I had a check engine light pop up and I went and got it checked out. Comes to be its a IAT sensor or bad connection with this sensor. I change the sensor and made sure the wires on it is all good. The question is, I still have the check engine light up, does the code need to be deleted? And what happens if the code gets deleted and problem is not fixed?
View 3 RepliesI cleaned my k&n air filter on my 02 passat 1.8 turbo let it dry oiled it very lightly, and 50 miles later I get a check engine light on, pulled the code 16486 and it says Mass or Volume Air Flow Circ Low Input. Cleared the code put a frame in until I can get it filter. Why that would throw me that code, k&n oil gumming up my sensor??

View 4 RepliesThe check engine light came on in my 05 so took my local shop and they checked the code and said it was the Idle Sensor. They were not able to make the repair. Since then the light went off for a few days then came back on. I now notice the gas motor does not turn off when I stop at a traffic light.

View 19 RepliesI recently purchased a 3.5 V6 Santa fe. The Check engine light keeps going on. I took it to a few shops and I am getting the same code. It is the O2 sensor in bank one. (I think the the code was po170.) The light keeps going on and off. All I can find are the same problems with different Santa Fe engines (2.7, etc. )... My SUV has 100,050 miles on it.
View 1 RepliesI have an 04 gx with a check engine light on I had the code read at auto zone. That tells me o2 sensor bank 2 sensor 1. I have already changed the sensor they said it was and still have the code. What is the correct location of this sensor?
View 2 RepliesMy 2009 Camry check engine light is on. Dealer said the two O2 sensor both are dead and need to replace. After dealer reset the check engine light I have driven two days for 50 miles and the check engine light doesn't come back. If the O2 sensor is bad how long does it take for check engine light on again? Is it possible the check engine report on by mistake since two O2 sensors got bad at the exact same time is really rare.
View 13 RepliesOk so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.

View 11 Replies2004 XC90 T6. Local Volvo dealer (Bangkok at the time) said my check engine light was due to the O2 sensors going bad. I changed out the one under the car, then my wife threw out (accident) the other so I didn't change the one accessible from the hood. The check engine light went away so I figured that was that.
Fast forward a year later, I buy an Autel Maxiscan MS509 and now I'm getting check engine code P0455 which is probably the O2 sensors I didn't replace. Other than deductive reasoning, is there some way to look at the data on my OBD reader to confirm which O2 sensor is bad?
Wife has a 08 solara 2.4 auto. Check engine light is on for bad knock sensor in bank 1. Now car is not pulling itself, it takes off fine then shifts and falls on its face, I think its missing 2nd and going to 3rd. It is also not shifting into 5th so its staying in 4th and using a lot of gas. I tried manually shifting but it still goes to 3rd and will not go to 5th. I have been told this knock sensor could be causing it all. Cant clear code, I hit clear but nothing happens. We don't have a lot of money to pay the Toyota dealer to fix it and I can do all the work but they wont even show me where the knock sensor is.
View 5 Replieslast fall, the check engine light came on- Autozone states the knock sensor is bad. At the same time, odometer/cruise would work off and on. Now as months have gone by, the odometer RARELY works. Could all the electrical issues be connected? Is odometer controlled by Speed Sensor on the transmission or somewhere else?

View 2 RepliesSo this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

I have a 2012 hyundai accent. The check engine light came on. The code read knock sensor. Before I could get it into a shop, it went off. It didn't come back for 11 months. When it did come back, the same code was read. Again, it went off the following day before it could be looked at and hasn't been seen since. The shop says that even though there is a history code, it would be hard to diagnose since it isn't an active code. I noticed absolutely no difference in performance when the code was active. Both times it went on, the car was idling for several minutes with the ac on, and it came on as i accelerated onto a highway immediately afterwards. However, it has idled like that many other times without the light coming on as well.
View 11 RepliesCheck engine light came on about 2 weeks ago on my 2013 elantra gls. I went to auto zone to get it checked and they ran a p2096, which is what I had almost a year ago. That was fixed by dealer software update. So, I thought that was what needed to be done, headed to the closest Hyundai and they found p2096 and p2196. They replaced the o2 sensor bank 1, under warranty.
However, the next day the check engine light came on, less than 24 hours. Brought it back to the dealer, they said everything was within the correct "parameters" and said the light shouldn't come back on. On the way to work this morning, the check engine light came on, when the car was in the exact same spot it was yesterday.
I'm thinking the computer doesn't recognize the repair and needs to cycle a few times but I don't know. I'm so tired of going to the dealership because they are obviously missing something if the light is still on.
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 RepliesThe "check engine soon" light appeared yesterday on this nice running 1997 van with 167K. An auto parts store code check indicated a problem with the oxygen sensor. Is this something I can replace myself--a lightweight shade tree mechanic? I never seem to have any luck asking questions on the Mopar website.
