Hello!
So I replaced my TPS about 9 months ago with one from Autozone after seeing symptoms of failure. I started noticing the same symptoms some time last week, and chalked it up to a crappy Autozone part, so I replaced it again with the highest quality sensor that my local NAPA carried (Eichlin Ignition I believe).
Now just a few days later, I'm seeing the same symptoms again (intermittently). I'm hoping I just got unlucky with a defective sensor, but am worried it could be something else (hopefully not TCM)..
I've cleaned up all the grounds except the one next to the oil dipstick tube which from other threads I've read doesn't have anything to do with the sensor or the ECM or TCM (although feel free to correct me if I'm wrong).
I'm going to return the sensor to NAPA and get a replacement, hopefully it goes away after that.. Does anyone know what else this could be?
My symptoms are:
- Strange shifting (shifting at higher RPM than usual), and a little rough
- When accelerating at highway speeds in Overdrive, I have some serious surging or loss of power(idk what else to call it). It almost feels like it wants to downshift but won't. I would imagine that if it wasn't in OD, the RPMs would be dropping.
- Sometimes won't shift into Overdrive at all
