Where are the mass air flow sensors on a Porsche Cayenne?
On a Porsche Boxster, put the convertible top in the service position, then remove the engine cover. Locate the mass airflow sensors. On this Porsche Cayenne, there are two mass airflow sensors mounted on the air intake hoses. On the Boxster, the sensor is located on the driver’s side right after the air filter housing.
How do you clean a Porsche MAF sensor?
Pay attention to the arrow that shows the direction of airflow. If you are cleaning your existing Porsche MAF sensor, make sure to spray it with a Mass Air Flow Sensor Cleaner. Tighten the Torx screws. If the screw holes don’t line up correctly, remove the Porsche MAF sensor and rotate it 180 degrees. Porsche MAF sensor fits in only one direction.
What is fault code for Porsche mass air flow sensor?
This is a list of possible fault codes that often point to a defective Porsche mass airflow sensor. P1124 – Oxygen sensing adaptation range 1 (cyl. 1-3) at enrichment limit. P0102 – Oxygen sensing adaptation range 2 (cyl.. 4-6) at enrichment limit. P0103 – MAF (Mass Air Flow) sensor or VAF (Volume Air Flow) sensor high input
Why is my mass air flow sensor not working?
Porsche mass airflow sensors fail due to dirt that collects on the thin film used to detect airflow and temperature. Oiled air filters are known to coat the MAF film causing it to malfunction. Bosch makes the OEM mass airflow sensor for the majority of Porsche vehicles.
