Where is the transmission fluid pressure sensor located?
The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.
What is a P0843 code?
P0843 is an OBD-II generic code for a voltage problem with the transmission fluid pressure sensor in that the signal being sent to the engine control unit is higher than the manufacturer’s parameters for the desired amount of fluid pressure for that given driving condition.

What is code P0776 mean?
pressure control solenoid circuit
Code P0776 is an indication that your vehicle’s PCM has found an abnormality related to the electronic pressure control solenoid circuit or simply the solenoid itself.
What does a transmission fluid pressure sensor do?
The transmission oil pressure sensor’s primary function is to relay information to the ECM that regulates control of the transmission. However, if the switch is damaged or not sending information correctly to the ECM, the transmission may default into “limp” mode.
What is pressure control solenoid?
Transmission Pressure Control Solenoid: DESCRIPTION The transmission pressure control solenoid controls the fluid pressure to the internal friction plate clutches or drum bands. A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating.
