P0867 Code: Transmission Fluid Pressure

The P0867 code means the transmission fluid pressure is not what the computer expects. Check the fluid level and condition before anything else. The cause can range from a dirty filter to a worn pump.

What the P0867 code means

The computer compares the pressure measured by the sensor with the pressure it expects for the current gear and load. If they do not match, it stores the P0867 code, and P0868 or P0869 if the pressure is low or high.

On any transmission code, the first check is the fluid: the correct level using the manufacturer procedure (often with the engine running and the fluid at a specific temperature), a red or pink color and no burnt smell. Low or degraded fluid causes slipping, harsh shifts and solenoid or gear ratio codes that disappear once it is corrected.

The P0700 guide explains how transmission codes are read and why you need a scan tool that can reach the transmission module.

P0867 code symptoms

  • Harsh shifts or slipping.
  • Limp mode.

Likely causes of the P0867 code

  1. Wrong fluid level. Too low causes slipping, and too high causes foaming.
  2. Clogged transmission filter, which reduces the flow the pump can draw.
  3. Worn oil pump, which delivers less pressure when hot.
  4. Pressure solenoid that does not regulate correctly.
  5. Pressure sensor that gives a wrong reading.

How to diagnose the P0867 code step by step

  1. Check the fluid.
  2. Measure the pressure with a gauge.
  3. Compare it with the sensor reading.

How to fix the P0867 code

  • Correct the level, or change the fluid and filter.
  • Replace the solenoid or the sensor.
  • Repair the pump if necessary.

Technical reference data

  • Line pressure: check the transmission service manual.
  • Reference values are only a guide, so look up the manufacturer data for your vehicle.

Brand-specific notes

A P0867 code is a general pressure code, so it does not point at one part. Fluid and filter come first, and a gauge reading separates a real pressure problem from a bad sensor.

P0867 on Nissan

This code is frequent on CVT transmissions, such as the Nissan Jatco units.

P0867 on GM

This code is frequent on the GM 6T transmission.

Frequently asked questions about P0867

Can I drive with a P0867 code?
With caution. If the transmission slips or shifts harshly, stop driving it and have it checked, because low pressure can damage the clutches quickly.
Can the fluid be the cause?
Yes. A wrong level or degraded fluid is the first thing to check.
What usually fails?
The fluid level, the filter or the solenoid.
How much does it cost to fix P0867?
Between $100 and $2,500, from a fluid and filter service up to internal repairs.
What does the P0867 code mean?
It is a generic OBD2 code that means the transmission fluid pressure does not match what the computer expects.
