The most common cause of this code is damage to wiring caused by wildlife. The warm area atop the engine provides shelter for small animals, where they proceed to gnaw the wiring for some strange reason. Other causes include a faulty fuel injector, clogged fuel injector, corroded or loose electrical wiring or connector faces, or a faulty fuel injector driver in the PCM. How do you troubleshoot P0281 ? Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0281 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.
