The P0153 trouble code is a diagnostic code related to the oxygen sensor circuit in your vehicle. Specifically, it indicates a slow response from the oxygen sensor located in Bank 2, Sensor 1 position. This code is crucial for maintaining proper fuel efficiency and emissions control in your vehicle. P0153 Code Meaning P0153 Code Common …
The P1491 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Exhaust Gas Recirculation (EGR) valve in vehicles. Specifically, it signifies that the EGR valve lift is insufficient, meaning that the Engine Control Module (ECM) has detected that the EGR valve is not moving to the expected position when commanded. …
The P1123 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Throttle Position Sensor (TPS) in a vehicle’s engine management system. Specifically, it signifies that the TPS is reporting a voltage that is higher than expected while still being within its operational range. This discrepancy can lead to various performance …
The P0480 trouble code, also known as “Cooling Fan 1 Control Circuit Malfunction,” is a diagnostic code that indicates an issue with the cooling fan system in your vehicle. This code is triggered when the Powertrain Control Module (PCM) detects improper voltage or feedback from the cooling fan control circuit. Left unresolved, it can lead …
The P203C trouble code is a diagnostic code indicating an issue with the reductant level sensor circuit, specifically a low electrical reading. This sensor is part of the Diesel Exhaust Fluid (DEF) system in diesel-powered vehicles, which helps reduce emissions by monitoring DEF levels. A malfunction in this system can lead to emission non-compliance and …
The P1601 trouble code is an OBD-II diagnostic trouble code that indicates a communication error between the Engine Control Unit (ECU) and other critical components, such as the Transmission Control Module (TCM). This code can trigger various symptoms, affecting vehicle performance and drivability. Understanding the causes, symptoms, and repair methods for the P1601 code is …
The P0899 trouble code is a diagnostic code that indicates a problem within the transmission control system, specifically regarding the Malfunction Indicator Lamp (MIL) request circuit. This code is triggered when the Transmission Control Module (TCM) detects a high voltage condition in the MIL request circuit, which is responsible for signaling any transmission-related issues to …
The P2304 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the ignition coil ‘B’ primary control circuit, specifically a high voltage condition. This code is part of the OBD-II system, which monitors various components of a vehicle’s powertrain. When the powertrain control module (PCM) detects that the voltage in the …
The P052B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the camshaft position timing, specifically noting that it is “over-retarded” during cold start conditions on Bank 1 of the engine. This code is triggered when the Powertrain Control Module (PCM) detects that the camshaft timing does not align with its …
The P1390 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the timing belt or the relationship between the camshaft and crankshaft position sensors. This code is prevalent in various vehicles and typically points to issues such as a skipped timing belt tooth or problems with the throttle/pedal position sensor circuit. …
