Where is the Transmission Pressure Sensor Located

The transmission pressure sensor is located in the transmission of a vehicle. It is typically found near the valve body, which controls oil flow through the transmission. The pressure sensor measures the amount of hydraulic pressure present within the system and sends this information to the engine control unit (ECU).

This data helps ensure that gear shifts are smooth and efficient, as well as helping protect against damage from overloading or excessive strain on components. In addition, it can be used to monitor temperature changes in order to detect potential problems before they become serious issues.

The transmission pressure sensor is typically located in the transmission itself and is used to monitor the hydraulic pressure inside. It may be mounted directly on a valve body or placed elsewhere depending on the make and model of your vehicle. This sensor assists with proper gear shifting, as it communicates data to the engine control unit which then uses that information to adjust the shifting points accordingly.

How Much Does It Cost to Replace a Transmission Fluid Pressure Sensor?

Replacing a transmission fluid pressure sensor can be an expensive undertaking. Depending on the make and model of your vehicle, it could cost anywhere from $100 to over $1000 for parts and labor. The exact price will depend on the type of car you have and how difficult it is to access the part that needs replacing.

Additionally, if you choose to do the job yourself, then you’ll need to factor in any special tools or other supplies that may be required for installation. If you take your vehicle into a repair shop, they’ll likely charge an additional fee for diagnostic tests as well as labor costs related to removing and reinstalling components during the repair process. All in all, replacing a transmission fluid pressure sensor can be quite costly; so before starting any repairs or replacements always consult with an experienced mechanic who can provide accurate estimates based on your specific situation.

What Happens When a Transmission Fluid Pressure Sensor Goes Bad?

When a transmission fluid pressure sensor goes bad, it can cause some major problem in the transmission system of a car. The most common symptom is that the vehicle will not shift gears properly and may even slip out of gear while driving. This can happen as the sensor starts to malfunction and stops providing an accurate reading of the amount of hydraulic pressure in the transmission line.

Without this data, it becomes impossible for your car’s computer to accurately determine when to shift between gears. In addition, if there is too much or too little pressure present in certain parts of your automatic transmission, leaks are more likely to occur which can damage components within your vehicle’s drivetrain such as seals, solenoids and clutches. If left unchecked then these problems could lead to reduced performance from your car and expensive repairs down the road.

What is Transmission Pressure Switch?

A transmission pressure switch is a safety device that automatically shuts off the power to your vehicle’s transmission if it fails to sense fluid pressure. This ensures that your car doesn’t suffer from any major damage due to a lack of lubrication or cooling. The switch uses electrical contacts to detect when the oil pressure in the transmission drops below a certain level, at which point it will cut off all power and prevent further damage from occurring.

It’s important for drivers to be aware of their vehicle’s transmission system and how this particular component works as part of their regular maintenance routine, as failure can lead not only to expensive repairs but potentially dangerous consequences too.

What Causes a Transmission Pressure Sensor to Go Bad?

A transmission pressure sensor plays a critical role in the operation of an Automatic Transmission Vehicle (ATV). It is responsible for monitoring and adjusting the transmission fluid pressure which helps ensure smooth shifting. Unfortunately, there are several factors that can cause this vital component to fail or go bad.

The most common causes include: wear and tear due to age and usage, mechanical damage or failure due to lack of maintenance, poor electrical connections/wiring leading to faulty readings, contamination of the transmission fluid by dirt or debris resulting in inaccurate measurements, and issues with the sensor itself such as incorrect calibration. If any of these problems occur it is important to take your vehicle into a certified mechanic right away for proper diagnosis and repair. Failing to do so could result in further damage not only to your vehicle but also more expensive repairs down the road if left unchecked.

P0841 Transmission Fluid Pressure Sensor/Switch a Circuit Location

The P0841 transmission fluid pressure sensor/switch is located in the circuit of the vehicle’s transmission. It monitors the internal pressure of the system and sends a signal to the engine control unit when abnormal levels are detected, allowing it to make necessary adjustments. The switch typically consists of a metal housing with an electrical connector that connects it to other components in order to send information back and forth.

P0847 Transmission Fluid Pressure Sensor/Switch B Circuit Location

The P0847 Transmission Fluid Pressure Sensor/Switch B Circuit is located in the transmission and is used to monitor the pressure of the fluid within it. It sends an electrical signal to the Powertrain Control Module (PCM) when there is a change in pressure, allowing for adjustments to be made as needed. The sensor can also be used as an engine diagnostic tool by providing information about shifting points and other transmission-related issues.

How to Test Transmission Pressure Switch

Testing the transmission pressure switch is an important part of maintaining a properly functioning vehicle. To do this, you’ll need to locate the pressure switch and then use a multimeter to measure the voltage at its terminals. If voltage readings are not consistent with what’s specified in your vehicle’s service manual, it may be time to replace or repair your transmission pressure switch.


In conclusion, the transmission pressure sensor is a critical component in monitoring and controlling the transmission system of your vehicle. It is typically located on or near the transmission pan and can be easily accessed for testing or replacement when needed. Knowing where to find it can help you diagnose any issues with your car’s transmission and make sure that everything continues to run smoothly.
