Trouble Codes

Hi guys,

Engine light just came on, engine hasn't changed and still runs smooth.

Error codes:

P0403 -- powertrain / exhaust gas recirculation control circuit

P0325 -- powertrain / knock sensor 1 circuit ( bank 1 or single sensor)

P0460 -- fuel sensor circuit

After looking up the codes it says ignition system or misfire.

Could this be the culprit to my intermittent startup issues?

Also does 'knock sensor' mean lamb sensor? Where is this located. I also thought only disels have egr's yet P0403 says egr.

    I think the lambada sensor is the the exhaust behind the cat, but this issue seems to be referencing different things.

    Could be one sensor throwing all of them wonky, but I couldnt tell you where to start!

    Dont believe they do, I would start by looking at the exhaust sensors, check when the CAT was last replaced, because it could well be the problem, my money is on a duff lambda sensor to be honest, so if you know someone who can, get that checked out first!
