What is the common check engine light for Acura RSX?

The common check engine light issues for an Acura RSX include:
1. Loose or Faulty Gas Cap: A loose or faulty gas cap is one of the common reasons for an illuminated check engine light. Tightening the gas cap should resolve the issue.
2. Engine Trouble Codes: The check engine light is connected to the engine control unit (ECU) or powertrain control module (PCM) of your RSX. If any problem is detected with the engine, the check engine light will turn on. To properly diagnose the issue, it is important to have a suitable scanner that is compatible with your car’s brand and model. The scanner will display the engine fault code that the computer has detected, which is related to a specific problem affecting the engine.
3. Worn Out Spark Plugs: Worn out spark plugs can lead to ignition problems, fuel wastage, and even damage other essential elements of your vehicle. If the spark plugs are worn out, they can trigger the check engine light.
4. Throttle Body Issues: In some cases, the check engine light may be related to throttle body issues. For example, there have been reports of a known manufacturing defect on the throttle body of the Acura RSX Type S, which may require replacement.
It’s important to note that the check engine light can indicate a wide range of problems, and it’s best to have a certified technician diagnose the issue for an accurate assessment and repair.
