This causes loss of power and jerking of the vehicle when accelerating. If the fuel filter is clogged in your Chevy Trax, not enough fuel can get into the engine. A faulty MAP sensor presents more or less the same symptoms as a faulty MAF sensor. Instead, the air mass flow rate is calculated by the control unit using the data from the MAP sensor. Note (MAP Sensor): If you can’t find MAF sensor in your vehicle, it is possible your vehicle may not have one, especially if its an older vehicle. But this should only be done after an extensive analysis as the MAF sensor may not be responsible for the symptoms of poor acceleration in your Trax. In case of doubt, the sensor may have to be replaced. However, it can happen that there are no error codes.

If you see P0100, P0101, P0102, P0103 or P0104 code in the OBD2 scanner, it indicates a problem with the mass air flow sensor. Reading out the fault codes using a diagnostic device is relatively reliable.

How to check if the MAF sensor is bad in Chevy Trax? 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 Trax, it can happen that increasingly inaccurate values are sent to the engine control unit. The mass air flow sensor is a wearing part. 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 Trax. What happens when MAF sensor malfunctions in Chevy Trax? It is not only important for power delivery in your Trax, 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 Trax 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 Trax 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 Trax, it can have a negative effect on the performance of the engine, as less air passes through the dirty filter which suffocates the engine.
