The P11AA trouble code is a diagnostic trouble code (DTC) that indicates an issue with the cam adjustment actuator in certain vehicles, particularly those equipped with advanced variable valve timing systems. This code typically signifies an implausible signal from the actuator, which can lead to various performance issues in the engine. Understanding this code is crucial for vehicle owners and DIY mechanics, as it can

The P0590 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the cruise control system, specifically the “Cruise Control Multi-Function Input ‘B’ Circuit Stuck.” This code is part of the OBD-II system, which monitors various vehicle components to ensure optimal performance. When the Powertrain Control Module (PCM) detects that the multi-function input circuit associated with the cruise control is stuck or

The P1695 trouble code is a diagnostic trouble code (DTC) that indicates a communication issue within a vehicle’s electronic systems. Specifically, it is often associated with a malfunction in the fuel composition sensor circuit or a loss of communication between the body control module (BCM) and the engine control module (ECM). This code can affect various vehicle functions, leading to performance issues or even preventing

The P166A trouble code is an OBD-II diagnostic code that indicates a problem related to the fuel temperature sensor circuit, specifically “Fuel Temperature Sensor B Circuit Range/Performance.” This code is part of a broader category of powertrain trouble codes and can affect various vehicle systems, leading to performance issues. Understanding this code is essential for vehicle owners and DIY mechanics who want to diagnose and

The P06C5 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the glow plug for cylinder 1 in diesel engines. Specifically, it means that the powertrain control module (PCM) has detected an incorrect level of resistance in the glow plug circuit for that cylinder. This code is particularly relevant for OBD-II vehicles, which include a wide range of makes and models,

The P1547 trouble code is a diagnostic trouble code (DTC) that indicates a specific issue within the vehicle’s powertrain control system. This code can be triggered by various factors depending on the vehicle make and model, but it generally points to problems related to the oxygen sensor heater circuit or, in some cases, issues with the air conditioning system performance. Understanding this code is essential

The P1199 trouble code is an OBD-II diagnostic code that indicates an issue with the fuel rail/system pressure, specifically noting that the pressure is too high. This code can arise in various vehicle makes and models, often leading to performance issues and triggering the check engine light. Understanding the causes, symptoms, and solutions for this trouble code is essential for vehicle owners and DIY mechanics

The P2344 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the knock sensor in cylinder #9 of the engine. When the powertrain control module (PCM) detects that the signal from the knock sensor is above an acceptable threshold, it triggers this code. This can lead to various engine performance issues, including knocking sounds, reduced efficiency, and potential engine damage if

The P1332 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the engine’s knock sensor, specifically “Knock Sensor 4 Low Input.” This code is crucial for maintaining optimal engine performance, as the knock sensor plays a vital role in detecting engine knocking or pinging, which can lead to severe engine damage if not addressed. When the Engine Control Module (ECM) detects

The P2506 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Control Module (ECM) or Powertrain Control Module (PCM) regarding the power input signal. Specifically, it signifies that the power input signal is either too low or too high, which can lead to various performance problems in the vehicle. Understanding this code is crucial for vehicle owners and DIY
