Hi all,
I have an 04 Impreza wagon 2.0L and have just had the EML light come on i have read the code and am getting codes for:

Intake valve control circuit, Engine oil temp sensor, Throttle control motor, throttle valve position limits, VVT timing system operation Bank 1 and bank 2, B+ via ignition switch, park neutral switch, communication with AT swirl control valve SCV and atmospheric pressure signal.

Hopefully someone maybe able to help, from the fact that there are so many faults stored and current most of these are secondary faults or they may all share a common earth or supply

Thanks
Steve

 

You've not had the gearbox out of the car recently. theres allot of fault codes in there. sounds like the gearbox earth strap if the box has been out, if not erase the codes. Take it for a run and see which ones come back to narrow down the faults

 

Yeah I checked all the earth point and they all seem to be fine, but none of the faults will clear down!

 

check the multi plugs behind the battery for corrosion etc seen that happen before
