TPS sensor? I've gone through 3 in 4 months.....

[Logan]

Anyone else have issues with their Throttle Positioning Sensors?? I've had to replace 3 in the past 4 months. I've checked for pinched wires and things like that with no avail. This latest one malfunctioned when I went to recharge my air conditioning over the weekend. I just pulled the plug on it so it would stop stalling but of course it shifts weird now. Any ideas????

Sorry to hear this, I've never replaced mine. I'd say get it to a shop and diagnose it prior to replacing it again.

First thing I'd check are the harness grounds on the engine, and make sure that the engine and chassis are bonded. Loose grounds and bonding straps will fry stuff.

edit: spelling

This is true. It almost sounds too simple or too easy, but poor ground is a common problem.
