Help your engine computer get an accurate read on incoming air with the Standard Ignition Mass Air Flow Sensor MAS0291. It is a direct-fit replacement for the 1997 and 1999 Mercedes-Benz C230 (L4-2.3L) and the 1998-1999 Mercedes-Benz SLK230 (L4-2.3L). It is supplied as a complete assembly with the housing included.
The mass air flow sensor measures the air entering the engine and reports that reading to the ECU. The ECU uses it to balance and deliver the correct air/fuel ratio for a clean burn.
Specifications: The sensor is made of plastic and has 2 bolt holes. It uses one oval, female connector with 5 male blade terminals. The quantity per application is 1. Country of origin: Germany.
Signs that a mass air flow sensor may need replacing include a check engine light, rough idle, hesitation on acceleration, hard starting, or reduced fuel economy. These symptoms can have other causes, so diagnose the problem before replacing the sensor. If a failed MAF sensor is the cause, MAS0291 replaces it.
