2002 Taurus strange electrical problem

Post by RoyGray » Wed Jun 06, 2018 7:34 pm

Good evening.
My 2002 se is doing some crazy things.
The gas cap light stays on, ive replaced the cap, canister and pressure sensor.
But here’s the weird part.
Sometimes the brake light comes on and the gas cap light goes out. The brake light will stay on for 15ish minutes and then the traction control light comes on for a few seconds and then goes out and and then the gas cap ligh5 comes back on.
I’ve had the battery and alternator check and they are both good.
Any clue what’s going on here?

Check all the grounds, the main one is from the battery, I had a problem with my dash cluster, turns out the ground was tight, but the paint from the factory was causing an intermittent problem, I removed the bolt that held the ground to the body, took some sand paper, removed the paint to bare metal, installed the ground with some wire grease and all the problems so far are gone. Hope this helps
