P0867 Code: Meaning, Symptoms, Causes & Fix

Overview

When P0867 appears, the control module has detected abnormal behavior related to Transmission Fluid Pressure in transmission and shift management.

Symptoms

harsh or delayed shifting
reduced acceleration
gear hunting

Common causes

Component failure in the monitored system affecting transmission fluid pressure
Control module logic or calibration issue
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0867

Confirm P0867 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to transmission fluid pressure for obvious defects.
Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0867

Low: This code is low to moderate severity in most cases, but diagnosis is still recommended to avoid recurring warnings.

Can you drive with P0867?

The vehicle is often drivable with P0867, but plan a repair window to prevent repeat faults.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (generic) in the transmission fluid pressure circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0867 remains cleared under the conditions that originally set the code.

Fix options

Inspect circuit and connector condition.
Test component operation and replace if faulty.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$180-$650

Common mistakes when diagnosing P0867

Replacing parts without verifying voltage, ground, and signal integrity first.
Ignoring related stored/pending codes that indicate upstream faults.
Skipping post-repair verification drive cycle and readiness checks.

P0867 in common vehicles

P0867 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0867?

P0867 is commonly set by generic faults affecting transmission fluid pressure.

How much does it cost to fix P0867?

For P0867, repair costs are typically $180-$650 depending on exact root cause, labor rates, and part quality.

Can I clear P0867 without repair?

You can clear P0867 temporarily, but the code usually returns until the underlying fault is corrected.
