P0002 BMW Fault Code
Check P0002 OBD Fault Code ReasonVariable Cam Timing Over-advanced (Bank 1) The comprehensive component monitor (CCM) monitors the VCT position for an over-advanced camshaft timing.
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position.
BMW cam timing improperly set No oil flow to the VCT piston chamber Low oil pressure VCT solenoid valve stuck closed Camshaft advance mechanism binding (VCT unit) P0002 DTC is a check of the VCT unit.
P0002 Code Symptoms :
There are currently two main types of cylinder deactivation used today, depending on the type of engine. P0002 code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed.
Diagnosis And Repairing P0002
P0002 OBD 2 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.
How to fix P0002 code ?
- Erratic camshaft position due to low oil pressure
- Faulty Camshaft Position Sensor
- Faulty Camshaft Position Sensor
- Variable Camshaft Timing (VCT) position circuit poor electrical connection
Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P0002, so consult the manual to locate the brake fluid reservoir.
Bear in mind that a low fluid level can set code P0002 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
