Yes the engine light is on now but the main problem is a knocking noise when the key isn't even in the ignition, just touch the car or just walk past it and it starts knocking! Any idea which sensor needs changing?
Vehicle:
Chevrolet 2008 Impala LT 3.5 liter

Hi there,
This code is for a faulty ignition switch. If the switch is shorting out that could be causing the problem. Otherwise you may have an issue with the theft control or body control module.
