Just wondering how commonly the TPS go out on an obs truck, i have an idle issue and a throttle flutter lie 5 seconds after start up and im wondering if it is a tps issue.
You can test the injector solenoids if you are up to it ,I swapped out the IDM already with a known good IDM, in trying to follow codes that i was told were found when i bought the truck, i know i could use a new main engine harness due to the current one on the truck being spliced together.
I found this... Hopefully it helps you...
You can test the TPS :You need to put a voltmeter across the GY/W and the GY/R wires on the connector to the TPS. With the key on, watch the voltage across the range of the throttle to see if there is any flat spots. You should see no less than .37 volts at idle position and no more than 4.5 volts at full throttle. The the third wire, (BRN/W), is the ref. voltage and should be 5 volts all the time.
