P0553 — Power Steering Pressure Sensor Circuit Low Input
Drive with caution — fix soon.
What P0553 means
This code means the power steering pressure sensor is sending a signal that's too low, often close to zero volts. It typically points to a wiring short to ground, an open circuit, a bad connector, or a failed sensor. Most repairs involve replacing the sensor or repairing the wiring and connector in its circuit.
Common symptoms
- Check engine light is on
- Engine idles rough or dips when turning
- Engine nearly stalls during parking
- Inconsistent idle at low speeds
- Steering works but idle control is affected
Common causes
- Failed power steering pressure sensor
- Sensor signal wire shorted to ground
- Open circuit in the sensor wiring
- Corroded or disconnected sensor connector
- Damaged wiring harness near the sensor
Typical repair cost
$130 – $350
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0553 code?
Usually yes. The steering still works mechanically, so short-term driving is safe. You may experience rough idle or near-stalling when turning at low speed. Get it checked soon to avoid stalling in traffic or while parking.
How much does it cost to fix a P0553 code?
Most repairs run between $130 and $350. Replacing the sensor is the common fix, while repairing a shorted or broken wire can vary the cost. A diagnosis confirms whether the sensor or its wiring is at fault before any parts are bought.
Is a P0553 code serious?
It's moderate. It won't disable your steering or damage the engine, but the idle and stalling issues can be inconvenient and occasionally unsafe in slow traffic. Repairing it restores stable idle when turning.
What does low input mean on a P0553 code?
Low input means the sensor's voltage signal dropped below its normal range, usually from a short to ground, a broken wire, or a failed sensor. A technician tests the circuit to find whether it's the wiring or the sensor itself before replacing anything.
