Check Engine Light On and How to Fix It

The air sensor, also known as the Mass Air Flow (MAF) sensor, plays a vital role in the engine by measuring the amount of air entering the engine and sending this data to the engine control unit (ECU). The ECU uses this information to calculate the proper amount of fuel to inject, ensuring efficient combustion. Susuki Grand Vitara Signs of a Damaged Air Sensor: 1. Engine Jerk at Idle: If the air sensor is damaged, the engine may shake or jerk when idle, as the fuel-to-air ratio is disrupted. 2. Reduced Torque: A malfunctioning sensor can result in incorrect fuel injection, leading to reduced engine power and torque. 3. Irregular RPM: Fluctuating or inconsistent RPM readings can indicate a problem with the air sensor, as it fails to correctly measure incoming air. 4. Increased Fuel Consumption: An inaccurate air reading causes improper fuel injection, leading to inefficient combustion and higher fuel consumption. 5. Engine Won’t Start: In some cars, a faulty air sensor can prevent the engine from starting, although this issue is specific to certain vehicle models. 6. Check Engine Light: The dashboard’s check engine light may turn on, signaling an issue with the air sensor. A diagnostic scan can confirm the specific fault. Cause of Damage: The most common cause of air sensor failure is dirt accumulation, which reduces its accuracy and eventually leads to malfunction. To maintain engine performance, it’s important to regularly clean or replace the air sensor when necessary.
