Land Rover Mass Air Flow Sensor - Walker ERR5595

Product Information

Mass air flow sensors are tasked with measuring the amount of air entering the engine via the intake. This mass air flow sensor is known as a hot film sensor which will suffer performance deterioration over time. The sensor is designed to be self cleaning. A faulty or non functioning mass air flow sensor will cause a check engine light and in some cases cause a limp mode. The best way to diagnose a faulty mass air flow sensor is to disconnect it and see if engine idle or performance improves.

• Check engine light illumniated with OBD codes related to MAF sensor faults
• Engine has rough idle and/or stalls
• Short term fuel trim is rich at idle or lean under load
• Constantly runs rich or lean
