How to check if the MAF sensor is bad in Chevy Impala? In rare cases, the MAF sensor can also be damaged by oil vapors flowing back out of the crankcase ventilation after the engine has been switched off. When driving fast in heavy rain, water can occasionally pass through the air filter, which can severely impair the function of the MAF sensor. However, the sensor can also malfunction earlier. With a noticeable loss of performance and high mileage, a defective MAF sensor should definitely be considered. As the mileage increases on your Impala, it can happen that increasingly inaccurate values are sent to the engine control unit. The mass air flow sensor is a wearing part. What causes MAF sensor to fail in Impala? This can cause the engine warning light to illuminate in the instrument cluster and the fault can be read out by a diagnostic device. The engine runs too “lean” or too “rich”. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. If the MAF sensor is defective or dirty, it does not send correct measured values to the control unit of Impala. What happens when MAF sensor malfunctions in Chevy Impala? It is not only important for power delivery in your Impala, but also for the lowest possible pollutant emissions. The mass air flow sensor is part of the engine’s intake system and is located between the air filter box and the throttle valve. Dirty or faulty mass air flow sensor (MAF)ĭefective or dirty mass air flow sensor (MAF) in your Chevy Impala can result in loss of power, uneven engine running, erratic idling, misfires, poor exhaust emission values including black smoke. So this is the first thing you should check. Replacing the filter on your Impala takes a few minutes and does not require any special knowledge. In the worst case, the engine can stall if the air filter is extremely clogged. This ultimately also increases fuel consumption. If the air filter is dirty in your Chevy Impala, it can have a negative effect on the performance of the engine, as less air passes through the dirty filter which suffocates the engine.
