Where is the transmission pressure sensor located?
Where is the transmission 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 causes low pressure in a transmission?
Insufficient transmission fluid levels due to leaks in the system. Slipping or otherwise malfunctioning transmission. Malfunctioning transmission high pressure pump. Defective transmission temperature sensor.
Can a sensor cause transmission problems?
Intake Air Temperature Sensor The sensor is also a component of the pressure control system for the automatic transmission. If failure of this sensor takes place, then the transmission may produce both soft as well as hard shifting or soft shifting. Drivers may also see transmission fault code.
What does code po846 mean?
The P0846 trouble code indicates that the Powertrain Control Module (PCM) has detected an anomalous fluid reading from the transmission system. If the sensor circuit sends a fluid pressure reading to the PCM that falls outside manufacturer specifications, the P0846 trouble code will be stored.
What causes low pressure in transmission?
What causes low line pressure in a transmission?
Line pressure is normally effected by throttle position and the gear range. Pressure that are lower than specifications are usually caused by leaking seals or a worn oil pump. Higher than normal pressures are usually caused by a faulty pressure regulator.
What are the symptoms of a p0872 engine code?
Symptoms of a P0872 engine code may include: Vehicle starts off in 2nd or 3rd gear (limp in mode) Typically the causes for this code to set are: Short to ground in the signal circuit to the TFPS sensor – possible Failed TFPS Sensor / internally shorted – likely
What does p0872 transmission fluid pressure sensor switch C circuit low?
If all prior tests have passed and you continue to get a P0872, this would most likely indicate a failed TFPS sensor, although a failed PCM/TCM could not be ruled out, nor could internal transmission malfunctions until the TFPS sensor had been replaced. If unsure, seek assistance from a trained automotive diagnostician.
What does p0872 stand for in electrical circuit?
P0872 is typically an electrical circuit (TFPS sensor circuit) issue. This cannot be overlooked in the troubleshooting stage, especially when dealing with an intermittent problem.
