The P1289 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Cylinder Head Temperature (CHT) sensor circuit. This code is specific to certain vehicle makes, particularly Ford models, and is triggered when the Powertrain Control Module (PCM) detects that the signal from the CHT sensor is out of range. The
The P2635 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel pump, specifically labeled as “Fuel Pump ‘A’ Low Flow / Performance”. This code is triggered when the Engine Control Module (ECM) detects that the fuel pump is not providing an adequate flow of fuel to the engine, which
The P16CF trouble code is a diagnostic trouble code (DTC) that indicates an issue with the rocker arm oil control solenoid, specifically related to its control circuit. This code is primarily associated with vehicles equipped with variable valve timing (VVT) systems, which enhance engine performance and efficiency by optimizing the timing of the intake and
The P1155 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the air/fuel ratio sensor heater circuit for Bank 2, Sensor 1. This code is primarily associated with vehicles equipped with OBD-II systems, which monitor various components to ensure optimal engine performance and emissions control. When the engine control module (ECM)
The P0160 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit for Bank 2 Sensor 2. This code is triggered when the powertrain control module (PCM) detects that there is no activity from the downstream oxygen sensor, which is typically located after the catalytic converter. The role
The P0752 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the automatic transmission system, specifically relating to the shift solenoid A. When this code is triggered, it signifies that the shift solenoid A is stuck in the “on” position, which can lead to improper gear shifting and various performance issues
The P1120 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the throttle position sensor (TPS). Specifically, it signifies that the actual position of the throttle plate does not match the desired position as determined by the powertrain control module (PCM). This discrepancy can lead to various performance issues, including reduced
The P0748 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Pressure Control Solenoid “A” in a vehicle’s automatic transmission system. This code is part of the OBD-II system, which monitors various components of the vehicle to ensure they are functioning correctly. When the Powertrain Control Module (PCM) detects an
The P20B9 trouble code is a diagnostic trouble code (DTC) that signifies an issue with the Reductant Heater ‘A’ Control Circuit. This code is primarily associated with diesel engines equipped with Selective Catalytic Reduction (SCR) systems, which utilize Diesel Exhaust Fluid (DEF) to reduce harmful emissions. When the Powertrain Control Module (PCM) detects an open
The P1381 trouble code indicates an issue with the cylinder position sensor, specifically an intermittent interruption in its circuit. This sensor plays a crucial role in the engine management system by detecting the position of the number one cylinder, which is essential for sequential fuel injection. When this code is triggered, it can lead to
The P1167 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the heater circuit of the Air/Fuel Ratio (A/F) sensor, specifically for Sensor 1. This sensor plays a crucial role in monitoring the air-fuel mixture in the engine, allowing the engine control module (ECM) to adjust fuel delivery for optimal combustion
