The P2109 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the throttle/pedal position sensor “A” minimum stop performance. This code is part of the On-Board Diagnostics II (OBD-II) system and is applicable to a wide range of vehicles equipped with electronic throttle control systems. When the powertrain control module (PCM) detects that the throttle position sensor (TPS) is not functioning
The P1423 trouble code is a diagnostic trouble code (DTC) that indicates a communication issue with the accessory power module (APM) in certain vehicle models, particularly Toyota. This code typically arises when the vehicle’s onboard computer detects that the APM is not receiving the necessary signals or voltage to operate correctly. Understanding and resolving this code is crucial for maintaining vehicle performance and ensuring compliance
The P1490 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the vacuum cut valve bypass valve circuit, primarily associated with the Evaporative Emission Control (EVAP) system. This code is often triggered when the Engine Control Module (ECM) detects an improper voltage signal from the vacuum cut valve. While it may not immediately affect drivability, it can lead to increased emissions
The P1212 trouble code is a diagnostic trouble code (DTC) that indicates issues related to the Injection Control Pressure (ICP) in diesel engines, particularly in Ford vehicles. This code signifies that the engine control module (ECM) has detected that the ICP is not at the expected level during engine operation. The P1212 code can lead to various symptoms, including rough engine performance, difficulty starting, or
The P2105 trouble code is a diagnostic trouble code (DTC) that signifies a problem with the Throttle Actuator Control System, specifically indicating a “Forced Engine Shutdown.” This code is part of the OBD-II system and is applicable to various vehicles equipped with electronic throttle control (ETC) systems. When the powertrain control module (PCM) detects a malfunction within this system, it triggers the P2105 code, often
The P1249 trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the wastegate control system in vehicles, particularly those equipped with turbocharged engines. This code is often associated with an overboost condition, where the engine’s turbocharger is producing more boost pressure than the engine can handle. The Powertrain Control Module (PCM) detects this condition and sets the P1249 code, which
The P0528 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the fan speed sensor circuit, specifically signifying “Fan Speed Sensor Circuit No Signal.” This code is triggered when the Powertrain Control Module (PCM) detects that it cannot receive a signal from the fan speed sensor, which is crucial for regulating the cooling fan’s operation. If left unaddressed, this issue can
The P1136 trouble code is an OBD-II diagnostic code that indicates a problem with the fuel system, specifically relating to the long-term fuel trim on bank 1 of the engine. This code typically signifies that the engine control module (ECM) has detected a lean condition, meaning that there is insufficient fuel being delivered to the engine compared to the amount of air entering it. Such
The P2088 trouble code is an OBD-II diagnostic code indicating an issue with the camshaft position actuator control circuit on bank 1 of the engine. Specifically, it signifies that the ‘A’ camshaft position actuator is experiencing a low voltage condition. This code can trigger a variety of symptoms affecting engine performance, fuel efficiency, and overall drivability. Understanding this code is crucial for vehicle owners and
The P0114 trouble code indicates an issue with the Intake Air Temperature (IAT) sensor circuit, specifically that the signal from the sensor is intermittent or erratic. This code is applicable to many vehicles manufactured since 1996. The IAT sensor plays a crucial role in engine performance by measuring the temperature of the incoming air, which helps the Engine Control Module (ECM) adjust fuel delivery and
