The P0370 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the timing reference high-resolution signal “A.” This code is primarily associated with the crankshaft position sensor and is set when the Powertrain Control Module (PCM) detects an issue with the signal that is essential for accurate engine timing and synchronization. …
The P1148 code is a diagnostic trouble code (DTC) that indicates a problem with the closed loop control function of the Bank 1 air/fuel ratio sensor. This code is commonly found in Nissan and Infiniti vehicles, but can also appear in other makes. When the engine control module (ECM) detects that the closed loop control …
The P0046 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Turbocharger/Supercharger Boost Control “A” Circuit Range/Performance. This code is logged when the Powertrain Control Module (PCM) detects that the boost control solenoid is not functioning within its expected parameters. The boost control system plays a crucial role in managing …
The P050A trouble code is a diagnostic trouble code (DTC) that indicates a problem with the cold start idle control system performance. Specifically, it refers to the Powertrain Control Module (PCM) being unable to maintain the desired engine RPM during cold starts. This is crucial for ensuring that the engine runs smoothly and efficiently when …
The P1380 trouble code is a manufacturer-specific diagnostic code that generally indicates a problem with the vehicle’s Variable Cam Timing (VCT) system or a misfire detection issue. This code is commonly found in Ford, GM, and Toyota vehicles, though its exact meaning can vary between manufacturers. When this code appears, it often signals a malfunction …
The P0563 trouble code indicates a high voltage issue within a vehicle’s electrical system. This code is triggered when the Powertrain Control Module (PCM) detects a voltage reading that exceeds the manufacturer’s specified limits. Such high voltage can lead to various operational issues, affecting everything from engine performance to electrical accessory functionality. Understanding and addressing …
The P2768 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Input/Turbine Speed Sensor “B” circuit. This code is set when the Powertrain Control Module (PCM) detects an intermittent signal from the input or turbine speed sensor, which is crucial for monitoring the transmission’s input speed. An erratic signal can …
The P0628 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the fuel pump ‘A’ control circuit, specifically indicating a low voltage condition. This code is part of the OBD-II system, which monitors various components of the vehicle’s powertrain, including the engine and transmission. When the Powertrain Control Module (PCM) detects …
The P0145 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically a slow response from the downstream oxygen sensor located in Bank 1, Sensor 3. This code is logged when the powertrain control module (PCM) detects that the oxygen sensor is not responding quickly enough to …
The P2296 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel pressure regulator control circuit. Specifically, it signifies that the Powertrain Control Module (PCM) has detected a high voltage signal from the electronic fuel pressure regulator designated as “2.” This code is applicable to various OBD-II equipped vehicles, including …
