P0843 Code: Transmission Fluid Pressure Sensor / Switch “A” Circuit HighNote: The definition of the P0843 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
Your PCM/TCM triggers the P0843 code if it receives a voltage signal from the TFPS that doesn’t match the normal operating voltage.
What are the
P0842 Code: Transmission Fluid Pressure Sensor / Switch “A” Circuit LowDon’t hesitate to troubleshoot a P0842 code because it can cause serious damage to your vehicle in the long run.
P0876 Code: Transmission Fluid Pressure Sensor/Switch D Circuit Range PerformanceThe TFPS converts transmission pressure into electrical signals for the TCM or the powertrain control module (PCM). The PCM uses the voltage signal when a shift occurs or to determine the right amount of transmission operating pressure.
P0989 Code: Transmission Fluid Pressure Sensor/Switch “E” Circuit LowThe sensor turns the mechanical pressure applied by the transmission fluid into a voltage signal. It transmits the signal to the TCM or PCM, which shares the readings with other controllers when the need comes up.
P0523 Code: Engine Oil Pressure Sensor/Switch “A” Circuit HighThe PCM monitors engine oil pressure with the help of the Engine Oil Pressure sensor. The P0523 code is typically logged when the PCM receives high readings from this sensor. This code belongs to a range of diagnostic trouble codes that refer to oil pressure problems. Related DTCs include P0520,
P0868 Code: Transmission Fluid Pressure Sensor LowFluid pressures vary from platform to platform. For example, this table provides the proper fluid pressures (measured at the external test port) on a 2017 Ford F150.
