Climate Control Exhaust Gas Sensor: Service and Repair







Air Quality Sensor (G238)

The air quality sensor is installed at the right front on the intake air grille in the plenum chamber.

The air quality sensor contains a highly sensitive electronic component which can be damaged if it comes in direct contact with solvents, fuels or chemicals.

Do not install a sensor that has been kept, for example, in a tool box.

Do not store removed sensors in areas where they can come into contact with solvents, fuels and certain chemical compositions (fluids or vapors).

Removing

- Remove right the plenum chamber cover.

- Remove the cover above the air intake shroud.

- Disconnect the connector - 1 - from the air quality sensor.






- Turn the air quality sensor 90° and remove it from the mount.

Installing

Install in reverse order of removal.
