Charge Air Pressure Sensor
WARNING: This page is about a different variant/trim than selected.
The charge air pressure sensor is located in the charge air cooler inlet pipe. The sensor is connected through a hose to the charge air outlet pipe from the turbocharger.
The charge air pressure sensor has a 3-pin connector.
The 3-pin electrical connector provides the following connections:
- A 5V reference voltage from the PCM .
- A pressure signal to the PCM .
- A ground connection.
The charge air pressure sensor uses a diaphragm transducer to measure pressure.
The PCM uses the sensor signal for the following functions:
- Maintain charge air cooler charge air pressure.
- Reduce exhaust emissions when driving at high altitude.
- To aid the air path diagnostics.
