A P0552 code on your 2022 Hyundai Santa Fe indicates a low voltage condition in the power steering pressure sensor circuit. This suggests the sensor signal is being pulled to ground.
Low Circuit Analysis
A low voltage reading from the pressure sensor circuit typically indicates a short to ground. The ECM expects a specific voltage range; readings below minimum suggest the signal wire is contacting ground somewhere.
Santa Fe Steering System
The 2022 Santa Fe uses electric power-assisted steering (MDPS) which doesn't have a traditional hydraulic pressure sensor. If P0552 appears, it may relate to a different sensor or be a code interpretation issue.
Electric Power Steering Consideration
Modern Hyundai vehicles with MDPS don't use hydraulic fluid or pressure sensors. The system uses motor current to determine steering effort. Verify your Santa Fe's actual steering configuration before pursuing pressure sensor diagnosis.
Diagnostic Steps
Confirm your Santa Fe has electric power steering—most do. Use Hyundai GDS to verify the actual fault code. If a pressure sensor does exist, check for shorts to ground in the circuit. Test sensor output voltage. Inspect wiring for damage that could cause shorts.
