The IDL switch is part of the TPS. It goes open circuit when the throttle
butterfly is fully closed, and tells the ECU to change from the "run" fuel map to the "idle" fuel map. It is one of the requirements that must be met before the ECU will go into diagnostic mode. If you saw no change when shorting the plug, then the ECU did not go into diagnostic mode. You need to set the IDL switch with a feeler gauge as per the FSM. The switch needs to change state as the throttle butterfly opens. If it does not, strange things happen  Cheers... jondee86 |
