What does this fault code mean?
This code concerns ignition timing control during a cold start, when the engine control module requests heating of the catalytic converter. If the ignition cannot be controlled as intended, the catalytic converter heats up too slowly, which can worsen emissions. Such a fault probably also stops idle control from working as it should. It is an information code that never appears alone, so troubleshooting starts with the other code.
