What does the governor pressure sensor and solenoid do?
What does the governor pressure sensor and solenoid do?
The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older ‘RH’ series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure.
What can cause a pressure control solenoid to default?
Here are this trouble code’s most common causes:
- Defective or faulty pressure control solenoid.
- Dirty transmission filter and/or fluid.
- Faulty transmission pump and/or valve body.
- Clogged hydraulic channels.
- Wiring or connector damage.
- PCM malfunction or damage.
What do pressure control solenoids do?
► What Exactly Does a Pressure control Solenoid do? 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.

What does a transmission fluid pressure sensor do?
The transmission fluid pressure sensor (TFPS) is responsible for converting transmission pressure into electrical signals for the powertrain control module (PCM) or transmission control module (TCM). This voltage signal is used by the PCM or TCM to determine the transmission’s operating pressure.
Where is the transmission pressure solenoid located?
In most cases, solenoids are located inside of the oil pan, connected to the valve body. Depending on what you drive, the technician may be able to replace just the failed shift solenoid.
