Service engine soon light comes on and gas guage does not work


IT SOUNDS LIKE YOU HAVE 2 UNRELATED PROBLEMS. THE CHECK ENGINE LIGHT 9 OT OF 10 TIMES IS DUE TO AN O2 SENSOR, ITS PART OF YOUR SMOG EQUIPMENT. IF YOU DRIVE RELATIVELY SHORT DISTANCES ALL THE TIME THE OXYGEN SENSORS WILL GET PLUGGED CAUSING THE LIGHT TO COME ON, REPLACING THE OXYGEN SENSORS ISNT A BIG DEAL. NOW FOR THE GAS GUAGE NOT WORKING, IT COULD BE A FEW THINGS, FIRST CHECK YOUR FUSES, IF THEY ARE OK, IT COULD BE A RELAY, A BAD GUAGE OR JUST A LOOSE WIRE TO THE GUAGE,OR THE SENDING UNIT FROM THE TANK TO THE GUAGE. BUT MOST LIKELY ITS PROBABLY A SENSOR THAT HAS GONE BAD.

2005 Chevy Impala LS. Will a bad upper intake cause an engine light to come on. I've been told I need a new Upper intake but currently have no engine light on.


the check engine light comes on when there is an issue with a sensor/sending unit/system/or something the pcm controls. The check engine light does not come on when there is a mechanical issue such as a bad lower intake gasket.

There are times when a mechanical problem can cause a sensor to read incorrectly and cause the check engine light to come on.

I just changed my brakes yesterday and everything was fine, but today i drove the car for 80 miles and the abs lights came on.


check the fluid again,, if the brake pedal feels spongy at all,, you have air in the lines still, if so , bleed the brakes,, unhook the battery to clear the light, and try again

I need to reset check engine dash light in 2004 deville. dealer has told me what is going on and i choose not to repair at this time. how do i make the check engine light in dash


If the check engine light is on, one of the sensors on the engine are not sending the computer the right signal. And most of the time the sensor is bad. And that is probably what is wrong with your car. So until the sensor is replaced, then you can not reset the check engine light.

NO THE CHECK ENGINE LIGHT COMES ON WHEN YOUR ENGINE CAN'T READ A SENSOR ANYMORE GO TO AUTOZONE THEY PROVIDE A FREE SCAN OF YOUR CAR AND WILL TELL YOU WHICH SENSOR HAS FAILED OR WHAT SYSTEM IS NOT IN WORKING ORDER

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

1993 Camry Check Engine Light


Therre is no DTC code "5". The DTCs start at 12. If the knock sensor (there are actually 2) was bad, you would have an acceleration issue. The knock sensor changes the timing of the spark to eliminate detonation, or "pinging". Do you have a "Ping" condition/valve rattle on acceleration?
To reset the light, open the hood, remove the 15 amp EFI fuse for 5 minutes. Replace it, and start the car and drive it until it reaches operating temperature. If the light comes back on instantly, you have a bad sensor or a bad wire.
