Description Rail Pressure Sensor (RPS) is installed on the delivery pipe and measures the instantaneous fuel pressure in the delivery pipe. The sensing element (Semiconductor element) built in the sensor converts the pressure to voltage signal.

Removal 1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off. 2. Disconnect the negative cable from the battery. 3. Recover the refrigerant with a recovery/charging station.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Remove the heater and blower unit.(Refer to HA group – heater unit). 3. Remove the blower unit (A) from the heater unit after loosening a mounting bolt and 3 screws. Make sure that there is no air leaking out of the blower and duct joints.
