does any1 know how to check the tps? im getting a tps voltage low and tps inactivity readings on my scantool

should get a 5volt ref signal. and it will vary with throttle postion

is there a way to check it with a multimeter?????

10-04 previous post.. should have +5 v between ref voltage gray wire and ref ground black wire. Then move positive lead to dark blue wire.. it should read 1 V or lower with throttle closed (TPS%=0) and smoothly increase to 4.5-5.0V as throttle opens all the way (TPS%=100). If there is a flat spot or the voltage jumps erratically replace the TPS.. Also you could try your scantool w/ignition on and engine off to see if it gives dependable voltage readings, I have never tried that procedure. ...Bob D

Im getting the 5v from grey to black, but 2v on the blue wire, and 2.5v wot on the blue wire, and thats with engine off. does it have to be running to do this??

2.5v WOT is WAAAAY too low. Should be 4-4.5v WOT. I actually don't get over 4v with mine, but I chalk it up for being a stupid 93 lol

2v is also waaaaaay too high for closed throttle. Should be .54-.68v

I will save the time and trouble of explaing and just give you the link to a good write up with accurate info

If you have a scanner, you don't even need a meter. The scanner will read voltage and throttle position as you move the pedal with the key ON. Engine does not have to be running.

i have a scanner, but i dont know how to use it for crap. its an AutoTap. I use it to check my SES light, and data logging. as for checking voltage on individual parts, i have no idea on how to do that.

Look through the parameters until you find it. It's not rocket science.
