Check Engine Light
NOTE:
Not all trouble codes activate CHECK ENGINE LIGHT.
All models are equipped with a CHECK ENGINE light. As a bulb check, light glows when ignition is turned on and engine is not running.
On California models, CHECK ENGINE light glows when a fault is detected with engine running. A corresponding trouble code will set in ECU memory. CHECK ENGINE light also glows if ECU or crank angle sensor malfunctions.
On Federal models, CHECK ENGINE light glows only when ECU or crank angle sensor malfunctions with engine running.
