The A/C refrigerant pressure sensor signal is implausible against operating conditions. Reading does not change as expected when the compressor cycles or ambient conditions change.
Affected components
- Ac pressure sensor
- Ac compressor
Common causes
- High likelihood: Pressure sensor drift
- Medium likelihood: Refrigerant charge incorrect
- Low likelihood: Wiring fault
