You can either buy a OBD II monitor, plug is under the bottom of dash just right of the steering wheel. Follow instructions in operating manual of the tester. Write down the code(s). While you are there, you can erase the codes, which will turn off the engine light. When it comes on, it means something was detected by the onboard diagnostics, so it turns that light on to warn you.Check engine light on. How can I test or get it off?
Original owner of my 2003 T-Bird. Check engine light has gone on 3 times over the years. Once , merely opening then closing gas cap did the trick. Twice, when that failed, I took off the positive connection to the battery for a few minutes, replaced it and all was well.Check engine light on. How can I test or get it off?
This is a lot of unneccessary work and also resets everything else in the car. Get an OBDII scanner and you can read and reset the codes with the touch of a button. Some OBDII scanners are dirt cheap, work on most cars, and really every automobile owner should have one for troubleshooting purposes.I took off the positive connection to the battery for a few minutes, replaced it and all was well.
My 2005 Tbird Check engine light came on. I checked the gas cap and it seemed loose so I tightened it. But the check engine light is still on. How long before it goes off?Original owner of my 2003 T-Bird. Check engine light has gone on 3 times over the years. Once , merely opening then closing gas cap did the trick.
