The P2716 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Pressure Control Solenoid “D” within the automatic transmission system of a vehicle. This code is triggered when the Powertrain Control Module (PCM) detects an electrical malfunction related to the solenoid responsible for regulating hydraulic pressure in the transmission. Proper functioning of the pressure control solenoid is crucial for smooth
The P0025 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the exhaust camshaft position timing on Bank 2 of the engine. Specifically, it signifies that the camshaft timing is excessively retarded compared to what the engine control module (ECM) has commanded. This condition can lead to various performance issues and may affect the overall efficiency of the vehicle. Understanding this
The P0412 trouble code is an OBD-II diagnostic code that indicates a malfunction in the Secondary Air Injection System (SAIS), specifically related to the switching valve circuit. This system plays a crucial role in reducing harmful emissions by injecting fresh air into the exhaust stream during cold starts, facilitating the oxidation of unburned hydrocarbons and carbon monoxide. When the Powertrain Control Module (PCM) detects an
The P0625 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the generator field or F terminal circuit within a vehicle’s electrical system. Specifically, it signifies that the powertrain control module (PCM) has detected a voltage signal from the generator field coil circuit that is lower than expected. This can lead to various issues, including battery charging problems and engine performance
The P2146 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel injector group “A” supply voltage circuit. Specifically, this code is triggered when the Engine Control Module (ECM) detects an open circuit in the voltage supply line for one or more fuel injectors in this group. This can lead to significant engine performance issues, including rough idling, stalling, and
The P0690 trouble code is an OBD-II diagnostic code that indicates a problem with the ECM/PCM (Engine Control Module/Powertrain Control Module) power relay circuit. Specifically, it signifies that the power relay sense circuit is reporting a high voltage condition. This can lead to various issues in vehicle performance, including starting problems and electrical system malfunctions. Understanding the P0690 code is essential for vehicle owners and
The P1065 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Control Module (ECM) power supply circuit. This code is primarily associated with Nissan and Infiniti vehicles but can also appear in other makes. When the P1065 code is triggered, it signifies that the ECM is not receiving the correct voltage from the battery or alternator, which can lead
The P2070 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the intake manifold tuning (IMT) valve, specifically that it is stuck open on bank 1 of the engine. This code is part of the OBD-II system, which monitors various components of the vehicle’s engine and emissions systems. When the powertrain control module (PCM) detects that the IMT valve has not
The P1189 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel control system, specifically related to fuel pressure monitoring. This code is often triggered when the Engine Control Module (ECM) detects a deviation in fuel pressure that could lead to engine performance issues. Understanding this code is crucial for vehicle owners and DIY mechanics, as it can lead to
The P203B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the “Reductant Level Sensor A Circuit Range/Performance.” This code is primarily associated with diesel engines equipped with a Diesel Exhaust Fluid (DEF) system. The DEF system is crucial for reducing harmful emissions, and the reductant level sensor plays a vital role in monitoring the fluid level in the DEF tank.
