A/C Refrigerant Pressure Sensor
An electronic A/C refrigerant pressure sensor is mounted in the evaporator
tube between the evaporator and the condenser. The sensor output to the PCM
is variable and is dependent upon pressure inside the line. A high line pressure
results in a higher voltage output. The PCM constantly monitors the A/C refrigerant
pressure in order to perform the following functions:
| • | Disengage the A/C clutch if the pressures are above 2826 kPa
(410 psi) |
| • | Disengage the A/C clutch if the pressures are below 207 kPa
(30 psi) |
| • | Boost idle air control to compensate for A/C load at idle |
The sensor is not serviceable. If the sensor fails, the sensor must
be replaced.
