Error Code P084E: What It Means & What To Do?

<<See All OBD Codes

The trouble code P084E can be defined as Transmission Fluid Pressure Sensor/Switch "H" Circuit Intermittent. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

We learn more by looking for the answer to a question. That’s the reason why we are here to provide you the answers for all your questions. The transmission fluid pressure sensor/switch is generally situated on the side of the valve body inside the transmission, but there can be sometimes where it may be found screwed into the side of the transmission case/body itself. The mechanical transmission pressures are converted by the TFPS into an electrical signal for the powertrain control module or transmission control module.

What causes this problem with the Transmission Fluid Pressure Sensor/Switch "H" Circuit Intermittent?

• There can be an intermittent open in the signal circuit to the TFPS sensor
• There can be inoperative TFPS sensor
• There can be distorted PCM
• Voltage in the signal circuit to the TFPS sensor might have an intermittent short
• Some issues related to the intermittent short to ground in the signal circuit to the TFPS sensor

1. Body Control Module Component - The P084E code can also arise due to some issues in Body Control Module Component. So, it is advised to replace them as soon as possible.
2. Auto Transmission Shift Solenoid - Do you remember when was the last time you got your car Auto Transmission Shift Solenoid checked up? A damaged Auto Transmission Shift Solenoid can cause a lot of issues like displaying P084E code.
3. Electronic Control Unit - Electronic Control Unit is an important car part which should never be neglected. May be there is some fault in it due to which P084E code may start flashing.
4. Engine Control Module - Is your Engine Control Module damaged or broken? Don’t worry as we have solutions for all your problems.
5. Powertrain Control Module - Defective car Powertrain Control Module can be a major reason why P084E code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
6. Auto Transmission Control Module - Everything is okay with the Electronic Control Unit and still OBD code P084E triggering? Then there must be some defects in Auto Transmission Control Module. Replace them as soon as possible

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

You must always start with a technical service bulletin search for your particular vehicle. Your issue may be a familiar issue with a well-known fix put out by the manufacturer and can help a lot in save your precious time as well as money during the process of diagnosis.

A great example of this would be if there are any known power related codes set along with the P084E, or if there is more than one pressure sensor/switch code set. If this is the situation, then you should start your diagnosis with the power related fault code first, or with the multiple code diagnosis first, as this may be the reason why P084E code is appearing.

After that the Transmission Fluid Pressure Sensor/Switch should be located on your specific vehicle. The TFPS is generally present 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. Now once you have located it, the connector and wiring should be visually inspected.

Carefully search for scraping, rubbing, bare wires, burn spots or melted plastic. The connector should be pulled apart and carefully inspect the terminals inside the connector. You must check if they look burned or have a green tint which would indicate corrosion, especially if they are attached outside the transmission case.

Make use of an electrical contact cleaner as well as a plastic bristle brush if cleaning of the terminals is needed. You should allow it to dry and apply electrical grease where the terminals contact. By using a scan tool, the diagnostic trouble codes from memory should be cleared up, and see if P084E code returns. If it does not come into view, then it is an indication that connections are malfunctioning.

Common Mistakes When Diagnosing the P084E Code

• Negligence in the transmission fluid pressure sensor
• Wiring Issue may exist
• Non observance of the transmission control module
• Transmission fluid level is low
