Code P2145 Description
The P2145 code refers to a problem with the Exhaust Gas Recirculation (EGR) vent control circuit being detected as too high. The EGR system helps reduce emissions by recirculating a portion of the engine's exhaust gas back into the combustion chamber. The vent control circuit is responsible for regulating the flow of exhaust gas in the EGR system. When this circuit malfunctions and registers a high voltage signal, it can lead to a variety of issues with the vehicle's performance.
Common Causes of P2145
- Damaged or corroded wiring in the EGR vent control circuit
- Faulty EGR valve
- Defective EGR solenoid
- Issues with the engine control module (ECM)
- Carbon buildup in the EGR system
