The P21DD trouble code is an OBD-II diagnostic code that indicates a problem with the reductant heater circuit in diesel engines, particularly those equipped with a diesel exhaust fluid (DEF) system. This code specifically signifies that the current to the reductant heater ‘A’ is too low, which can lead to issues with the vehicle’s emissions

The P0717 trouble code, defined as “Input/Turbine Speed Sensor ‘A’ Circuit No Signal,” indicates that the powertrain control module (PCM) has detected a failure in the input speed sensor circuit. This sensor plays a critical role in monitoring the transmission input speed, which is essential for proper vehicle operation. When the PCM does not receive

The P0120 trouble code is a diagnostic trouble code (DTC) that signifies a malfunction in the Throttle Position Sensor (TPS) or its circuit. This code is triggered when the Powertrain Control Module (PCM) detects an abnormal voltage signal from the TPS, which is responsible for monitoring the position of the throttle valve. The TPS plays

The P0032 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the heater control circuit of the oxygen sensor located in Bank 1, Sensor 1. This code is part of the OBD-II system, which monitors the performance of the engine and its components. When this code is triggered, it typically means

The P0234 trouble code is a diagnostic trouble code (DTC) that indicates an overboost condition in the turbocharger or supercharger system of a vehicle. This code is triggered when the engine control module (ECM) detects that the boost pressure exceeds the manufacturer’s specified limits, which can lead to serious engine damage if not addressed promptly.

The P0328 trouble code indicates a problem with the knock sensor circuit, specifically a high input voltage from the knock sensor on bank 1 of the engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s engine and transmission. The knock sensor plays a crucial role

The P2006 code is a diagnostic trouble code (DTC) that signifies an issue with the intake manifold runner control (IMRC) system, specifically indicating that the IMRC actuator for engine bank 1 is stuck in the closed position. This malfunction can lead to reduced engine performance and efficiency, as the IMRC system plays a crucial role

The P2106 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Throttle Actuator Control System, specifically signaling that the system has been forced into a limited power mode. This occurs when the Engine Control Module (ECM) detects an issue that could potentially harm the engine or transmission, leading to reduced

The P0330 trouble code indicates a malfunction in the Knock Sensor 2 Circuit for Bank 2 of the engine. This diagnostic trouble code (DTC) is part of the OBD-II system and is triggered when the Engine Control Module (ECM) detects an issue with the knock sensor’s operation, which is crucial for monitoring engine knocking and

The P015B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor in your vehicle. Specifically, it signifies a delayed response from the upstream oxygen sensor (Bank 1, Sensor 1) in the engine’s exhaust system. This sensor plays a critical role in monitoring the air-fuel mixture by measuring the

The P2187 trouble code is a diagnostic trouble code (DTC) that indicates the engine control module (ECM) has detected a lean air-fuel mixture at idle in bank 1 of the engine. This means that there is too much air and not enough fuel being delivered to the engine during idle conditions, which can lead to
