P0552 Power Steering Pressure Sensor Circuit Low Input
PS pressure sensor signal voltage below threshold — open, short to ground, or sensor failure. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive with P0552?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
