Everything acts normal until I press the gas pedal and get a code 05. No clunk sound from the clunk sound maker. Hot battery leads at the PTSDM read 79-80v. Where should I start diagnostics? How to check the go-pedal potentiometer?
It’s this style:
Stick a pin in p3 wire insulation at controller. Should be over 2.4v. Goes to zero volts when pedal is pressed.
Hall effect throttles rarely fail. Unplug and reseat controller and throttle plugs.
Ok I’ll check those soon. Thanks.
What has happened to this car recently that made it stop running?
Have you been installing any accessories?
Moving any wires around?
As Inwo has pointed out, Remove and inspect the Main Harness 23 pin plug on top of your controller (special attention to Pin3), Reinstall and give it an extra push to make sure it is firmly seated. Try pedal press again.
Ok I’ll try these ideas soon. I’m traveling now.
This could be it because I just reinstalled the controller I thought it was malfunctioning so I sent it in but it tested good.
The first problem was flashing dash after New batts. New delta q. This was after it broke down on the road for the first time with my wife towed it home. In retrospect I should have pushed on the fuse because after reinstating the controller the dash was still flashing. Trying all options I pressed the fuse in harder and it fixed everything. But then first time ever 05 code.
So probably need to reseat the controller plug. Hopefully.
