Park/Neutral Switch Circuit
CIRCUIT DESCRIPTION:
The Park/Neutral switch contacts are a part of the Neutral start switch assembly. They are closed to ground in Park or Neutral and open in drive ranges.
The ECM supplies voltage through a current limiting resistor to PNK/PPL wire and senses a closed switch when the voltage on PNK/PPL wire drops to
less than one volt. The ECM uses the P/N signal as one of the inputs to control idle air, VSS diagnostics, and EGR. If PNK/PPL wire indicates P/N
