I posted about this a while ago and got no answer, so I thought I'd try again. I started seeing this code (16502 - coolant temp sensor signal too high) a few months back, and the car would have trouble starting every once in a while. Sounded simple, just needed a new sensor. So I got one. And the code came back. And kept coming back every time I started the car. So I got another new sensor, hoping I had purchased a faulty one to replace the original. The code keeps on coming. So, I tried all three sensors again, the original and both new ones, and got the same result.

So my question is, can anything else cause this code to throw? I know my coil packs are in need of replacement at some point soon, but the car still runs fine otherwise - the only other issue in the code log is a bad RF ABS sensor, which I have ordered and will be replacing next week.

Any thoughts? The CEL is an ugly thing to have staring at you every time you drive...

have you tried the diagnostics in the service manual?
