The P084E: Transmission Fluid Pressure Sensor/Switch ‘H’ Circuit Intermittent refers to an issue where the transmission fluid pressure sensor/switch ‘H’ circuit experiences intermittent signal problems. This can be caused by faulty wiring, connector issues, or a malfunctioning transmission fluid pressure sensor or transmission control module (TCM). Consistent transmission fluid pressure readings are essential for optimal transmission performance.
P084E – Quick Overview

| Is it serious? | Yes, intermittent faults can cause unpredictable transmission performance or shifting issues. |
| Possible causes | – Intermittent issues with the transmission fluid pressure sensor/switch ‘H’ – Wiring or connector issues – Faulty transmission control module (TCM) |
| How to diagnose? | – Test for intermittent faults in the circuit – Inspect wiring and connectors – Replace faulty components if needed |
P084E Meaning
The P084E: Transmission Fluid Pressure Sensor/Switch ‘H’ Circuit Intermittent code indicates that the circuit related to the transmission fluid pressure sensor/switch ‘H’ is experiencing inconsistent signals. This can cause improper transmission function, leading to shifting difficulties or erratic transmission performance.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any additional codes related to the transmission system or fluid pressure circuit. | OBD-II Scanner |
| Inspect Transmission Fluid Pressure Sensor | Visually inspect the transmission fluid pressure sensor/switch ‘H’ for signs of damage, wear, or corrosion that may be causing intermittent issues. | Flashlight, Safety Gloves |
| Test for Intermittent Faults | Use diagnostic tools to test for intermittent signal issues from the transmission fluid pressure sensor/switch ‘H’. | Multimeter, Diagnostic Tool |
| Check Wiring and Connectors | Inspect the wiring and connectors for signs of loose connections, damage, or corrosion that could result in intermittent signal faults. | Flashlight, Multimeter |
| Replace Faulty Components | If the sensor, wiring, or connectors are found to be faulty, replace the necessary components to ensure consistent signal operation. | Replacement Parts, Basic Tools |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and test drive the vehicle to ensure proper transmission operation. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the system to confirm that the P084E code does not return. | OBD-II Scanner |
