The Top 10 Engine Sensors Every Car Owner Should Know

DTC Codes: P0100-P0104, P1100-P1106.

Oxygen (O2) Sensor: Monitors the oxygen levels in the exhaust system to adjust fuel mixture for optimal combustion.

Effects of a Faulty Sensor: Decreased fuel efficiency, increased emissions, engine misfires.

DTC Codes: P0130-P0167.

Throttle Position Sensor (TPS): Tracks the position of the throttle plate to regulate the throttle opening.

Effects of a Faulty Sensor: Poor acceleration, hesitation, unstable idle.

DTC Codes: P0120-P0124.

Coolant Temperature Sensor (CTS): Measures the engine coolant temperature to aid in proper fuel delivery and cooling system control.

Effects of a Faulty Sensor: Engine overheating, inaccurate temperature readings, difficulty starting.

DTC Codes: P0115-P0119.

Crankshaft Position Sensor (CKP): Detects the rotational speed and position of the crankshaft for ignition timing and fuel injection synchronization.

Effects of a Faulty Sensor: Engine stalling, difficulty starting, misfires.

DTC Codes: P0335-P0339.

Camshaft Position Sensor (CMP): Determines the position of the camshaft(s) for precise fuel injection and ignition timing.

Effects of a Faulty Sensor: Rough running, misfires, decreased power.

DTC Codes: P0340-P0344.

Knock Sensor (KS): Identifies engine knocking or detonation, allowing the ECU to adjust ignition timing to prevent damage.

Effects of a Faulty Sensor: Reduced engine power, increased fuel consumption, potential engine damage

DTC Codes: P0325-P0332.

Manifold Absolute Pressure (MAP) Sensor: Measures the intake manifold pressure to calculate engine load and adjust fuel delivery.

Effects of a Faulty Sensor: Poor acceleration, rough idling, decreased fuel efficiency.
