Trouble code P0446 is a diagnostic trouble code (DTC) that signifies a malfunction in the evaporative emission control (EVAP) system, specifically related to the vent control circuit. This code is triggered when the engine control module (ECM) detects a fault in the vent valve circuit, which can lead to improper functioning of the EVAP system.
The P1577 trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the vehicle’s electronic systems, specifically concerning the brake switch or the engine mount solenoid valve. This code is part of the OBD-II standard, which allows for the identification of faults within a vehicle’s engine and associated systems. Understanding this
The P0006 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel shutoff valve “A” control circuit. This code is primarily associated with vehicles equipped with advanced fuel delivery systems that utilize electronic control of the fuel shutoff valve. The fuel shutoff valve plays a crucial role in regulating the
The P0420 trouble code, also known as “Catalyst System Efficiency Below Threshold (Bank 1),” is a common diagnostic trouble code (DTC) that indicates an issue with the catalytic converter’s performance on the engine’s bank 1. This code is triggered when the vehicle’s onboard computer detects that the catalytic converter is not functioning efficiently, leading to
The P0611 trouble code is a diagnostic trouble code (DTC) that indicates a performance issue with the Fuel Injector Control Module (FICM). This code is primarily associated with vehicles equipped with electronic fuel injection systems, where the powertrain control module (PCM) detects that the FICM is not functioning as expected. When the PCM identifies a
The P1675 trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the vehicle’s electronic control system. Specifically, it often pertains to the evaporative emission control system, which is responsible for preventing fuel vapors from escaping into the atmosphere. When this code is triggered, it suggests that the vehicle’s onboard diagnostics
The P1462 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Air Conditioning (A/C) pressure sensor circuit. Specifically, it signifies that the signal voltage from the A/C pressure sensor is below a calibrated level, which can affect the vehicle’s climate control system and overall performance. Understanding this code is crucial
The P2219 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the NOx (Nitrogen Oxide) sensor heater control circuit in Bank 2 of a vehicle’s engine. This code is triggered when the Engine Control Module (ECM) detects a lower than expected voltage in the NOx sensor heater circuit. The NOx sensor
The P2518 trouble code is part of the On-Board Diagnostics II (OBD-II) system and specifically refers to an issue with the A/C Refrigerant Pressure Sensor “B” Circuit High. This code indicates that the Engine Control Module (ECM) has detected a high voltage condition in the circuit associated with the refrigerant pressure sensor. This can lead
The P007B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the charge air cooler temperature sensor circuit, specifically a range or performance problem in Bank 1. This code is typically associated with vehicles equipped with turbocharged engines that utilize a charge air cooler (also known as an intercooler) to enhance
The P0613 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction within the Transmission Control Module (TCM) processor. This code is typically triggered when the Powertrain Control Module (PCM) detects an issue with the TCM, which is crucial for regulating the automatic transmission’s shifting and performance. Understanding this code is essential for
