DTC P2159: Range/Performance Problem in CVT Speed Sensor Circuit: General Description
The CVT speed sensor detects the number of revolutions of the secondary drive gear and sends a pulsing signal to the transmission control module (TCM). The TCM converts the pulsing signal into a vehicle speed.
If the vehicle speed measured by the CVT speed sensor is lower than the value that is estimated based on the vehicle speed measured by the vehicle speed sensor (VSS), a malfunction in the CVT speed sensor is detected and a DTC is stored.
