Check P2321 Fault Code

When you check engine light came on code P2321 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P2321 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P2321 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.

P2321 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.

P2321 OBD-II Diagnostic Powertrain (P) Trouble Code Description P2321 OBD-II Trouble Code The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Each cylinder is equipped with 1 dual-output coil. Meaning one coil mounts directly over one of the dual spark Reason For P2321 Code The reason of P2321 OBD-II Fault Code Check is P2321 Ignition Coil 7 Circuit Low.

P2321 Solution:

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. Observe PSP V PID while checking wires for intermittents.

How to Clear P2321 Trouble Code

An OBD 2 scanner is the best and safest way to erase a DTC from your car's system. This scanner communicates with the car's computer and instructs the computer to erase the code. It does not change or tweak the settings from inside the car or its systems.
