What is P245A : Engine Error code Causes Explained
Engine trouble code P245A suggests diesel cooler bypass control circuit malfunction. This issue may influence engine emissions and efficiency. Knowing its causes, symptoms, and solutions helps prevent performance difficulties and pricey repairs.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P245A refers to an issue with the Diesel Particulate Filter (DPF) Pressure Sensor, specifically related to the performance of the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit.
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. Connect the scanner to the vehicle’s OBD-II port, typically located beneath the dashboard. The P245A code will appear if the system detects the issue, often accompanied by additional freeze-frame data that provides context on when and how the error was triggered.
Causes of P245A Error Code:
- Faulty EGR bypass valve:
Most common cause: valve fails to open/close, disrupting EGR cooler bypass. - EGR cooler problems:
EGR cooler blockages, leaks, or damage affect function, triggering code. - Damaged wiring or connectors:
Loose/corroded/broken EGR wires disrupt PCM signal, triggering code. - Faulty EGR temperature sensor.
Sensor monitors exhaust temperature, helping PCM control EGR cooler bypass. - Excessive carbon buildup:
Carbon buildup disrupts EGR valve and cooler tunction.
Risk Level of P245A Error Code:
When the error is classified as “High Risk Level,” it means the malfunction is severe enough to impact engine performance, fuel efficiency, or emissions compliance.
Immediate inspection and repairs are strongly recommended to prevent further damage and ensure vehicle safety.
Common Car Brands Affected by P245A Code:
The P245A engine error code is commonly found in the following list.
- Ford
- Volkswagen
- Jeep
- Chevrolet
- Ram
- RAM
- Mercedes
- Dodge
