The Best 2001 Honda Accord Check Engine Light Not Working 2023. The issue at that time was the coil packs. Web i was reading the honda manual and it clearly states the light should stay on for 20 seconds, which now has me worried that the cel might not be working properly and might put me in a bad situation if it doesn't alert me on something serious.

This means that the air and fuel being introduced to one of the cylinders is not completing a burn/combustion on its power stroke. Web driving home this evening, the check engine light just started flashing. Web plug a good scanner into the obd ii port.
