* Mass Airflow Sensor (MAF) problems: The MAF sensor measures the amount of air entering the engine. A dirty or faulty sensor will give incorrect readings, leading to a lean or rich fuel mixture and triggering the light.
* Throttle Position Sensor (TPS) issues: The TPS tells the computer the position of the throttle. A faulty sensor can cause inaccurate fuel delivery and ignition timing, resulting in reduced engine power.
* Crankshaft Position Sensor (CKP) problems: This sensor tells the computer the position of the crankshaft. A failing CKP sensor can disrupt ignition timing and cause misfires, leading to the reduced engine power light.
* Camshaft Position Sensor (CMP) problems: Similar to the CKP sensor, a faulty CMP sensor affects ignition timing.
* Oxygen Sensor (O2) issues: The O2 sensor monitors the exhaust gases to help the computer adjust the air/fuel mixture. A malfunctioning O2 sensor can lead to an incorrect mixture and reduced power.
* Dirty or clogged fuel injectors: If the fuel injectors are clogged, the engine won't receive the proper amount of fuel, leading to reduced power.
* Ignition system problems: This could include faulty spark plugs, wires, or the ignition coil itself. Misfires will result in reduced power.
* Low fuel pressure: A problem with the fuel pump or fuel filter could restrict fuel delivery.
* Vacuum leaks: Leaks in the intake system can disrupt the air/fuel mixture.
What you should do:
1. Check the engine light codes: Use an OBD-II scanner (available at most auto parts stores) to read the diagnostic trouble codes (DTCs). These codes will give you a much better idea of the specific problem.
2. Consult a repair manual: A repair manual specific to your 2002 Chevy Camaro will give you detailed information about diagnosing and fixing potential problems.
3. Take it to a mechanic: If you're not comfortable diagnosing and repairing the problem yourself, take your Camaro to a qualified mechanic. They can diagnose the issue and perform the necessary repairs.
Simply resetting the check engine light won't solve the underlying problem. Ignoring the "reduce engine power" light can lead to further damage and expensive repairs down the line. Addressing the issue promptly is essential.
