P0965

Pressure Control Solenoid B Control Circuit Range/Performance

Q: Is it safe to drive with P0965?

Only briefly. Incorrect line pressure causes slipping and heat that can damage the transmission, so keep trips short until repaired.

Q: Can I just clear P0965?

It returns quickly while the pressure-control fault persists, and clearing it won't restore normal shifting.

Transmission Generic OBD-II Medium

What it means

P0965 means the transmission control module sees pressure control solenoid B responding outside its expected range. This solenoid regulates internal fluid (line) pressure, so a fault leads to harsh or erratic shifting, slipping, and sometimes limp mode. Left unrepaired, incorrect pressure can overheat and damage the transmission.

Medium

Can I keep driving? Short trips only — shifting may be harsh or erratic and the transmission can drop into limp mode; fix promptly to avoid internal damage.

Common symptoms

What you'll notice

Common causes

Damaged, shorted, or corroded wiring or connector at the solenoidCommon
Low or contaminated transmission fluid affecting pressureCommon
Faulty transmission fluid pressure sensorLess often
Failed transmission control module (TCM)Less often

How to diagnose & fix

Work through it in order

Check transmission fluid level and condition first — low or burnt fluid disturbs line pressure.
Read freeze-frame data and inspect the solenoid B connector and wiring for damage or corrosion.
Test the pressure control solenoid B resistance against spec; replace if out of range.
Verify the fluid pressure sensor reads correctly, then replace the solenoid if it is the fault.
If wiring, solenoid, and sensor test good, have the TCM diagnosed. Clear and re-test.
