The code indicates the TPS is still bad and the code is usually right, but it could be a wiring issue at the TPS connector or less likely a computer issue.
To test the TPS circuit, you need to check voltage and ground from the ECM - 5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM requires monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is jumpered to low when the jumper is removed.

The Pink and green wires in the bunch of wires near the right wiper under the hood has been cut by the belts I need to know what those wires are and how to fix them. I have picsbut dont know how to post...


The wire from the battery cable is the body ground. It should be connected to the inner fender on a bolt. As for the two broken wires, can you put them back together with sealed **** connectors.
