![]() ![]() It is possible for the wires in the connector to break, causing the mass airflow sensor to not work. ![]() When doing this job, the mechanic may recommend changing the electrical connector that connects the mass airflow sensor to the car's computer system. The mass air flow sensor is part of the engine’s intake system and is located between the air filter and the throttle body. If the vacuum hoses are leaking, it will give the same error code as mass airflow sensor failure. The most common signs of bad mass air flow sensor (MAF) in Mini are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. When a vehicles mass airflow sensor is faulty or defective it can cause a variety of problems, and usually results in very poor performance from your engine. It is common for the mass airflow sensor to get dirty (if the air filter is dirty) and lose the ability to read the amount of air coming in the engine. ![]() If the sensor goes bad, the engine will not know the right amount of fuel to add, causing problems including poor gas mileage, lack of power and more. Question: My mass air flow sensor on an 88 Camaro 2.8 reads 5-volt reference between signal and ground while running and unplugged, on the ECM side, at idle. By far, the most common cause of MAF sensor failure is a dirty sensing element. The computer in the car reads the amount of air coming into the engine from the mass airflow sensor and then calculates the correct amount of fuel needed for proper engine performance. The Most Common Cause of MAF Sensor Failure. For an engine to perform properly, it needs a specific amount of air-fuel mixture. The oxygen sensor provides vital air-fuel mixture. The mass airflow sensor measures the amount of air entering the engine. Faulty Oxygen Sensor: Due to long exposure to hot exhaust gas, your oxygen sensor might need replacing. All cars take air from the outside and pass it into the engine through the air filter. If your car is stalling or hesitating, or if youre using more.
