Code P2147 Dodge Description
The P2147 diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the Cylinder 1 Injector High Control Circuit Low Voltage. This code indicates that there is a problem with the electrical circuit that controls the fuel injector for cylinder 1 in the engine. The fuel injector is responsible for delivering the precise amount of fuel into the combustion chamber for efficient combustion. When the control circuit voltage is too low, it can lead to improper fuel delivery, which can result in a variety of performance issues.
Common Causes of P2147 Dodge
- Wiring harness issues
- Faulty fuel injector
- Malfunctioning fuel injector driver module
- Problem with the engine control module (ECM)
- Corrosion or poor connections in the electrical system
