tommyep82 Posted April 10, 2015 Share Posted April 10, 2015 I am getting 5 volts at idle possession, and changes gradually as I open throttle but then goes into minus voltage on the meter when it is near wot. Is this normal as I am getting a Splutter before red line when under full load. Quote Link to post Share on other sites
tommyep82 Posted April 10, 2015 Author Share Posted April 10, 2015 if I unplug the tps and probe the connection to loom I get 5 volts doin it one way and minis 5 the other way using the same earth (middle wire) is this normal? Quote Link to post Share on other sites
FrozenJakalope Posted April 10, 2015 Share Posted April 10, 2015 Your multimeter's lying to you ;) A negative voltage reading basically means you've got the leads the wrong way round when measuring DC. So, the voltage is coming in through the black and out through the red. On your original question, I'd check continuity with your MM diretly into the 3 pins on the TPS. At 0 throttle, you should have continuity from middle to top, from 25% to 75% you should get no continuity and from 75% up you should get middle->bottom. If there's any cross-talk between the pins I'd take the TPS off and crack it open and you should be able to see where the problem is easy enough. Quote Link to post Share on other sites
