Technical Specifications

Installation Guide

The Bosch 0261222019 is engineered for straightforward installation, allowing technicians to replace the existing fuel tank pressure sensor without extensive modifications.

1. Safety First: Disconnect the vehicle’s battery and ensure the engine is cool before proceeding.
2. Accessing the Sensor: Locate the fuel tank pressure sensor near the top of the fuel tank. In most Volvo models, it is mounted on a bracket that can be removed with standard socket tools.
3. Disconnecting the Old Unit: Carefully detach the electrical connector and unscrew the mounting bolts. Note the orientation of the sensor for correct reinstallation.
4. Installing the New Sensor: Place the Bosch 0261222019 onto the bracket, aligning it with the mounting holes. Secure it with the original bolts, ensuring a tight fit to prevent leaks.
5. Reconnecting Electronics: Plug the sensor’s connector into the vehicle’s ECU harness. Verify that the connection is firm and free of debris.
6. Testing: Reconnect the battery, start the engine, and use an OBD scanner to confirm that the sensor reports valid pressure values and passes its self‑diagnostic check.
