Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ambient Pressure Sensor
The ambient-pressure sensor is installed directly in the engine control module; it s seated as a separate component on the printed circuit board. In the engine control module, the value is checked to ensure it remains within permitted limits.
A fault code is entered if the ambient pressure is not within the expected range. The ambient pressure is required for functions in the engine control module related to calculating the mixture composition. The ambient pressure falls the higher you go above sea level.
