P0553 Code: Power Steering Pressure Sensor/Switch Circuit High
🟢 Low severity · drivable
Drivable, but the computer may think steering is always under load, causing a high or hunting idle.
What P0553 means
The power steering pressure switch signal is too high, so the computer thinks the power steering is under load even when you drive straight. Because of that, the engine may keep the idle raised or hunt up and down. The cause is usually a stuck switch, a short to voltage, or damaged wiring.
Symptoms
- Check engine light is on
- Idle speed higher than normal
- Idle speed hunting up and down
- Slightly higher fuel use at idle
Common causes
- most common: Stuck power steering pressure switch
- common: Short to voltage in switch wiring
- common: Damaged or corroded connector
- rare: Faulty engine computer
