OBD-II Diagnostic Trouble Code P20E9: Reductant Pressure Too High The P20E9 diagnostic trouble code (DTC) indicates that the reductant pressure in the vehicle's Selective Catalytic Reduction (SCR) system is higher than the manufacturer's specified range. This code is primarily associated with diesel engines equipped with SCR technology for reducing nitrogen oxide (NOx) emissions. In our
Understanding the P20EE Code: Causes, Diagnosis, and Repair The P20EE code indicates that the Selective Catalytic Reduction (SCR) NOx catalyst efficiency is below the acceptable threshold for bank 1. This code is considered a severe issue, with a DTC severity of 3 out of 3, meaning you should stop and repair the vehicle immediately. In
The P226D code indicates a problem with the particulate trap reduction functionality in bank 1 of your vehicle’s emission control system. This code specifically relates to the diesel particulate filter (DPF), which is responsible for reducing emissions from the exhaust by trapping and burning off particulate matter. The code suggests that there may be an
Understanding the P2100 Engine Code: Causes, Diagnosis, and Repair The P2100 code, which stands for "Throttle Actuator Control Motor Circuit/Open", is a generic powertrain code that indicates an electrical issue with the throttle actuator control (TAC) motor circuit. This code is triggered when the powertrain control module (PCM) detects an open circuit in the TAC
The OBD-II diagnostic trouble code P20E8 indicates a problem with the reductant pressure in the vehicle's urea injection system, specifically that the pressure is too low for normal operation. This article provides an in-depth analysis of the P20E8 code, its implications, and how to diagnose and repair the issue. In our workshop, we've seen the
Welcome to our article on the P20E6 error code, which indicates a degradation in the efficiency of the Selective Catalytic Reduction (SCR) system’s NOx catalyst. This error code is associated with the emission control system in diesel engines and specifically the NOx reduction technology. When this error code appears, it signifies that the SCR NOx
The P20E5 trouble code relates to the exhaust gas temperature being low for the selective catalytic reduction (SCR) system. This code specifically affects the emission control system in diesel vehicles and the exhaust gas temperature. The SCR system utilizes DEF (diesel exhaust fluid) to reduce NOx emissions in the exhaust gas. When the exhaust gas
Welcome to our article on the P20DC error code related to the excess NH3 storage selective catalytic reduction (SCR) catalyst. In this section, we will explore the details of this error code and its impact on the performance of the SCR system and catalyst. Key Takeaways P20DC error code relates to the performance of the
The P20B7 error code, also known as the Reductant Injection Valve Circuit Low, is a common issue in the vehicle’s diesel exhaust system. This code is part of the vehicle emission control system and indicates a fault in the reductant injection valve, responsible for injecting diesel exhaust fluid (DEF) into the selective catalytic reduction (SCR)
Welcome to our article on the P20B6 fault code – Reductant Injection Valve Circuit High. In this article, we will explore what this code means, its impact on the diesel emission system and engine performance, and how it can be diagnosed and repaired. Whether you are a vehicle owner experiencing this issue or a technician
