P0552 Code: Power Steering Pressure Sensor/Switch Circuit Low
🟢 Low severity · drivable
Drivable, but the engine may not raise its idle when steering, causing stumbles at low speed.
What P0552 means
The power steering pressure switch signal is too low, which the computer reads as "no steering load" even when you turn the wheel. Normally the switch sends a signal when steering pressure rises. A low reading means the engine will not get the idle boost it needs, so it can stumble or stall during parking maneuvers.
Symptoms
- Check engine light is on
- Engine idle drops when turning the wheel
- Stalling at low speed or when parking
- Steering may feel heavier
Common causes
- most common: Faulty power steering pressure switch
- common: Open or shorted switch wiring
- common: Loose or corroded connector
- less common: Low power steering fluid
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Inspect and clean the switch connector | Yes | $0–50 |
| Replace the power steering pressure switch | Yes | $40–150 |
| Repair switch wiring or check the fluid level | Mechanic | $50–200 |
Frequently asked questions
Can I drive with a P0552 code?
Yes, but watch for engine stumbles when steering at low speed. Avoid sudden parking maneuvers until it is fixed.
What does a low steering pressure signal mean?
The switch is not sending a load signal, so the computer never raises the idle even when you are turning the wheel.
How much does it cost to fix a P0552?
Cleaning a connector is nearly free. Replacing the switch costs $40–$150, and wiring repairs run $50–$200.
