wrench light, no throttle responce?

[k98dave]

Got wrench light, and there is no engine response to throttle. I checked all the PCM related fuses in main pwr box as there are no specific fuses listed for fly by wire throttle and they were good. Suggestions?

Any codes?

Any codes?

No codes on my little cheap reader. My son will check with his later this evening. I'm hoping its the pedal assy. and not the throttle body motor. Been told that is not a serviceable item.

Disconnect the battery for 30 minutes, make sure all connectors on the throttle body and throttle pedal are secure, reattach the battery after the 30 minute PCM drain and see if anything changes.

I had a wrench code once with the same symptoms. My mechanic (me) had been servicing the air filter and the dope forgot to plug in the Mass Airflow Sensor. Need to fire that guy!

Not that it is your problem as well, but if you have been working on it, go over your work. Something might be unplugged.

Nothing was being worked on, had batt disconnected for an over an hr no results, car starts and idles fine, I'm thinking it's the pedal. I will remove it tomorrow, haven't found any info on how to test it. I have an OEM Ford pedal assy. coming from LMR. Should be here in a day or so.

I think the throttle body took a dump.Same symptoms mine had....

It was the throttle pedal assy. Not much to see inside, Magnetic Hall affect sensor inside housing with 6 pin connector with IC's that read and interpret changes in magnetic field. $80 dollars for entire assy. with about $10 worth of plastic & parts.
