* Different Systems: The power steering system and the engine control system are largely independent. The CEL is triggered by sensors monitoring engine-related issues like fuel delivery, emissions, and engine performance.
* Leak Detection: While a significant power steering leak could lead to low fluid levels and potentially affect the steering feel, it doesn't directly impact the engine control system's sensors.
However, there are some indirect connections to consider:
* Low Fluid Level: A severe power steering leak could lead to very low fluid levels. If the pump is drawing in air, it might cause the engine to run rough, which *could* trigger the CEL.
* Electrical Fault: A power steering leak could be caused by a faulty power steering pump or hose. If there is an electrical malfunction within the pump, it might throw a code related to the power steering system. This code might be displayed as a check engine light in some vehicles.
If your check engine light is on, it's best to get it diagnosed:
* OBD-II Scanner: Use an OBD-II scanner to read the trouble codes stored in the vehicle's computer. This will pinpoint the specific issue that triggered the light.
* Mechanic: Consult a qualified mechanic who can diagnose the issue and recommend the necessary repairs.
Remember: A power steering leak is a separate concern that needs to be addressed regardless of the check engine light status. It's crucial to maintain adequate power steering fluid levels for proper vehicle handling and safety.
