Gauge Your Mercedes Benz S500 Air Mass Meter

The air mass meter is an essential tool in the upkeep of any automobile. In charge of monitoring the air that enters the motor, it could substantially affect engine operation and fuel economy. It might be considered permanently free from damage, being tucked right in the middle of a protected portion of the engine. But as for all car parts, it also requires maintenance and constant check-ups. A faulty meter would incorrectly assess the amount of air entry and would, hence, deliver faulty information to the engine control module. Voila, expect wrong fuel volumes onto your car's cylinders! You wouldn't want a troublesome air mass meter, would you? Read on and learn some common symptoms of a faulty Mercedes Benz S500 air mass meter.

Consistent turning on of the check engine light

A dirty air mass meter is likely to cause your CEL to turn on. Locate the tool at the center of the large engine cover's far rear portion to check if it already needs cleaning. For a more accurate diagnosis, read the code displayed by the engine management checker. You can also bring this error message at any autoparts house for decoding, but purchasing an OBD2 reader can help you save time-and perhaps, money-from all the clueless guessing and diagnosing. If you confirm that your CEL switched on due to a contaminated air mass meter, solve the problem with the right spray cleaner and cleaning procedures.

The check engine light may also be triggered by loose connections in the air mass meter. This is usually resolved by cleaning or replacing the ground strap wire, which is at the bottom of the car. Locate the ground strap at the right side of the engine, close to where the transmission and the engine meet and check if the sensors are in good contact with one another.

Poor engine performance and low gas mileage

A faulty air mass meter can also cause the engine to completely stop after a little flooring. Other symptoms include idling, stalling, and refusal to accelerate. For a temporary solution to this, park and turn off your Mercedes Benz S500 first, and then turn it on again. However, it is important to attend to the real cause of the problem as soon as possible as it may cause further damage to the engine.
