The P1656 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction related to the Variable Valve Timing (VVT) system in various vehicle makes and models. This code can manifest in different ways depending on the specific vehicle, but it generally points to issues with the oil control valve (OCV) or camshaft timing. …
The P050B trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the ignition timing control system specifically during cold start conditions. This code is applicable to modern vehicles equipped with On-Board Diagnostics II (OBD-II) systems. When the powertrain control module (PCM) detects that it cannot properly control the ignition timing during …
The P1138 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel trim system, specifically related to the swirl control valve in vehicles equipped with this feature. This code typically arises when the Engine Control Module (ECM) detects that the target opening angle of the swirl control valve does not …
The P0037 code is a diagnostic trouble code (DTC) that indicates a problem with the heated oxygen sensor (HO2S) heater control circuit on Bank 1, Sensor 2. This code specifically points to a low voltage condition in the circuit, which can affect your vehicle’s fuel efficiency, emissions, and overall performance. P0037 Code Meaning P0037 Code …
The P1664 trouble code is an OBD-II diagnostic code that indicates a malfunction in the skip shift upshift lamp control circuit, primarily found in certain vehicles. This code typically arises when the vehicle’s Powertrain Control Module (PCM) detects a discrepancy between the commanded state and the actual state of the skip shift lamp during a …
The P1152 trouble code is an OBD-II diagnostic code that indicates a problem with the oxygen sensor circuit, specifically related to the fuel and air metering system. This code is typically associated with vehicles that have a dual-bank exhaust system, where each bank has its own oxygen sensor. The P1152 code suggests that the upstream …
The P0405 code is a diagnostic trouble code (DTC) that indicates an issue with the Exhaust Gas Recirculation (EGR) system in a vehicle. Specifically, it points to a problem with the EGR sensor A circuit, which is reporting a lower voltage than expected. This code is crucial for maintaining proper engine performance and emissions control, …
The P0683 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the glow plug preheating system in diesel engines. Specifically, it refers to a malfunction in the communication circuit between the glow plug control module and the powertrain control module (PCM). This code is crucial for diesel engine operation, especially in …
The P2A01 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically for Bank 1 Sensor 2. This code is applicable to all vehicles manufactured from 1996 onwards and signifies that the downstream oxygen sensor has failed to provide an acceptable signal to the powertrain control module …
The P030085 trouble code is a diagnostic code that indicates a random or multiple cylinder misfire has been detected in a vehicle’s engine. This code is part of the OBD-II (On-Board Diagnostics II) system and is typically triggered when the engine control module (ECM) detects an irregularity in the combustion process of one or more …
