Checking Your AFM and TPS


Get a new OE or OEM TPS


[quote=“Som” post=81600]Tested the TPS off the car – figured I’d do this first instead of testing at the DME in case it failed, and it did. It only occasionally closed 18/3 at WOT. Usually didn’t close them at all.

Drilled the 3/16" hole, sprayed brake cleaner in there, let it dry. Still failed.

Is it worth/easy to fix this reliably or am I better off just buying a new one? I don’t mind trying to fix it, I just want the fix to be reliable.

I had some luck soaking mine in parts cleaner. But I can’t vouch for long-term reliability yet.
