I have never heard of a bad sender turning on the check engine light, you may have something happening with the cluster or possibly the BCM. Have had the codes checked?


I have the same issue. 2005 PT with 70,000 miles. Dealership replaced the fuel pump but the same warning light comes on again. Test reads that it is the fuel pump again..... Engine light and gas light comes on, fuel gauge drops to empty even if full. Then later or next day everything reads fine. My guess is some kind of bad sensor but dealer will do full diagnostic on it to try to figure it out. No way I am spending a ton of money on a 12 year old car. Will Fred Flinstone it and just track miles if necessary.
