ITEM DESCRIPTION
1 Air Conditioning (A/C) temperature pressure sensor - Compressor inlet
2 A/C temperature pressure sensor - Compressor outlet
3 A/C temperature pressure sensor - Recovery heat exchanger outlet
4 A/C temperature pressure sensor - Electric drive cooler

The Air Conditioning (A/C) temperature pressure sensors provide the HVAC control module with refrigerant temperature and pressure data from the A/C system.

There are 4 A/C temperature pressure sensors to make sure that the A/C system operates correctly.

COMPONENT DESCRIPTION ELECTRICAL CONNECTOR
A/C temperature pressure sensor - Compressor outlet
  • High Pressure (HP) sensor on the electric A/C compressor outlet side of the A/C system.
  • Makes sure that the A/C system does not exceed the maximum operational pressure.
  • The sensor is hardwired to the HVAC control module.
  • A 4-pin connector to the wiring harness.
  • The 4-pin connector has the following electrical connections to the HVAC:
    • Electrical 5V power supply
    • Temperature signal
    • Pressure signal
    • Ground connection.
A/C temperature pressure sensor - Compressor inlet
  • Low Pressure (LP) sensor on the electric A/C compressor inlet side for the A/C system.
  • Makes sure that there is sufficient refrigerant in the A/C system for the electric A/C compressor by monitoring the refrigerant temperature and pressure.
  • The sensor is hardwired to the HVAC.
  • A 4-pin connector to the wiring harness.
  • The 4-pin connector has the following electrical connections to the HVAC:
    • Electrical 5V power supply
    • Temperature signal
    • Pressure signal
    • Ground connection.
A/C temperature pressure sensor - Recovery heat exchanger outlet
  • LP sensor on the outlet side of the recovery heat exchanger when it operates as a evaporator.
  • Used to determine the amount of heat recovered from the recovery heat exchanger.
  • The sensor is hardwired to the Powertrain Control Module (PCM).
  • The sensor data is sent from the PCM to the HVAC through the High Speed (HS) Controller Area Network (CAN) power mode zero systems bus.
  • A 4-pin connector to the wiring harness.
  • The 4-pin connector has the following electrical connections to the PCM:
    • Electrical 5V power supply
    • Temperature signal
    • Pressure signal
    • Ground connection.
A/C temperature pressure sensor - Electric drive cooler
  • LP sensor on the outlet side of the electric drive cooler.
  • Monitor the temperature of the refrigerant only.
  • Used to determine the amount of heat recovered from the electric drive temperature control system.
  • The sensor is hardwired to the HVAC.
  • A 4-pin connector to the wiring harness.
  • The 4-pin connector has the following electrical connections to the HVAC:
    • Electrical 5V power supply
    • Temperature signal
    • Ground connection
    • Only 3 electrical connections used.
