Chevrolet - Sparkplugs :: Check Engine Light On 1998 Malibu LS
After filling the gas tank yesterday, as I was on my way to work, the check engine light came on. For the last couple of days the temperatures outside have reached 118 degrees. I have checked the oil and coolant and have resealed the gas cap as well, yet the light still remains. The research I have done leads me to believe the problem may be the catalytic converter, but I'm wondering if there is any further troubleshooting I can do without heading to a mechanic.

I was recently in an accident deemed not my fault, my 250 was in perfect condition otherwise. After the accident when I received my car from the shop, they gave it back to me with the check engine light on and told me it was my O2 sensors. I ran a scan on them and the Bank 1 has low voltage, Bank 2 has high. What could be a cause of both of them to have voltage problems? The mechanics refused to believe the accident had anything to do with it, which is complete BS. I got hit on my passenger side, 11K in damage.

1998 Chevy C1500 4.3L V6 170,000 miles
My truck is stumbling and losing engine power sporadically. When this is happening I can usually drive it if I am real easy on the gas and slowly build up speed but if I mash it the engine will eventually just die completely. It has had this problem off and on for several years and now it's back with a vengeance. It always seemed to happen after a heavy rain but now I'm not sure.
Last week I had a mechanic look at the codes and he cleared them saying that once it happened again the code(s) that showed up would be a good indicator of the actual problem. The codes that were there were for a couple O2 sensors, catalytic converter and loss of vacuum I think. It happened again and his shop was closed so I got it read and cleared somewhere else and it was P0131 bank 1 sensor 1 and since I knew that one had come up before I went ahead and replaced it myself.
The next day the CEL came back on without any noticeable engine trouble. That was yesterday, this morning it rained and the problem is back and I went to get the code read and it was the P0420. There was also C0281 stop lamp circuit something or other that was new.
My gas mileage has stayed pretty good this whole time, always 15+mpg. Just wondering if my catalytic converter probably needs replaced, if I should replace other O2 sensors, or if this all might indicate something else in the engine.
Mazda - Tribute :: O2 Sensors Causing Check Engine Light To Come On
I have a 2001 Mazda Tribute with 141,000 miles. Recently, I've burned up both O2 sensors causing the check engine light to come on. My mechanic has replaced each and they've burned out again. The head gasket was replaced after that, to no avail. The check engine light continues to come on after being cleared in the computer. I have also noticed that on humid days, the car misfires on at least one cylinder., but any other time, it seems fine. What to check next? My mechanic is at a loss.

I have recently had about $1620 worth of work done on my 2000 4Runner because the check engine light came on and the code was P0420.. My invoice says they replaced the exhaust pipe assembly. Now 2 weeks later the light is back on with the same code...are the 02 sensors part of the "exhaust pipe assembly" or are they now going to tell me I need a bunch (2-4) 02 sensors replaced.

my 92 subaru check engine light has been on for months. I took it to my mostly-trusted mechanic. He hooked it up to the computer and the car did not give any codes. He reset the light, but it came right back on when started. I am wondering about the coolant temp sensor but I would expect that would give a code. Why won't a check engine light give a code?

Prius (Gen 2) :: Most Common Check Engine Light (CEL) Or DTC Codes?
I've had a 2005 Prius for almost 2 year and 50,000 miles now and had no problems. Recently I decided to do an inverter recall and them some "necessary" maintenance (TB, transaxle fluid, etc). How I have an intermittent CEL, P1112 (Intake air temp sensor) coming on every other day. Before I thought Autozone had another DTC detected (1121 It had something to do with a coolant stacked too high?)
What are the most common check engine light (CEL) or DTC codes and how to deal with them?

My '04 santa fe 3.5 v6 gls/lx, 79k miles, gas, auto, check light has just come on while I was driving a less than 10 mile journey. How can I check what is wrong. Do I need some sort of diagnostic code checker. Do any national outlets check it for free (Pep Boys or Auto Zone, etc).
Just 5 days ago (about 50 miles only) I had timing belt, water pump, plugs and leads replaced, brakes checked and lubes flushed; BUT not at above dealers. I would rather know what the code is saying before I go back to the shop who carried out the work.

My 98 chevy luminas service engine light came on after I got gas. I put vaseline around the threads to seal it and the light went out for 2 days and then came on again. I bought a new cap and the same thing happened, two days light out than back on. I took the car to Autozone and did a diagnostics test which came back with error message P0341, then took it a mechanic who ran his on diagnostics on it and he says the camshaft sensor needs changed. It is a semi expensive job for an older car and I want to be sure that that is the problem, plus the gas cap thing has me confused.
View 7 RepliesChevrolet - S-10 :: 1998 - Got PO453 And PO442 Codes?
so recently I purchased a 98 Chevy s10 with the check engine light on. Seemed like a good deal. Has a battery warning light constantly on and I have to turn and reset the ignition a few times each morning to get the engine to start but it ran relatively smoothly. I waited a day, then tried to reset the light by disconnecting the battery and cycling it. The light never cleared. Once my scanner came in the mail I ran it and came back with a PO453 (High pressure in EVAP) code.Looked it up, could be a variety of causes, and as I don't really have a place to tinker with it too much I started with the easy stuff. Checked gas cap, seems a bit weartherized and probably needs to be replaced. Got under the vehicle and had barely enough clearance to disconnect what I believe to be the FTP sensor .
Started the vehicle, stopped, then ran the code again, only this time it came up as a PO452 (EVAP pressure low). Reconnected the sensor, erased the codes and again the check engine light stayed on. Went to work today, code on. Got off and the check engine light was gone! Excitedly I ran the codes again when I parked at home and it still came up with PO452, but the Check Engine light is still off.
Lexus RX 2004-09 :: Misfiring And Check Engine Light Codes
The car was misfiring and the check engine light codes were all sensor coils were bad. Lexus told me that it was coil6 bad and they fixed it. I should have had no problems, I got a whole 2 miles and I misfired and engine light back on. I drove for a while and light went off and then misfired again. Before I bring it back in I was looking for some insight. I can't understand how it wasn't fixed right the first time but I don't want to go back and get a few thousand bill either. Could fixing one coil cause another to go bad.
