Description The fuel pressure sensor (FPS) is installed on the top of the low pressure fuel pump and measures the pressure in the low pressure fuel line.
Removal In case of removing the high pressure fuel pump, high pressure fuel pipe, delivery pipe, and injector, there may be injury caused by leakage of the high pressure fuel.
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature. 1. Sensor Ground2.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Recover the refrigerant with a recovery/ recycling/ charging station. 3. When the engine is cool, drain the engine coolant from the radiator. 4. Remove the expansion valve cover (A).
