Product Overview
The sensor is used to report a pressure difference within the machine/engine monitoring system. A failed or drifting sensor can create incorrect pressure warnings or diagnostic behavior even when the underlying mechanical system is operating normally.
Cross-reference data associates this sensor with John Deere 6101 / 10.1L engine-equipped excavator applications and several interchange numbers. Because pressure plumbing and electrical connectors are application-specific, confirm the original number rather than choosing only by excavator family.
Key Features & Performance
- Direct electrical pressure-sensing replacement for listed Deere applications
- Cross-referenced to both 4339559 and AT154530

Frequently Asked Questions
Q: Is this an engine oil-pressure sender?
A: No. This listing is for a differential pressure pickup/sensor used on the specified Deere excavator applications.
Q: Should I replace the sensor without checking hoses/ports?
A: No. Blocked or damaged pressure lines can cause incorrect readings and should be inspected during diagnosis.
Verify sensor number, connector and pressure-port arrangement before ordering.
