truck but don't want to hand the buyer a dozen O2 sensors.
View 3 RepliesAccent LC (2000-05) :: 2004 - Check Engine Light Coming On Intermittently
I have a 2004 Accent GS. It is an automatic. I have had it for almost a year.
In early November, the check engine light came on when the temperature dropped drastically and it went off when it warmed up a bit about 3 days later. Since then it seems to come on randomly and stay on for a few days then go off (usually around once-twice a month). Then in late December I noticed that the car had trouble starting after I refueled it, the first two times I though it was because I had let the fuel get down too much. Now every time I fuel up it does this. But just the first time turning on the car and no other time after that.
The check engine light had not come on again for almost a month, and then about a week ago it came on again. I double checked all the fluids and the gas cap but that's about as far as my knowledge of cars goes. When the light has come on I have not really noticed any handling differences. However since I need to put the car through an inspection very soon it is now concerning me a bit more. What could be causing the check engine light to go on and off?
Audi - A6 :: 2004 - Check Engine Light Intermittently Flashing / Misfire On Cylinder 2 And 5
I have a 2004 Audi A6 wagon that has an intermittently flashing check engine light. I took it to the dealership to have the codes read and they told me that they got codes for Cylinder 2 and Cylinder 5 misfires. Additionally they got a code saying the Engine Coolant Temperature Sender was electronically faulty. What is this part and what does it do? Is it essential to fix it immediately?
The dealership recommended changing the spark plugs and the air filters for the cylinder misfire issue. We are also talking about replacing the timing belt since the car has 105k miles on it. I know there are several other parts that are replaced during the timing belt replacement (like the water pump, thermostat, oil seals, etc). Is it essential to replace these items if there is no immediate need to do so?
Honda - Grandcherokee :: Check Engine Gas Cap Code On 2001 Jeep
My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001
View 17 RepliesHonda - Cr-v :: 2001 - Check Engine Came On / Cylinder Misfire Code
I have a 2001 Honda CRV with about 140,000 miles. It is an upstate NY car, so has seen its share of salt and rough winter driving, has a little bit of rust.
I recently brought it in for repairs because it was overheating. It was over the holiday weekend and I had a job interview to get to so I brought it a chain, which was the only open mechanic I could find. They told me there was a coolant leak and replaced the radiator.
The next day, the check engine came on. Cylinder misfire code. I took it back to them and they wouldn't give me a straight answer on what was going on but insist they told me that would happen and it needed more repairs which I had apparently refused. They told me it's probably the spark plugs/wires are old but maybe there's more damage, but basically that they didn't want to deal with it.
So I brought the car to my regular guy. He says, yeah it needs a tune-up. So he replaces the spark plugs and wires etc and gives it back. I drove it for a day and the light came back on. So I brought it back to him again and he refused to do anything. Wouldn't give me some possible causes or explanations, just says come pick it up. Didn't say stop driving it, take it to a dealer, he just reset the check engine light and said its probably fine.
The next time I drove the car, while it was warming up the check engine light was flashing. By the time the engine was warm the light had stopped flashing and was on.
Subaru - Legacy :: Raw Fuel Smell Out Of Tail Pipe / Check Engine Light Intermittently Comes On
When I turn the key all the way over, I hear only one click, and no engine sound. Playing with park or neutral positions do nothing. Battery and connections are good. I am getting a raw fuel smell out of the tail pipe after it finally starts. The check engine light intermittently comes on, by now it is mostly on.
My guesses are: fuel pump/relay problems, starter/connection problems.
Honda - Accord :: Check Engine Light On - Engine Surging / Running Very Rough
My mechanic tells me I need the intake manifold gasket replaced (check engine light on, engine surging, running very rough). How much damage can I do to the car by doing this repair myself and screwing it up? I've done lots of repairs on my car before -- brake pads, rotors, replace oil pan. I also have a copy of the manufacturer's shop manual.
View 2 RepliesHonda - Accord :: 1991 - Odometer Stopped Working - S Light Flashes - Check Engine Light Sometimes?
I am a grad student hoping my car will hang in there till graduation next year. I have about 227,000 miles on my Honda Accord Wagon and recently the odometer stopped working, S light started flashing, and the check engine light came on. This only happens sometimes, and the check engine light does not always come on when the S light flashes and odometer stops working. I've continued driving the car to see what happens and so far, no problems have come up. I have driven another 1000 miles and am hoping I can just ignore the problem and continue driving the vehicle since I am not in a position to fix it or get a new car.
Recently I passed my California emissions test and she seems to be running smooth. Any thoughts or warnings as to why sometimes these signals happen?
I have to drive with GPS on all the time to know my speed, but other than that I feel OK.
Santa FE SM (2001-06) :: Engine Light That Comes On And Off Intermittently
I have a 2006 Santa Fe 2.7L that has the engine light that comes on and off intermittently. I went to the Auto Part Store and they read the computer and said it was O2 Sensor Bank 2 Sensor 1. I believe that is the upstream sensor on the radiator side (top sensor before the converter) but am not 100% sure.
Also, I am confused when they say left side and right side of the engine as the engine is transfixed. Is left side the driver's side of the engine or is it firewall side? Where the left and right sides are.
For example, the computer readout said O2 sensor upstream right but the tech said bank 2. are they one and the same?
Honda - Odyssey :: 2001 - Recurring Check Engine Code Cat Converter P0420
I have a 2001 Honda Odyssey with 90000 miles. Lat last year around Oct/Nov time frame, check engine light came on. I took my vehicle to a local Auto Zone store and they scanned the code and told me it was P0420 - bad catalytic converter.
I replaced the cat converter with an after market model, however after 3/4 months (after driving 2000 to 3000 miles), check engine light came on with the same code. The mechanic changed the cat converter and put a new (after market model). Again after 3/4 months (2000 to 3000 miles) check engine light came on again. And this time the mechanic replaced the cat converter and also oxygen sensor. Now after 4 months or so the check engine light is on the vehicle again.
The mechanic is now saying that the problem is not with the cat converter and he is saying there is a lot of abnormal deposit on the vehicle. When he scanned again he found another issue that read something like "high voltage" and this time the guy thought may be due to short circuit (per code) the fuel injector is sending high volume of fuel and this is causing excessive fuel to go into the cylinder and hence high volume of emission. I replaced the fuse box again and after another 100 miles or, the problem is reappearing.

View 2 RepliesHonda - Accord :: Check Engine Light Flashed 3x Then Off
My question: was there some some OBD code or light I should have expected (that didn't show)? What did the flashing Check Engine Light mean?
At 10:30pm last night, I picked my wife and bro-in-law up from the Logan airport, and on the way to drop BIL at his house, I saw a brief whisp of steam/smoke rise from the passenger side hood/wheel-well when idling at a top-light. I exclaimed that the car was smoking, but BOTH my wife and BIL insisted that we had been stopped over a steam grate. (In 70 degree weather? I puzzled, but since BOTH said that had been the case...).
A few minutes later, the check-engine light flashed (three times, I think) and then went off. I drive with an OBD ScanTool attached on the dash, so I immediately switched it to scan the codes, but it reported "clear" / no codes! Either immediately before or immediately after, the car lost accelerating power for 1 or 2 seconds (at most), but then resumed normal driving. No other dash lights were on, though I did not look at the temp gauge.
I am a former chef and professional cook, and have a VERY sensitive sense of smell-- there was NONE; I watched attentively, and the absence of further smoke/steam seemed to support the unseasonal steam-grate hypothesis. I had also picked up the car within the last 24 hours from THE HONDA DEALERSHIP, who I had asked to look everything over to ensure another 6 months of problem-free driving. (I rejected their offer of a $249.00 "triple flush" of transmission, brakes, and pwr steering.) We have otherwise had zero problems with the transmission or cooling-- the car is old, but maintained reasonably well and driven less that 5000 mi / year. Boston driving, but not aggressive or 19 years old!
No further thought, as all seemed okay except for the brief "blip", and pregnant wife, brother-in-law, two dogs, and I all wanted to get home.Drove the 2ish miles to our apartment, with no further blips. At a stoplight about 3 blocks from home, a LOT of smoke/steam started coming out from the hood. Still no lights or OBD codes! At that point, I pulled over within 5 seconds, and noticed that the temp was pinned or nearly so (If there is supposed to be a light on the gauges, I had it all the way dimmed). Looking under the hood, the spray pattern on the hood insulator made it easy to find the split in one of the hoses connected just under the distributor (about 1.25in OD; I'm guessing coolant or transmission, based on the symptoms??).
While waiting for a tow-truck (since I wasn't even sure if it would do any damage to drive the remaining blocks to my driveway), and after things had a chance to cool a bit, my wife restarted the engine for a second so I could check if any additional fluid came out of that split, but none did. Once the temp was back down towards the low end in 20ish minutes, I drove the car about one block so I could stop blocking traffic-- it drove fine, and the temp didn't visibly rise in that 200 yards. Still, the CEL was not on (or flashing) during startup or while running, and there were NO OBD CODES.
