Transmission Position Switch/Sensor: Description and Operation
PRNDL-P/N Switch
The PRNDL switch is part of the transmission Neutral Safety-Back Up (NSBU) Switch, located on the top of the transaxle. The PRNDL switch provides
four inputs to the PCM to indicate the transmission gear position. Gear position information is used by the PCM to control shift solenoids and VCC
operation. Improper switch operation will cause PCM code E091/E91 to set.
