P0012 – A Camshaft Position – Timing Over-Retarded (Bank 1)

Introduction

The P0012 error code on Chery is a fairly common issue that many drivers face.

The P0012 error code is associated with the camshaft position sensor, which plays a vital role in regulating engine timing. This sensor helps the Engine Control Module (ECM) determine when to inject fuel and ignite the spark plugs. The technical meaning of the P0012 code is that the camshaft position is over-retarded, indicating a problem with the camshaft position sensor or its circuit.

Common Chery Models Affected

The P0012 error code can affect various Chery models, including:

• Chery Tiggo
• Chery Arrizo
• Chery Fulwin
• Chery Cowin
• Chery Karry
