[QUOTE="RossKean, post: 1450409, member: 19880"] I'm not sure how you could easily test it without removing it from the circuit. Easier to unplug it and be able to meter the connections directly rather than break insulation or try to back probe the connector. (Not to mention the unknown contribution of components attached to the TPS.) Your method is not only appropriate but vastly easier than any alternative. The following is a screenshot for testing the TPS from the FSM. This is for a Gen II but procedure, if not values, should be similar for other generations. Note: While this checks the resistance range of the device, it doesn't test whether there might be places where resistive material is worn and the wipers might not make good contact. Still, it is a test that tells whether the part is completely FUBAR. They are using an ohmmeter with the TPS disconnected from the system... Their spec just uses the value for maximum resistance without any specs for minimum (zero?) or mid. [ATTACH type="full" width="307px"]2837[/ATTACH] [/QUOTE]
