What is P245C : Engine Error code Causes Explained
The diesel particulate filter (DPF) coolant bypass valve is stuck closed; the engine fault number is P245C. Exhaust aftertreatment efficiency may decrease, increasing emissions and engine performance.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P245C is related to the Diesel Particulate Filter (DPF) Pressure Sensor and is often associated with the Exhaust Gas Recirculation (EGR) system.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify a DTC’s number, you need an OBD-II scanner. By connecting it to the vehicle’s OBD-II port (usually located under the dashboard), you can retrieve the error code stored in the vehicle’s computer. The scanner will display P245C along with possible descriptions and freeze-frame data, helping diagnose the root cause of the issue.
Causes of P245C Error Code:
- Faulty EGR Cooler Bypass Valve:
Main issue: valve stuck open/closed, blocking EGR cooler bypass. - Clogged EGR Cooler.
Carbon buildup restricts exhaust flow, reducing EGR cooler efficiency, triggering code. - Defective EGR Cooler Temperature Sensor.
Faulty EGR temp sensor disrupts bypass valve regulation. - Damaged Wiring or Connectors:
Broken/corroded wires in EGR bypass circuit disrupt ECM-valve communication. - Malfunctioning ECM:
Faulty ECM sends incorrect signals to EGR bypass vlive.
Risk Level of P245C Error Code:
A high-risk level for this code means that the engine’s emissions system is not functioning correctly, potentially leading to increased soot accumulation, reduced fuel efficiency, and even engine damage if left unaddressed.
Ignoring this code can lead to expensive repairs or even complete engine failure, so it’s best to diagnose and fix the issue as soon as possible.

FAQ’s
What is the P245C Error Code?
The P245C code indicates a problem with the Diesel Particulate Filter (DPF) coolant bypass valve, specifically that it is stuck in the closed position.
What Causes the P245C Error Code?
Causes include a faulty DPF coolant bypass valve, electrical wiring issues, corrosion, or a malfunction in the engine control module (ECM).
What is the Risk Level of This Code?
The risk level is high, as it can cause improper DPF cooling, leading to overheating, increased emissions, and potential engine performance issues.
Which Vehicles Are Affected by This Code?
This code typically affects diesel-powered vehicles equipped with a DPF system, including models from Ford, Volkswagen, Jeep, Chevrolet, Ram, Mercedes and Dodge.
