September 16, 2020 P0120 Code: Throttle/Pedal Position Sensor “A” CircuitDiagnostic trouble code (DTC) P0120 stands for “Throttle/Pedal Position Sensor ‘A’ Circuit.” It is triggered once the powertrain control module (PCM) detects abnormal voltage readings from one of your car’s TP or APP sensors. To understand the code better, let us briefly discuss how TP and APP sensors operate.
September 15, 2020 P2101 Code: Throttle Actuator “A” Control Motor Circuit Range/PerformanceDiagnostic Trouble Code (DTC) P2101 stands for Throttle Actuator “A” Control Motor Circuit Range/Performance. It is usually triggered when your vehicle’s powertrain control module (PCM) detects that the actual throttle position does not match the desired throttle position. Once this happens, your PCM may put your engine in “limp home September 09, 2020 P0123 Code: Throttle / Pedal Position Sensor “A” Circuit HighIf the engine computer receives a signal from the TP sensor that exceeds the maximum limit for a set period, a P0123 code may get registered by on-board diagnostics.
Code P0123 may be triggered when your car computer receives a signal from the TP sensor that exceeds the maximum limit for August 18, 2020 P2138 Code: Throttle/Pedal Position Sensor/Switch D/E Voltage CorrelationDiagnostic trouble code (DTC) P2138 stands for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation.” It is triggered when the vehicle’s engine control module (ECM) or powertrain control module (PCM) detects that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do not correlate.
Code P1238 indicates that
