What is P2454 : Engine Error code Causes Explained
The P2454 engine trouble number indicates a low DPF Pressure Sensor “A” circuit. This tutorial will explain its origins, symptoms, and treatments to preserve your vehicle’s performance and emissions system.
How to Identify a DTCs Number
The P2454 Diagnostic Trouble Code (DTC) indicates an issue with the Diesel Particulate Filter (DPF) Pressure Sensor Circuit – Low Voltage.
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.
This error typically occurs due to a faulty DPF pressure sensor, clogged or damaged pressure sensor hoses, exhaust leaks, wiring issues, or a malfunctioning PCM.
Causes of P2454 Code:
- Faulty sensor:
The exhaust differential pressure sensor may be faulty or have failed. - Circuit issues:
There may be an open or short circuit in the sensor circuit, or the connector may be loose. - Hoses or tubes:
The DPF pressure sensor hoses or tubes may be choked. - Incorrect fluid:
The diesel exhaust fluid may be incorrect. - Reservoir.
The diesel exhaust fluid reservoir may be empty.
Risk Level of P2454 Error Code:
A Medium Risk Level means the issue isn’t critical but can lead to reduced engine performance, poor fuel efficiency, or eventual DPF clogging if ignored.
If this code appears, it’s advisable to diagnose and repair the issue soon to prevent further complications.
Common Car Brands Affected by P2454 Code:
The P2454 engine error code is commonly found in the following list.
- Ford
- Audi
- Jeep
- Toyota
- GMC
- Mercedes-Benz

FAQ’s
What is P2454 Engine Error Code?
The P2454 code indicates a low voltage issue in the Diesel Particulate Filter (DPF) Pressure Sensor Circuit. This sensor monitors exhaust pressure to ensure proper DPF function.
What Causes the P2454 Error Code?
Common causes include a faulty DPF pressure sensor, damaged wiring, clogged DPF, or ECM issues. Moisture or corrosion in sensor connections can also trigger this code.
What is the Risk Level of P2454?
The risk level is medium. While the vehicle may still run, ignoring this issue can lead to reduced engine performance, increased emissions, or potential DPF failure.
Which Vehicles are Affected by P2454?
P2454 is commonly found in diesel vehicles, including Ford, Audi, Jeep, Toyota, GMC and Mercedes-Benz and other models with a Diesel Particulate Filter (DPF) system.
