P0484 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. |
P0484 Possible Fix :
Detonation, or spark knock, is a type of combustion caused by the buildup of too much heat and pressure in the engine's combustion chamber. When this happens, you should be able to hear a metallic knocking or pinging noise. A small amount of detonation usually won't cause major damage, but heavy knocks or prolonged detonation can cause serious damage to your parts. It can punch holes in your pistons, crush rod bearings, blow head gaskets, crack rings, and pound out piston ring grooves. Prolonged pinging noises are a definite cause for concern.

Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed.
