I have a '05 F150 5.4L and I'm getting a wrench light code P2106 and code p2135 accelerator pedal position sensor switch a b voltage correlation.It happened once and when I drove it the next day everything was fine Do I have to replace both the throttle position sensor and the throttle body?Also will the power train control module need to be reprogrammed to the latest calibration?Has anyone just changed the TPS and it worked without reprogramming?This only happened once but we use this truck for towing our camping trailer and I would hate for this to happen towing our trailer.Thanks

2004-2005 Mountaineer This article supersedes TSB 05-09-15 to update the Issue and Dealer Coding.
Some vehicles built 11/29/2004 and prior may exhibit the wrench light on with both P2106 and P2135 diagnostic trouble codes (DTCs). ACTION
Replace the throttle position sensor (TPS) following the instruction sheet included in the TPS service kit. Reprogram the powertrain control module (PCM) to the latest calibration using WDS release B36.11 and higher, or B37.2 and higher. This new calibration is not included in the B37 CD. Calibration files are also available at the website. CAUTION FAILURE TO FOLLOW THE TPS REMOVAL AND INSTALLATION PROCEDURE WILL RESULT IN DAMAGE TO THE TPS SCREWS.
It is for "2004-2005 Explorer, F-150" as well. I just had this on one last month, the TP sensor is updated, buy a Ford one not from vatozone or any aftermarket parts house. you'll need to have your PCM updated also.
Thanks Shawns Ford for your help and I definitively will be getting a Ford part.I looked at the label on my drivers door and my truck was built on 6/2005 not the 11/29/04 and prior which means I will not have to have my PCM updated.Thanks again
My truck had been having idle issues. Coming to a stop it would idle down really low and stall and then when restarted it would idle high (1000-2000 RPM). After a couple of drive cycles it would go back to normal and I wasn't getting any codes. I checked for vacuum leaks, cleaned the TB and MAF but continued to have the problem.
It just got worse yesterday and the wrench light and check engine light came on. I checked for codes and found P2106 AND
P2135. Looking at this thread I'm pretty sure it is the TPS that needs to be replaced. Since some have had trouble removing the old TPS without breaking the screws I decided to order a throttle body. Will I need to have the computer flashed with the update or is that only if the TPS is replaced on its own?
