intermittent limp home (wrench) mode
 

I did a search- and it lead back to the TB/ TP sensor.

My question is- how to diagnose to make it stop

My car has a HO Whipple, and dealer is 2 hrs away- so you see my desire to handle it myself...

My Shop Manual talkes about "always on and never on" conditions. Like I said this one is intermittent


Any thoughts?

Easy checks to do are to disconnect the negative terminal of the battery, and then take the connector off of the throttle position sensor on the throttle body. Check the female connector for corrosion and the male connector for bent or damaged pins. If everything checks out, I would disconnect the intake from the inlet side of the throttle body and move the throttle valves with your fingers to check for any interference. If everything there checks out, maybe you have a bad throttle position sensor. One other thing you can do to check your sensor is to datalog with your handheld tuner if you have one. SCT provides free software for their X-Calibrator series tuners and you just hook it to your laptop and you can monitor the throttle position angle as you drive and look for random fluctuations that would cause your error.

I tried all of the above - new TPS here I come!

Let us know how it works out....

I ordered the new TPS- after doing much searching. Seemed like most all of the dreaded wrench light probs were solved with a replacement. We shall see. I'll let you know> Thanks

couple of hunderd miles - no wrench

YAY

I'll keep this thread posted

UPDATE- driving car many miles daily. No wrench light. Looks to be the solution in my case> new Genuine Ford TPS. $40 from the internet. SWEET!

Thanks again, over and out- Steve
