SOURCE: check engine light on

You cannot reset the check engine light any other way than using a scan tool. Some auto parts stores will scan the vehicle for free then at least you will know the area of the fault.

SOURCE: How do I reset my check engine light myself

On most cars you can reset the check engine light by disconnecting the computer from it's power source. Disconnect one of the terminals on your battery. The negative terminal is usually suggested but I've never noticed a difference between the two. When you reconnect it and start it up, the light should be gone until the computer comes across another problem.

Chevy impala cuts off while driving

Check for any stored engine codes, this may give you an idea of any problems that may cause your complaint. Possible crank position sensor, cam position sensor or ignition module would cause a 'die in flight' situation.

My remote start is not working and the service engine light is on in my 09 chevy impala. what could the problem be?

The Factory remote start is disabled any time the check engine light is on. You'll need to find out what is causing the check engine light to come on by using a scan tool/code reader to read the codes stored in the computers memory.

You can buy a basic code reader for about $50 and do this yourself. You could buy a nice scan tool for $3,500 to $10,000 and again do this yourself.

You can also call your local auto parts store. Sometimes they will read codes for free. Please do not buy what every they think is the problem.

The last thing you can do is head into your local shop or dealer if under warranty and have them do the diagnostic test to see what the codes are and why they are being triggered. There is usually a set fee for this.

Some common things that come to mind that would cause a check engine light are, Low coolant temperature, loose/missing gas cap, Catalytic converter inefficiency, and maybe an O2 sensor code.

Good luck and let us know what codes you find.

I’m happy to assist further over the phone at
