What are the common causes of P0585 ?

• Some aftermarket accessories and performance modifications
• A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area.
• Defective ECU strategies or components will prevent proper regeneration

How do you troubleshoot P0585 ?

Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0585 code intake and exhaust valves. The lifters can be collapsed by disengaging an internal locking pin. The locking pin is disengaged using solenoids to alter oil pressure fed into the lifter.
