2006 F150 XLT: the wrench light came..drove..light went..TPS

Resolved Question:

2006 F150 XLT SCREW 5.4L 62000 miles

About 2 months ago the the vehicle hesitated and the wrench light came on an eventually the MIL light illuminate, busy at work so I drove it for two weeks worked fine with the MIL light on, eventually the MIL light went out, with no external reset. Pushed the TPS connection cable felt a click. The vehicle ran fine for about a month now the wrench light/hesitation came back on and the MIL light came back on pulled code P2135, reset the MIL the vehicle worked fine for about two weeks, now I get the wrench light and hesitation, no MIL light yet - just seems to be in the cool damp morning.
Questions:
1)Is this the TPS?
2)On earlier model (2004) when the TPS was changed the PCM required reprogramming - is this true for 2006 and later models?
3)Is there a quality aftermarket replacement or should I stick with Motorcraft?

This code is directly related to throttle position sensor, but more accurately, it is a fault in correlation between tp sensor A & B, with the drive by wire system there are two tp sensors that compare with each other as the throttle is pushed and released, I would recommend to replace the throttle body assembly which comes with both sensors and throttle actuator, there is no programming required to replace this and everything is all set up so it is just a simple bolt on process.

Where can I find a schematic of the TPS circuit - I have the shop manuals, but did not look through them that carefully - I'm curious

What is this reprogramming on earlier TPS


Expert:  Brian replied 4 years ago.
There was a service bulletin for reprogramming the PCM for codes P0505 and/or P0506, with a hesitation and low idle problem. This was also designed to prevent sludge build up in the throttle body. If you haven't had your PCM reprogrammed it is a good idea to have it done to update your computer to the latest calibration, but it wouldn't fix your concern.
