🔵 © ISUMO® More Than a Brand — It’s Quality • Power steering pressure switch with electrical connector designed to monitor hydraulic pressure in the steering system • Sends a signal to the ECU to adjust idle speed during steering load • Direct‑fit replacement for leaking, shorted, or worn pressure switches • Includes OE‑style electrical connector for a secure, stable signal path • Built with high‑pressure‑rated housing and corrosion‑resistant terminals • Restores smooth idle and prevents stalling during low‑speed steering • OE‑style connector for secure, vibration‑resistant fit
🔵 © ISUMO® Functions • Monitors power steering hydraulic pressure • Signals ECU to increase idle speed under steering load • Prevents engine stalling during parking or tight turns • Helps maintain stable RPM and smooth drivability • Supports proper steering assist performance
🔵 © ISUMO® Error Codes • P0550 – Power Steering Pressure Sensor Circuit • P0551 – Power Steering Pressure Sensor Range/Performance • P0552 – Power Steering Pressure Sensor Low Input • P0553 – Power Steering Pressure Sensor High Input • P0554 – Power Steering Pressure Sensor Intermittent
🔵 © ISUMO® Symptoms of Failure • Engine stalling during low‑speed turns • Rough or unstable idle when steering • Check Engine Light on • Hard steering or inconsistent assist • Idle drops when turning the wheel • Fluid leakage from switch body
🔵 © ISUMO® Benefits of Replacement • Restores proper idle compensation during steering • Prevents stalling and rough idle • Improves drivability in parking and tight turns • Ensures accurate pressure feedback to ECU • Long‑term reliability with OE‑grade materials
🔵 © ISUMO® Package Includes • 1 × Power Steering Pressure Switch • 1 × Electrical Connector (if applicable) • OE‑style threaded pressure port
🔵 © ISUMO® Important Notes • Inspect power steering hoses for leaks or damage • Verify fluid level before diagnosing pressure faults • Clear stored codes after installation • Professional installation recommended
