Engine light is on


Its possible. It depends on what the actual code is and what the other O2 sensors are doing.
Trouble codes are only a guide for the mechanic to use in troubleshooting, not a command to replace a part.

I HAVE A 2001 CHEVY CAVALIER 84,675.00MILES . THE CHECK ENGINE LIGHT KEEPS COMING ON AND HAS BEEN CHECKED BY A MECHANIC SEVERAL TIMES. I REPLACED THE GAS CAP. THE CODES KEEP COMING UP A READING OF P4400. ...


P0440 is a large evap leak, so it should be pretty obviuos. first check if the vent valve is closing. then check when the purge valve is closed that its not leaking. He needs to COMMAND the vent valve closed and then smoke it. He should be able to command purge and close the vent valve, then turn off the purge and watch the vacuum level to know if its fixed or not.

I changed my spark plugs and afterwards the chech engine light came on. the jeep runs great. what can make that happen?


IT could be something such as a loose plug wire.The best advise I can give you is to take your jeep to your local auto parts store and have them pull the codes out of your on board computer.This will give you an area that you can concentrate on to make the necessary repairs to get your check engine light to go out.
