Good To Know

Q: What are common signs of a bad mass air flow sensor? A: Rough idle, hesitation, stalling, and a check engine light are typical. Replacing the sensor often clears these symptoms when the fault code points to air metering.

Q: Does this sensor need programming after installation? A: This sensor installs as a plug-and-play replacement with no programming on the 240. Clear the fault codes and drive briefly so the fuel injection system can relearn trims.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
