* Mass Air Flow (MAF) sensor: Measures the amount of air entering the engine. This is crucial for determining the amount of fuel to inject.
* Throttle Position Sensor (TPS): Indicates the throttle's position, influencing fuel delivery.
* Oxygen Sensor (O2 sensor): Monitors the exhaust gases to adjust the air/fuel mixture for optimal combustion and emissions.
* Crankshaft Position Sensor (CKP sensor): Provides the engine's rotational speed and position to the PCM.
If you're experiencing fuel-related issues, it's unlikely the problem is a single "fuel compensation sensor." Instead, a diagnostic trouble code (DTC) scan by a mechanic or using an OBD-II scanner is necessary to pinpoint the faulty sensor or other component contributing to the problem. The problem might even lie within the PCM itself.
