P2736
Pressure Control Solenoid F Control Circuit/Open
Transmission
Generic OBD-II
Medium
What it means
P2736 means the transmission control module detected an open in the control circuit for pressure control solenoid "F," a valve that regulates shift hydraulic pressure. With the circuit open the solenoid can't be commanded, so the transmission often shifts harshly or drops into limp mode. It's typically a wiring, connector, or solenoid fault, not an engine problem.
Medium
Can I keep driving? May shift harshly or drop into limp mode with the circuit open — the engine starts and runs fine, but drive gently to a shop.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh or slipping shifts
- Transmission stuck in limp/failsafe mode
- Reduced fuel economy
Common causes
Most likely first
- Open in the pressure control solenoid F control circuitLikely
- Disconnected, corroded, or damaged solenoid connectorCommon
- Faulty pressure control solenoid FCommon
- Internal transmission harness faultLess often
- Faulty TCM/PCM driver (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame; confirm an open on the pressure control solenoid F control circuit.
- Inspect the solenoid connector and wiring for opens or corrosion.
- Measure solenoid resistance and check continuity back to the module.
- Inspect the internal transmission harness.
- Replace the solenoid or repair the circuit; clear and retest.
FAQ
Quick answers
Is it safe to drive with P2736?+
The engine runs fine, but with the solenoid circuit open the transmission can't control that pressure, so it may shift harshly or enter limp mode. Drive gently to a shop and skip towing until repaired.
Can I just clear P2736?+
An open circuit won't reset itself — the code returns immediately until the wiring, connector, or solenoid is repaired.
