What is P2455 : Engine Error code Causes Explained
This tutorial covers the P2455 engine error code, its causes, and solutions. Understanding this code keeps your vehicle’s exhaust system running smoothly and prevents problems.
How to Identify a DTCs Number
The P2455 engine error code refers to a Diesel Particulate Filter (DPF) pressure sensor circuit range/performance issue.
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 the Diagnostic Trouble Code (DTC) number for a specific engine error, you would typically use an OBD-II scanner. By connecting the scanner to your vehicle’s OBD-II port, you can retrieve the DTC, which will be displayed on the device.
Causes of P2455 Error Code:
- Faulty Diesel Particulate Filter pressure sensor (DPF):
Faulty sensor sending incorrect high voltage to the engine computer. - Damaged Sensor Wiring:
Broken or corroded wire causing open/short circuit and high voltage reading. - Clogged Diesel Particulate Filter pressure sensor (DPF):
Clogged DPF causes excessive pressure, leading to high sensor reading. - Incorrect Sensor Connections:
Loose or improperly connected wires at the sensor can disrupt the signal. - Electrical Issues:
Short circuit in wiring causes signal wire to touch power, triggering code.
Risk Level of P2455 Error Code:
A “Medium Risk Level” indicates that while the problem may not immediately impact your vehicle’s operation, it could lead to performance issues or reduced fuel efficiency over time.
If this code appears, it’s advisable to diagnose and repair the issue soon to prevent further complications.

FAQ’s
What is the P2455 engine error code?
The P2455 engine error code indicates an issue with the Diesel Particulate Filter (DPF) temperature sensor. It suggests that the sensor is malfunctioning or providing incorrect readings of the exhaust temperature related to the DPF.
What causes the P2455 engine error code?
The P2455 error is typically caused by a faulty DPF temperature sensor, wiring issues, or a clogged DPF. In some cases, it can also be triggered by an exhaust system issue or incorrect sensor readings due to high temperatures.
What is the risk level of the P2455 engine error code?
The P2455 error code carries a medium risk level. If ignored, it may lead to reduced engine performance, poor fuel efficiency, and potential damage to the DPF system, which could result in costly repairs.
Which vehicles are affected by the P2455 engine error code?
The P2455 code is typically found in diesel vehicles with a DPF system. It can affect various makes and models, especially those from manufacturers like Ford, Volkswagen, Mercedes, Chevrolet, Dodge, Mazda and GMC depending on their diesel engine configurations.
