The P0026 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Intake Valve Control Solenoid Circuit Range/Performance for Bank 1. This code is primarily associated with vehicles equipped with Variable Valve Timing (VVT) systems, which optimize engine performance and efficiency by adjusting the timing of the intake and exhaust valves. …
The P2059 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Reductant Injection Air Pump Control Circuit/Open. This code is primarily associated with diesel engines equipped with selective catalytic reduction (SCR) systems, which are designed to reduce nitrogen oxide (NOx) emissions. When the powertrain control module (PCM) detects an open …
The P1C4E trouble code is a diagnostic trouble code (DTC) that indicates a communication issue between the Engine Control Module (ECM) and the Steering Angle Sensor Module in vehicles, particularly those manufactured by Chrysler, Dodge, and Jeep. This code typically triggers the check engine light and can lead to various performance issues if not addressed …
The P0660 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Intake Manifold Tuning Valve Control Circuit for Bank 1. This code is generated when the Powertrain Control Module (PCM) detects a malfunction in the electrical circuit that controls the intake manifold tuning valve. The intake manifold tuning valve plays …
The P2105 trouble code is an OBD-II diagnostic trouble code that indicates a malfunction in the Throttle Actuator Control System, specifically signaling a forced engine shutdown. This code is critical because it can lead to significant performance issues, including the vehicle entering a “limp mode” where acceleration is severely limited. Understanding and addressing this issue …
The P2794 trouble code, also known as “Gear Shift Direction Circuit Low,” is a diagnostic code related to the transmission system in vehicles equipped with automatic transmissions. This code indicates that the Engine Control Module (ECM) or Transmission Control Module (TCM) has detected a low voltage condition in the gear shift direction circuit. Understanding and …
The P0060 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the heater circuit of the downstream oxygen sensor, specifically for Bank 2, Sensor 2. This code is generated by the Powertrain Control Module (PCM) when it detects that the electrical resistance in the heater circuit of the oxygen sensor exceeds …
The P16BB trouble code is a diagnostic trouble code (DTC) that indicates an issue with the alternator’s B terminal circuit, specifically related to low voltage. This code is often seen in Honda and Acura vehicles but can also appear in other makes that utilize similar electrical systems. When the powertrain control module (PCM) detects a …
The P0389 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Crankshaft Position Sensor ‘B’ circuit. This code is triggered when the Powertrain Control Module (PCM) detects an intermittent or erratic voltage signal from the secondary crankshaft position sensor. The crankshaft position sensor plays a crucial role in monitoring the …
The P204F trouble code is a diagnostic trouble code (DTC) that indicates a problem with the reductant system performance on engine bank 1 in vehicles equipped with a Selective Catalytic Reduction (SCR) system. This code typically arises in diesel engines that rely on Diesel Exhaust Fluid (DEF) to reduce nitrogen oxide (NOx) emissions. When the …
