Installation Guidelines

1. Disconnect the battery: Ensure safety before working on electrical components.
2. Remove the old sensor: Use appropriate tools to unscrew or detach the existing pressure sensor from the fuel rail.
3. Prepare the new sensor: Verify that the sensor’s mounting interface matches the vehicle’s specification. Apply a thin layer of anti‑seize compound if recommended.
4. Install the sensor: Secure it in place, tightening to manufacturer torque specifications.
5. Reconnect wiring: Attach the power, ground, and signal leads to the ECU connector or dedicated harness.
6. Re‑connect the battery and test: Power up the system and verify that the ECU registers a valid pressure reading. Check for any error codes related to fuel pressure.
