Chevy Cavalier Engine Light Code For The Intake Temperature Sensor

Chevy cavalier LS.
2.2L Ecotech L4 134Ci vin F. TRAC OFF comes until I reset comp. Will stay off for about 10 miles then back on. Makes tranny run rough when light comes back on, yet smooth after resetting. Air temp sensor in plastic air inlet tube. I replaced ignition control module on top of valve cover,plugs and wires. Think fuel pumps now going. It has never been replaced to my knowledge.

Replaced air temp sensor in the air intake tube{right after the air filter.} I dont remember the actual code, but thats what it pulled up as. Reset comp,both check engine, and traction off come back on in 10 miles. Any help will be appreciated. Got laid off and need this car to get to my new job .Will send good tip after 1st check. Thanks

Question:
How to get the cars check engine Light to stay off{already replaced the sensor that the code pulls up on a OBD 2 diagnostic} and the traction control to stay off after resetting computer. Also is it possible to replace in-tank fuel pump with a in-line pump so I dont have to drop the tank? Will in-tank allow flow through? Only have access to floor jack and jack stands. Will be huge job that way.

Answer:
The intake air temperature sensor (IAT) is a common cause for your check engine light and causing the transmission shifting problems.

If the sensor did not fix it, then most likely one of the two wires is broken at the connector. The actual copper core breaks inside the colored insulation. You can check this by pulling on each wire one at a time. If the colored insulation stretches, the wire is broken inside and would need to be repaired.

Dont know of any conversion to put an inline fuel pump external to the tank. That would be a big waste of time anyway. Just fix it the right way and don't mess around with that stuff.

Question:
Hello. My 2003 chevy cavalier has the service vehicle light on. A wrench with the word service on it. Also the odometer does not show any number, it says ERROR. Any help would be great, thanks.

Answer:
Thanks for the tip/donation. These symptoms you are describing sound like a problem in the BCM (Body Control Module) The bcm sends the odometer reading to the dash cluster. Since it says 'error', the dash is not receiving the correct data.

The service vehicle light is on because of this problem. To be sure, you need to have the BCM scanned for codes. If you find B1000, then the BCM will need to be replaced. I will send you instructions on how to do this if you are going to do it yourself.

2002 chevy cavalier 2.2 SFI. Warning lights: temp gauge no working.
Repairs for this problem = replace the temp sensor Question: Temperature gauge is past the red mark like if it was over heating, so it does not work how do i fix it.

Answer:
If you are sure the car is not overheating and causing the temperature gauge to go into the red, there are a few other things you can check. It says you've replace the temperature sensor, which is a good start, but you also need to check the connector and wiring at the sensor as well.

You could have a bad terminal, or corrosion causing lack of signal to the gauge. You could also have a PCM that is bad and not allowing the signal to go through to the gauge on the dash. If all of that checks ok, then you probably need to have the gauge replaced. This would involve removing the instrument cluster and either sending it out for repair or buying a new one.
