Default Throttle pedal position.... P2135!!!!!

I've been havingg an ongoing issue, p2135 code.

I replaced the throttle position sensor, no luck.
I bought a Zabteck throttle body and put it in, no luck.

Everytime I clean the throttlebody both the old one and new one I get by for about a week or two without the code, then it comes back on daily. What else should I try??? Could it be the wiring or something else??

do you have a tune for your car? if so try re-installing the tune.

your car has throttle-by-wire. that code says the PCM sees a disagreement between what the accelerator pedal sensor says and what the throttle position sensor says. That code does not mean the throttle position sensor is bad, nor does it say the throttle body needs to be replaced. you're shot-gunning parts onto your car without even trying to diagnose the problem.

Any suggestions on what next then? I was going from previous google searches of how others fixed the issue...

Why not follow Ford's diagnostic methods on tracking down the error?

..scroll down for the specific DTC, and it can take you to more pinpoint tests. If the links don't work, let me know (wherever you may find me ) and I'll look it up on my service dvd.

Thanks for that post. Found it on pg.138 of that link. It's telling me to compare the PID values for TP1 & TP2. Do I just need to run another datalog then? I have no idea how to read those logs - or what the acceptable value ranges are for those two PIDs. It says "refer to the chart in pinpoint test DV. Go to pinpoint test DV." Where is this? Thanks for your help

tp1 and tp2 are throttle position voltages from the tps sensor. Hook up a laptop and using the sct livelink software, search for the throttle position voltage values.

I'll hook that up tomorrow - just curious what the fix is if they are outside of the allowable ranges?

So I'm now leaning on it being the throttle pedal sensor... Anyone know how to access this? Dave from X-C told me many have fixed it by cleaning this sensor - do I just take the pedal off and spray some air and wipe away or what?
