Title: Confused....emission code 0443.
Post by: sandune on 03 February 2010, 20:37:05

Had the emission lit for three days.
 Pedle tricked ..got 0433 ,this seems to have three possible faults.
  1- emission evaporative system-purge control valve circuitshorted.
  2- emission evaporative system-control valve circuit open.
  3-evaporative emission control system gross leak detected.
 So which of the three is true as the light is now normal again?

Auto Data Trouble Codes Book Says:

P0433 Heated Catalytic Converter,bank 2- efficiency below Threshold...
Probable cause:
Catalytic converter, wiring, HO2S 2 (heated oxygen sensor)

I think you've just quoted an 0430

The OP is correct in his reading ..  :y :y :y

Unfortunately I have no idea what the cause might be ... MarkDTM might pass by soon .. he is sure to know .. :)

If it's 443 it's potentially an easy one. Evap. Emission purge valve is a little black solenoid valve just behind the driver's side cylinder head. One of the smaller 2 pipes from the black breather housing on the plenum goes to it, and then in to the driver's side wing. You can probably find it by following the pipes.

Erro is complaining that the circuit is open, so possibly connector on this solenoid is loose or coil has gone open circuit.
