87Fathpinder Posted June 5, 2013 Share Posted June 5, 2013 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 and it doesn't change. I've tried using a different ecu and the same thing is occurring. I've also checked continuity on all the wiring to the tps and everything is fine. Any ideas?

Kingman Posted June 6, 2013 Share Posted June 6, 2013 I assume you've replaced the TPS...? Link to comment Share on other sites More sharing options...
87Fathpinder Posted June 6, 2013 Author Share Posted June 6, 2013 yeah, new tps. no wiring issues found, continuity throughout. am I missing something? it gets the 5v power source, the ground is fine. Link to comment Share on other sites More sharing options...
Kingman Posted June 6, 2013 Share Posted June 6, 2013 Kinda weird, is yours a 5-speed or automatic? There's two things built into one TPS, an idle/full throttle switch and a potentiometer for the automatics. Link to comment Share on other sites More sharing options...
87Fathpinder Posted June 6, 2013 Author Share Posted June 6, 2013 it's a 5sp SE vg30i Link to comment Share on other sites More sharing options...
87Fathpinder Posted June 6, 2013 Author Share Posted June 6, 2013 it might be worth mentioning that while I was originally trying to adjust it I was measuring voltage fine and it started out of nowhere not reading healthy voltage, millivolts, almost none...

Slartibartfast Posted June 6, 2013 Share Posted June 6, 2013 Can you test your meter on something else to make sure it's not tweaking out? Link to comment Share on other sites More sharing options...
87Fathpinder Posted June 6, 2013 Author Share Posted June 6, 2013 I've tested the meter, no problem measuring any other voltages. Link to comment Share on other sites More sharing options...
