What is P2452 : Engine Error code Causes Explained
This tutorial covers the P2452 engine trouble code, its causes, its diagnosis and repair. Maintaining engine performance and avoiding costly repairs requires understanding this code.
How to Identify a DTCs Number
The P2452 engine error code refers to an issue with the diesel particulate filter (DPF) pressure sensor 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 (Diagnostic Trouble Code) number, you can use an OBD-II scanner to scan the vehicle’s onboard diagnostic system. The scanner will retrieve the DTC associated with any malfunctions in the vehicle. You can connect the scanner to the vehicle’s OBD-II port, typically found under the dashboard, near the driver’s seat, and follow the instructions provided with the scanner to retrieve and identify the code.
Causes of P2452 Error Code:
- Faulty Diesel Particulate Filter pressure sensor (DPF):
The sensor itself could be defective, not sending accurate pressure readings. - Wiring Issues:
Damaged or corroded wires in the DPF pressure sensor circuit can lead to incorrect signals. - Clogged Diesel Particulate Filter pressure sensor (DPF):
If the DPF is excessively filled with soot, it can cause high pressure and trigger the code. - Exhaust leaks:
Leaks in the exhaust system upstream or downstream of the DPF can affect pressure readings. - Diesel Exhaust Fluid (DEF) issues:
In some vehicles, a low DEF level can trigger this code.
Risk Level of P2452 Error Code:
A medium risk level associated with this error indicates that while the problem may not be immediately detrimental, it can lead to performance issues and potential engine damage if not addressed. It’s best to diagnose and repair the issue as soon as possible.
Common Car Brands Affected by P2452 Code:
The P2452 engine error code is commonly found in the following list.
- Ford
- Volkswagen
- Dodge

FAQ’s
What is the P2452 engine error code?
The P2452 engine error code indicates a problem with the Diesel Particulate Filter (DPF) pressure sensor, which is responsible for monitoring the filter’s pressure levels. This code points to an issue with sensor readings or the DPF system.
What causes the P2452 engine error code?
The causes of the P2452 error can include a faulty DPF pressure sensor, wiring issues, or a malfunctioning exhaust system. It may also result from an overly clogged DPF, which restricts airflow and causes incorrect sensor readings.
What is the risk level of the P2452 engine error code?
The risk level of the P2452 error code is considered medium. If unresolved, it could lead to a reduction in vehicle performance, poor fuel economy, or further damage to the DPF system.
Which vehicles are affected by the P2452 engine error code?
The P2452 engine error code is commonly found in diesel-powered vehicles like Ford, Dodge, and Volkswagen, depending on their emissions systems.
