Causes and Fixes P0841 Code: Transmission Fluid Pressure Sensor / Switch A Circuit Range Performance

How to fix P0841 Code: Transmission Fluid Pressure Sensor / Switch “A” Circuit Range Performance A P0841 code is set when the computer (ECM/PCM) receives a signal from the transmission fluid pressure sensor (TFPS) is out of range. It can also be set if the voltage on the TFPS circuit is not correct. Possible Causes of a P0841 Code: Low or Overfilled Transmission Fluid Dirty Transmission Fluid and Filter Bad Transmission Fluid Pressure Sensor/Switch Bad Transmission Fluid Pressure Sensor/Switch Wiring Bad Computer (TCM/PCM) By using this information, the user assumes all risks of use.
