2000 Jeep Grand Cherokee Repair Question
Jeep Grand Cherokee Engine Problem
Did you do any diagnostics on the TPS circuit? Fault codes never say to replace parts. They only indicate the circuit or system that needs to be diagnosed. With the ignition switch on, measure the voltages on the three wires to the TPS. That has to be done with it connected by back-probing through the rubber seal in the wire side of the connector. If this is an intermittent problem, those measurements must be taken when the problem is occurring, (not necessarily with the engine running).
