* Restricted Fuel Flow: A clogged fuel filter restricts the flow of fuel to the engine. This can lead to insufficient fuel supply, causing the engine to run poorly.
* Engine Misfire: Insufficient fuel delivery can lead to engine misfires. The engine control unit (ECU) detects these misfires and activates the "reduced engine power" light as a safety measure to prevent further damage.
* Fuel Pressure Issues: A clogged filter can also affect fuel pressure, which is crucial for proper engine operation. Low fuel pressure can contribute to poor engine performance and trigger the warning light.
Other Symptoms of a Bad Fuel Filter:
* Engine Hesitation: The engine may hesitate or struggle to accelerate.
* Rough Idle: The engine may idle rough or stall.
* Decreased Fuel Economy: You may notice a drop in fuel efficiency.
* Engine Stalling: In severe cases, the engine may stall completely.
Important Note: While a bad fuel filter is a possible cause, other issues can also trigger the "reduced engine power" light. It's crucial to have your vehicle diagnosed by a mechanic to determine the root cause and ensure the problem is resolved correctly.
