lukeduke Posted August 21, 2013 Share Posted August 21, 2013 I can't seem to figure this out. I have no responce when I hit the throttle. I'm wondering whats the best method to fix this problem the "TPS" came up when I got dyinostics checked. But Im wondering if I can check the voltage and what it should be. Anyone have the same problem or think what I could do to fix this would help alot Quote Link to comment Share on other sites More sharing options...
GearheadGrrrl Posted August 21, 2013 Share Posted August 21, 2013 Not sure what the voltage specs should be, but the "throttle" is just a rheostat hooked to the pedal. Quote Link to comment Share on other sites More sharing options...
bbigrig Posted September 8, 2013 Share Posted September 8, 2013 Your TPS sensor is a potentiometer. It works off of 5 volts coming into the sensor. anything less then .25 of a volt it gets a low voltage code. anything more then 4.75 volts is a high voltage code. No voltage heading back to ECM from TPS for 5-7 seconds is a code for no signal from TPS or signal drop out. should have 3 wires, (5 volt feed--signal back to ECM--ground) Find out what the code is for and use this as a map to figure it out. if its a 5 wire TPS it doesn't use 2 of the wires unless it is Cummins powered.

keg1 Posted September 13, 2013 Share Posted September 13, 2013 I had a wire break at the throttle pedal on my 2000 Ch. It would idle but nothing when you stepped on pedal. Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted September 14, 2013 Share Posted September 14, 2013 sorry guys I don't have a new enough truck, but you can test most potentiometers with a multi meter on the ohms setting with the pedal unplugged . using the ground and the signal termanals in the throttle side of the plug,connect the meter then slowly depress the pedal and you should see a value count up or down depending on arrangement of the switch if you see gaps in the counting [dead spots] replace the switch.
