The P1694 trouble code is a generic diagnostic trouble code (DTC) that indicates a communication issue within the vehicle’s onboard computer systems. Specifically, it signifies that the Powertrain Control Module (PCM) is not receiving expected messages from the Engine Control Module (ECM) or that there is a failure in the Controller Area Network (CAN) bus communication. This can lead to various symptoms affecting vehicle performance,

The P228C trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel pressure regulator in a vehicle. Specifically, it means “Fuel Pressure Regulator 1 Exceeded Control Limits – Pressure Too Low.” This code is primarily applicable to diesel-powered vehicles but can also affect various gasoline engines. When the powertrain control module (PCM) detects that the fuel pressure regulator’s control circuit

The P0369 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the camshaft position sensor “B” circuit on bank 1 of an engine. This code is part of the OBD-II system, which monitors various engine parameters to ensure optimal performance and emissions control. When the Powertrain Control Module (PCM) detects an intermittent signal from the camshaft position sensor, it triggers the

The P2431 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Secondary Air Injection System (SAIS) in a vehicle. Specifically, it refers to the “Secondary Air Injection System Airflow/Pressure Sensor Circuit Range/Performance Bank 1.” This code is triggered when the Powertrain Control Module (PCM) detects that the voltage signal from the air pressure sensor is outside the normal range, indicating

The P1296 trouble code is a diagnostic trouble code (DTC) that indicates an Engine Cooling System Malfunction. This code is typically triggered when the Engine Control Module (ECM) detects an issue with the engine’s coolant temperature sensor or the cooling system itself. Understanding this code is crucial for vehicle owners and DIY mechanics, as it can lead to severe engine damage if not addressed promptly.

The P0757 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the transmission control system, specifically related to the shift solenoid “B.” This code is commonly logged by the vehicle’s powertrain control module (PCM) when it detects that the shift solenoid is stuck in the “on” position. This issue can lead to various transmission problems, including difficulty in shifting gears, reduced

The P3190 trouble code is a diagnostic trouble code (DTC) that indicates “Poor Engine Power.” This code is particularly relevant for hybrid vehicles, such as the Toyota Prius, where it can lead to significant performance issues. When the vehicle’s engine control module (ECM) detects that the engine’s output power is below acceptable levels, it triggers this code. This situation can arise from various underlying issues,

The P0075 trouble code indicates an issue with the Intake Valve Control Circuit (Bank 1). This code is part of the On-Board Diagnostics II (OBD-II) system and is triggered when the Powertrain Control Module (PCM) detects a fault in the circuit that controls the intake valve timing solenoid. The solenoid plays a crucial role in managing the engine’s performance by regulating the timing of the

The P0297 trouble code is a diagnostic code that indicates a “Vehicle Overspeed Condition.” This code is generated when the powertrain control module (PCM) detects that the vehicle has exceeded its maximum allowable speed, typically set at 100 mph for most vehicles. When this condition occurs, the PCM will disable fuel injection to all cylinders, resulting in a significant loss of power and speed. Understanding

The P2723 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Pressure Control Solenoid “E” in a vehicle’s transmission system. Specifically, it signifies that the solenoid is either malfunctioning or stuck in the “off” position, which can lead to significant transmission issues if not addressed promptly. The Powertrain Control Module (PCM) monitors the performance of the solenoid and triggers this
