Offers troubleshooting guidance

Due to their delicate nature and tendency to be misdiagnosed, air mass sensors have notoriously high return rates in comparison to other vehicle electronic components.

Owing to increasing requirements of environmental protection measures, new generations of air mass sensors have become more and more precise– but also more sensitive. A defective or clogged air mass sensor can supply incorrect input signals to the ECU which, as a result, controls other components incorrectly. Cambiare offers guidance in the form of the below troubleshooting guide.

SYMPTOMS OF FAULT/FAILURE

• Black smoke or soot appearing from the exhaust

• Loss of power from the engine resulting in OBD light appearing

• Car falling into ‘limp mode’

POSSIBLE CAUSES FOR FAILURE

• Sensor element has been destroyed by dust particles from the air supply system

• Water contamination from a filter operating incorrectly

• Engine oil coming into contact with sensor element
