The P1701 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction within the transmission control module (TCM) or its associated circuitry. This code is particularly relevant for vehicles equipped with automatic transmissions, as it signifies that the TCM is not receiving the correct signals necessary for optimal operation. Understanding this code is crucial for vehicle owners and DIY mechanics, as ignoring it
The P1126 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the throttle control system in a vehicle, particularly related to the throttle control motor relay. When this code is triggered, it generally means that the Engine Control Module (ECM) has detected an open circuit in the throttle control motor relay, which can lead to various performance issues, including limited engine
The P2291 trouble code is a diagnostic trouble code (DTC) indicating “Injector Control Pressure Too Low – Engine Cranking.” This code is primarily associated with diesel engines but can also appear in gasoline direct injection systems. When the powertrain control module (PCM) detects that the injector control pressure is below the manufacturer’s specified threshold during engine cranking, it triggers this code. Understanding the causes, symptoms,
The P0119 trouble code refers to an issue with the Engine Coolant Temperature (ECT) Sensor Circuit, specifically indicating that the sensor is providing an intermittent or erratic signal to the Engine Control Module (ECM). This code is part of the On-Board Diagnostics II (OBD-II) system and can affect various vehicle makes and models manufactured after 1996. Understanding this code is crucial for vehicle owners and
The P1280 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Injection Control Pressure (ICP) sensor in certain diesel engines, particularly those in Ford vehicles. This code signifies that the ICP sensor is reporting a pressure reading that is lower than expected, which can lead to performance issues in the engine. Understanding this code is essential for vehicle owners and
The P1515 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the electronic throttle control system. Specifically, it signifies a discrepancy between the commanded throttle position and the actual throttle position as detected by the vehicle’s Powertrain Control Module (PCM). When this code is triggered, the PCM may activate the check engine light and can lead to reduced engine power mode,
The P043E trouble code is a diagnostic code that indicates an issue with the Evaporative Emission System (EVAP) in a vehicle. Specifically, it signifies a low flow condition detected in the leak detection reference orifice of the EVAP system. This orifice is crucial for measuring pressure and flow within the system, and when it becomes clogged or damaged, it can lead to increased emissions and
The P0104 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Mass Air Flow (MAF) sensor circuit. Specifically, it signifies that the MAF sensor is providing an intermittent or erratic signal to the Engine Control Module (ECM). This can lead to various performance issues in the vehicle, including poor fuel economy, rough idling, and potential engine damage if not addressed
The P0777 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the automatic transmission system, specifically relating to the Pressure Control Solenoid B. This solenoid plays a crucial role in regulating hydraulic pressure within the transmission, which is essential for proper gear shifting and overall vehicle performance. When the Powertrain Control Module (PCM) detects that the Pressure Control Solenoid B is
The P1445 trouble code is a diagnostic trouble code (DTC) that indicates a “Purge Flow Sensor Circuit High Input.” This code is primarily associated with the vehicle’s evaporative emissions control (EVAP) system, which is responsible for preventing fuel vapors from escaping into the atmosphere. When the Powertrain Control Module (PCM) detects a voltage from the purge flow sensor that exceeds the expected range, it triggers
