Monitor Description
WARNING: This page is about a different car, the 2016 Toyota Highlander, 2015 Toyota Highlander, and 2014 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
This DTC indicates a problem with the park/neutral position switch assembly or the wire harness in the park/neutral position switch assembly circuit.
The park/neutral position switch assembly detects the shift lever position and sends signals to the TCM.
For safety, the park/neutral position switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The park/neutral position switch assembly sends a signal to the TCM according to the shift lever position (R or D). The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The TCM will illuminate the MIL and store this DTC.
