P0552: Power Steering Pressure Sensor Circuit Low Input
HighPowertrainIdle Control
What does P0552 mean?
P0552 is a diagnostic trouble code indicating "Power Steering Pressure Sensor Circuit Low Input". The ECU is detecting a voltage reading that is below the expected range in the idle control circuit. This typically points to a wiring short, a faulty sensor, or a grounding issue.
Symptoms you may notice
- Check engine light (MIL) illuminated on dashboard
- Intermittent warning lights
- Erratic gauge readings
Estimated repair cost
Typical range in Australia (parts + labour)
$100 – $500 AUD
Common causes
- Damaged or corroded wiring harness
- Loose or disconnected electrical connector
- Failed idle control sensor or actuator
- Blown fuse in the related circuit
- Poor ground connection
What should you do?
This code sits in the steering system. Power assistance can cut out without warning, which makes the wheel go heavy, usually worst at parking and low speeds. Steering itself does not disappear, but the effort changes suddenly. Get it diagnosed before driving.
