PROBLEMS — WARNING LIGHTS
Check engine light on?
The check engine light means the engine control unit has detected a fault. A steady light should be checked soon; a flashing light usually means a misfire — reduce speed and get it checked promptly.
Why the code isn't the answer
01
Codes point to systems
A sensor code can be caused by wiring, a leak or another component.
02
Test the circuit
We check power, ground and signal before condemning a part.
03
Confirm & clear
After repair we verify the light stays off under the same conditions.
Questions owners ask
- Can I just clear the code?
- Clearing it hides the symptom; the fault usually returns. Find the cause first.
