Do not replace the low-pressure fuel supply sensor.
The operating pressure of the low-pressure fuel supply sensor can found in "DME Diagnostic Query" using the following procedure:
1. Exit the test plan and return to the control unit tree.
2. Select "DME" in the control unit tree.
3. Select " Call Up ECU Functions."
