It could be a # of things, You need to have the engine scaned with a engine scanner.
Some parts stores will do that for free.
An engine cylinder misfire has been detected
Go to AutoZone and ask one of the fellas to come out and "check your check engine light code". They will be able to tell you what the problem code is, as well as re-set your check engine light.
NO!!!
What year is your car? Did you mean the CHECK ENGINE light? The battery gauge?
If the check engine light is on for your 1991 Toyota Cressida, that makes that some repairs need to be made to the engine. Taking the car to a certified mechanic to perform a diagnostic test can confirm if there is any issues with the engine.
Your question makes no sense at all, at least not in the Check Engine Light category which you posted it in.
No, a loose gas cap can cause the check engine light to come on but not the low fuel light.
Idle control valve - a part that costs about $200.
Disconnect the negative battery cable for a couple of minutes, then reconnect. This will erase the codes in the computer that makes the CHECK ENGINE light come on. If everything is okay, the CHECK ENGINE will stay off. Tried exactly that advice on my 2001 Camry....and it worked like a charm!!!
Have vehicle scanned to determine the problem - most auto parts stores do this free
The check engine light is on when the engine computer has detected a malfunction and set a code. There are pages of possible causes. You need to have the system checked with a scan tool or code reader to have a starting point.
your cat converter burns unburn gass sent out of the truck in the converter then uses it in the engine it saves you gass and makes your truck not smell like its from the 40's Also it is likely the check engine light will come on and stay on. It is also illegal to remove the cat.
