P2733
Pressure Control Solenoid F Stuck On
Automatic transmission
Generic OBD-II
Medium
What it means
P2733 means pressure control solenoid 'F' appears stuck in the on position, staying energized or applied when it should release. Because it can't modulate hydraulic pressure, shifts become harsh or firm, the transmission may bind or slip, and it can enter limp mode. Common causes are a stuck or failed solenoid, valve-body debris, or dirty fluid. It affects the transmission, not engine starting.

Can I keep driving? Driveable but expect harsh or firm shifts, binding, or limp mode — fix it promptly to avoid transmission damage.

How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition.
- Scan and compare the solenoid command with actual pressure/gear data.
- Inspect the solenoid wiring and connector for a short.
- Check the solenoid for mechanical sticking and measure its resistance.
- Clean or replace the valve body/solenoid as needed, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2733?+
Short trips are usually possible, but a stuck-on solenoid causes harsh, binding shifts that can damage the transmission. Have it repaired soon.
Can I just clear P2733?+
It returns once the solenoid again stays applied. Fix the sticking solenoid, valve body, or fluid first, then clear and re-test.
