Park/Neutral Position (PNP) switch is used only for the hybrid vehicle control system which controls the electric transaxle. PNP switch delivers an input signal to Hybrid Vehicle (HV) control Electronic Control Unit (ECU) to indicate transaxle gear position instead of the Engine Control Module (ECM) like all other models. Hybrid vehicle control ECU is referred to as HV ECU. The HV ECU uses input signal for controlling vehicle movement. PNP switch is located on end of shift lever assembly on steering column and may also be referred to as shift position sensor.
