Q: What causes the 4880804 sensor to fail in E320D excavators?
A: Most failures are caused by electrical surges, moisture ingress in the connector, or excessive vibration. If your dashboard shows low pressure alerts despite normal fluid levels, the 4880804 sensor should be inspected immediately.
Q: How to handle fault code 102-3 or 102-4 on my machine?
A: These codes often point to a boost pressure sensor circuit fault. First, check the wiring harness. If the wiring is intact, replacing the 488-0804 sensor is the most effective solution to clear the code and restore turbo efficiency.
