My Fords never done that

I'd prefer a driveshaft to what mines done... Failing the output voltage regulator in the powertrain control module (runs the engine sensors basically). Got a wrecker part to replace it, which should be a fairly simple process to code the new unit into the chassis/ecu/pats systems (pats being antitheft crap). Alas, the new $12K scan tool requires internet to confirm the identity and ensure nothing dodgy is going on with the immobiliser recode. Good in theory, except where I am 6km out of Tauranga we don't have good enough internet coverage/data to convince the scan tool's website all is cosher. Gotta wait for another guy to get some time to come up and do the recode of the security system, with his older non-data gear. Once thats done and the new module have the right chassis number in it and the key fobs are recoded then the sparky can check everything else out and redo the injector calibration offset codes etc etc. FFS what a drama! Gimme a simple driveshaft any day.

....depends what that driveshaft does on its way out
If I was closer I'd fix that for ya.

Oops... That looked like a cockup.

Yeah total pain in the arse for mine - what it's doing is the sensor output voltage which should be a rock stable 5.00v is wavering between 4.94v or less to 5.06v or more - this is compounding on all of the sensors from the voltage variability (it's fluctuating multiple times a second and as all the sensors are voltage based it's throwing all of the sensor readings out which means the PCM doesn't know which way to adjust the control valves) and this is causing random limp modes and check powertrain lights to come up without lodging a DTC. Made it bloody hard to diagnose what was causing it and local ford's answer was start swapping parts out like injection pump, common rail, injectors, in tank lift pump and tank level sender (four of those so far) but that wasn't the issue. Ford should have fixed it under warranty but by them failing and walking away from it it's been left to me to sort. Useless really.

If I had a usb-obdII link cable I'd download Forscan and do the thing myself. Luckily I have a spare hack at the mo so having the Ford out to pasture isn't too much of a problem.

A bit more kneed it would fix that
