Replace faulty sensors Defective oxygen, MAF, or temperature sensors should be replaced to restore accurate readings. PRESSURE SENSOR CIRCUIT, PARTICLE FILTER Symptoms: Limp Mode / Safe Mode (Low Power) Warning Lights: Check Engine Light - On Solution: DPF Removed and Software Re-Engineered to exclude DPF & EGR function from the Engine Control Unit (ECU). Learn the symptoms, tools, and steps to test a failed DPF pressure or temp sensor. 10 Common fault codes related to DPF problems, and how to deal with them. Professional DTC OFF for Bosch EDC17 in Renault diesel cars. Anyone have any ideas? P2428 Exhaust gas temp sensor 1 - High temp P144E Closed loop DPF. A low to moderate pressure differential indicates that the filter is clean and functioning properly. Aug 19, 2025 · Complete guide to diagnosing truck DPF sensor issues. This sensor plays a vital role in assessing the DPF's operational efficiency by monitoring the airflow resistance across the filter. A tired injector, a sensor fault, or a failed thermostat can start the chain. Blocked ECM-2A00 Pressure Sensor Particulate Trap. Faulty Signal ECM-2A30 Particulate Trap. This can indicate: True DPF restriction Sensor clogging Pressure tube blockage Water contamination Sensor voltage circuit fault Cracked pressure lines Without accurate pressure, the ECM cannot perform a regen. Mar 3, 2022 · Volvo S60 D5 DPF EGR Removal Fault Codes: ECM-2B40 Particulate Trap. The good news — most of these are DIY-fixable for under $200. These failures can prematurely force the engine into a reduced power mode, known as “limp mode,” to prevent catastrophic damage to the engine and the DPF itself. No Sub Type Information ECM-P246386 Diesel Particulate Filter Restriction - Soot Accumulation. Value ECM-28E0 Heated Oxygen Sensor (HO2S). 5 dCi DPF EGR Removal Fault Codes: P1453-64 DIFF. Clearing the DPF without fixing the root cause often means the same warning comes right back. Skipping this step can result in persistent fault codes and ineffective regeneration cycles, even with a new sensor installed. No more warning lights and original power restored. 1. Feb 25, 2026 · Expert Tip: When replacing a DPF pressure sensor on a Ford Transit or similar model, always use a compatible calibration tool to reset the ECU and initiate a system check.

This guide covers all 7 common issues with confirmed part numbers Feb 14, 2026 · Professional guide to diesel DPF differential pressure sensor diagnostics, cleaning vs replacing, and exhaust back pressure testing for Sprinter, Ram, and Ford Transit. If the DPF is clogged with soot, the sensor may register abnormal pressure levels, causing the system to trigger a fault. It does this by measuring the exhaust back pressure upstream and downstream of the DPF. ECM-2B30 Particulate Trap. Nov 19, 2025 · 🚨 What Does SPN 3055 Mean? SPN 3055 = DPF Differential Pressure Sensor Voltage Out of Range The ECM sees the wrong pressure reading across the DPF. Faulty Signal ECM-2BAA Particulate Trap. How To Treat Regeneration The Right Way Think of regen as a normal maintenance event the car handles on its own when conditions line up. P2002 - Diesel Particulate Filter Efficiency Below Threshold: This code indicates that the DPF is not functioning efficiently, likely due to excessive soot buildup. Signal Invalid Symptoms: Limp Mode / Safe Mode (Low Power) Warning Lights: Check Engine Light - On DPF Warning Light - On Mar 3, 2022 · Nissan Juke 1.
