Engine sensors are vital components that monitor various aspects of your car's performance, feeding critical data to the engine control module (ECM) to ensure optimal efficiency and emissions.
Key Engine Sensors
- Oxygen (O2) Sensor: Measures the amount of unburned oxygen in the exhaust to adjust the air/fuel mixture.
- Mass Airflow (MAF) Sensor: Measures the volume and density of air entering the engine, allowing the ECM to deliver the correct amount of fuel.
- Coolant Temperature Sensor: Monitors engine temperature, influencing fuel delivery, ignition timing, and cooling fan operation.
- Throttle Position Sensor (TPS): Monitors how far the throttle valve is open, indicating driver demand.
When Sensors Fail
A failing sensor can cause a variety of drivability issues, including poor fuel economy, rough idling, stalling, surging, and increased emissions. It will also typically trigger the Check Engine Light.
