Car troubles due to the MINI P0012 Code can be very frustrating and time-consuming to diagnose and repair. The MINI P0012 Code is a specific code used to identify an “A” Camshaft Position Over-Retarded (Bank 1) issue in an engine. This code is triggered when the engine is running at an engine speed of more than 400rpm, and the DME detects the camshaft timing exceeded the minimum calibrated retarded value or the camshaft remained in an retarded position during the CCM test. The common causes of the MINI P0012 Code are a failed fuel pump, CPS circuit open, shorted to ground, or shorted to power, battery voltage below 11.5 volts, position actuator circuit short to B+ or Ground, camshaft timing improperly set, or continuous oil flow to the VCT piston chamber, camshaft advance mechanism (the VCT unit) sticking or binding mechanically, and VCT solenoid valve attached in open position. With the right solutions and solutions, motorists can easily identify and repair issues related to the MINI P0012 Code.
Causes and Solutions to MINI P0012 Code
| Cause | Solution |
|---|---|
| Failed Fuel Pump | Replace the fuel pump, check the fuel pump relay and fuse |
| CPS Circuit is Open, Shorted to Ground, or Shorted to Power | Diagnose and repair short or open circuit |
| Battery Voltage Below 11.5 Volts | Replace the battery or charge the battery |
| Position Actuator Circuit May Short to B+ or Ground | Check and repair faulty wiring and connections |
| Camshaft Timing Improperly Set | Rebuild or replace the VCT unit |
| Continuous Oil Flow to the VCT Piston Chamber | Replace VCT unit |
| Camshaft Advance Mechanism (the VCT unit) Sticking or Binding Mechanically | Check and repair mechanical binding |
| VCT Solenoid Valve Stuck in Open Position | Replace the VCT solenoid valve |
When diagnosing a car’s engine, the MINI P0012 Code is one of the most common codes that can appear. This code is triggered when the engine is running at an engine speed of more than 400rpm, and the DME detects the camshaft timing exceeded the minimum calibrated retarded value or the camshaft remained in an retarded position during the CCM test. Common causes of the MINI P0012 Code can include a failed fuel pump, CPS circuit open, shorted to ground, or shorted to power, battery voltage below 11.5 volts, position actuator circuit short to B+ or Ground, camshaft timing improperly set, or continuous oil flow to the VCT piston chamber, camshaft advance mechanism (the VCT unit) sticking or binding mechanically, and VCT solenoid valve stuck in open position. Understanding the causes and solutions to the MINI P0012 Code can help motorists quickly identify and repair the issue, saving time and money.
Failed Fuel Pump
A failed fuel pump is a common cause of the MINI P0012 Code. If the fuel pump is not working properly, it can cause the engine to run poorly and trigger the code. The solution to this problem is to replace the fuel pump and check the fuel pump relay and fuses to ensure they are in good condition.
CPS Circuit Open, Shorted to Ground, or Shorted to Power
The CPS (Crankshaft Position Sensor) circuit can be open, shorted to ground, or shorted to power, causing the MINI P0012 Code. To diagnose and repair this issue, it is important to check for faulty wiring and connections and replace damaged components.

Battery Voltage Below 11.5 Volts
If the battery voltage is below 11.5 volts, it can cause the MINI P0012 Code. The solution is to replace or charge the battery if it is not completely dead.
Position the Actuator Circuit Short to B+ or Ground
The position actuator circuit can short to B+ or ground, which can cause the MINI P0012 Code. To fix this problem, it is important to check and repair any faulty wiring and connections.
Camshaft Timing Improperly Set
If the camshaft timing is incorrectly set, it can cause the MINI P0012 Code. The solution is rebuilding or replacing the VCT (Variable Camshaft Timing) unit.
Continuous Oil Flow to the VCT Piston Chamber
Continuous oil flow to the VCT piston chamber can cause the MINI P0012 Code. To repair this problem, it is important to replace the VCT unit.
Camshaft Advance Mechanism (the VCT unit) Sticking or Binding Mechanically
If the camshaft advance mechanism (the VCT unit) is sticking or binding mechanically, it can cause the MINI P0012 Code. It is important to check and repair any mechanical binding to fix this issue.
VCT Solenoid Valve Stuck in Open Position
If the VCT solenoid valve is stuck in an open position, it can cause the MINI P0012 Code. To repair this issue, replacing the VCT solenoid valve is important.
Conclusion: Quick Solutions to MINI P0012 Code
Encountering the MINI P0012 Code can be stressful and time-consuming, but with the right solutions and solutions, motorists can easily identify and repair issues related to the code. Common causes of the MINI P0012 Code include a failed fuel pump, CPS circuit open, shorted to ground, or shorted to power, battery voltage below 11.5 volts, position actuator circuit short to B+ or Ground, camshaft timing improperly set, or continuous oil flow to the VCT piston chamber, camshaft advance mechanism (the VCT unit) sticking or binding mechanically, and VCT solenoid valve stuck in open position. With the right knowledge and solutions, motorists can quickly fix the MINI P0012 Code and return to the road.
