CM2150 Electronic Control System – 019-134   Ambient Air Temperature Sensor

The ambient air temperature sensor and the barometric pressure sensors are combined into a single sensor. The sensor is located in the air intake connection between the air cleaner and the turbocharger compressor inlet.

Lift up on the locking tab and pull the electrical connectors apart.

Remove the capscrew.

Remove the sensor from the engine by pulling straight up on the sensor. Be careful not to damage the o-ring seal when removing the sensor.

Inspect the engine harness connector and the ambient air temperature/barometric pressure sensor for the following:

• cracked or broken shell
• missing or damaged connector seals
• dirt, debris, or moisture in or on the connector pins
• corroded, bent, broken, pushed back, or expanded pins.

Inspect the ambient air temperature/barometric pressure sensor for the following:

• swollen o-ring
• nicks or cuts in or on the o-ring.

Make sure the new sensor has an o-ring.

Install the new sensor into the engine.

Tighten the capscrew.

Push the connectors together until they lock.

An audible click will be heard as the connector locks in place.
