Default Re: Code 31, what's the impact of it? (2 problems actually)

Possible causes:
Faulty Ground
Faulty Connection
Bad ECM
Bad Cam Sensor
Right then, I have the manual and it says to check the ECU when running to see if a current is coming through (Brown plug, pin 3 from memory). Can I pull the whole 'Brown' plug when the engine is running though? or do I need to just take out pin 3?

The manual then says if there is a fluctuating current coming through it's your ECU that's the issue.

I'm hoping there's no current then as I'm guessing a sensor or connection is an easier fix. Anyhow I'll have a play around with it tomorrow.

Thanks for the info Jeff
