I own a 1987(10/86) Pathfinder and I have a problem involving code 42 TPS. The input voltage is supposed to be variable from 0.5 to 4.0 volts and its supposed to change when the accelerator is depressed, but when I measure it I only measure 0.03 volts body grounded and 0.006v grounded to the black wire from the tps harness and nothing inbetween. I've tried using a different ecu and the same thing is occurring. I installed a new TPS and I've also checked continuity on all the wiring to the tps and everything is fine. I was measuring the voltage after installing and it all of a sudden dropped off and never returned. TPS was checked and is fine.
have the same problem?
