Transmission Position Switch/Sensor: Description and Operation
PRND Switch (Transmission Range Switch)
The Transmission Range Switch (PRND) switch is mounted to the side of the transaxle and is part of the Park Neutral Position (PNP) switch. The
PRND switch is used by the PCM to indicate the actual gear selected. The PRND is made up of 4 individual switches. The scan tool indicates ON or
OFF for each switch depending on the position of the gear selector lever. The combination of ONs and OFFs will indicate the gear selected. If the
combination of ONs and OFFs is invalid, a DTC is set.
