1. Oxygen Sensor.
The oxygen sensor measures the amount of unburned oxygen in the exhaust gases. A faulty oxygen sensor can lead to an incorrect air-fuel mixture, resulting in either a rich or lean condition. Both scenarios can significantly decrease fuel efficiency. Â
2. Mass Airflow Sensor (MAF).
The MAF sensor measures the amount of air entering the engine. An inaccurate reading can disrupt the air-fuel mixture, leading to incomplete combustion and reduced fuel economy. Â
3. Throttle Position Sensor (TPS).
The TPS monitors the throttle position. A malfunctioning TPS can provide incorrect information to the ECU, affecting the air-fuel mixture and causing the engine to run inefficiently. Â
4. Fuel Pressure Sensor.
This sensor measures the fuel pressure in the system. An inaccurate reading can lead to an incorrect fuel-to-air ratio, resulting in decreased fuel efficiency and potential engine damage. Â
5. Temperature Sensor
The engine temperature sensor monitors the coolant temperature. An incorrect reading can affect the engine’s combustion process, leading to suboptimal fuel efficiency and potential engine damage.
