Symptoms of Failing MAF Sensor and Fuel Efficiency Impact
A failing MAF sensor in a Toyota Camry often manifests through symptoms like rough idling, poor acceleration, and a decrease in fuel efficiency. When the MAF sensor sends incorrect data to the ECU, it results in improper fuel mixture adjustments, leading to the engine running either too rich excess fuel o r too lean insufficient fuel, causing engine performance issues. In Pakistan, where dusty roads are common, MAF sensors can easily get clogged. Owners can diagnose a faulty MAF sensor by checking for error codes, inspecting the sensor for physical damage o r dirt, and cleaning o r replacing it if necessary.
