Wacker Neuson 5000156556 Oil Sensor

The Wacker Neuson Oil Sensor is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including VP and WP series single-direction vibratory plate compactors, BPU series reversible vibratory plate compactors, GP series portable generators, PT and PDT series trash and diaphragm pumps, PG series dewatering pumps, CT series concrete trowels, and BFS series floor saws. As a direct genuine OEM part, the meets the exact specifications set by Wacker Neuson for these machines, ensuring consistent performance across the full range of compatible models. This sensor is a critical engine protection component — when it detects low oil pressure or insufficient oil level, it triggers a shutdown to prevent catastrophic engine damage. Stocking a replacement on hand keeps your equipment protected and your crew moving without unscheduled stops.

Key Features

• Genuine OEM Sensing Accuracy — Manufactured to Wacker Neuson's original switching threshold specifications, so the sensor triggers engine shutdown at the correct oil pressure point — not too early, not too late.
• Drop-In Electrical and Thread Compatibility — Matches the original sensor's connector type, thread pitch, and mounting configuration for a straightforward swap with no adaptation needed.
• Broad Cross-Family Fitment — A single part number covers VP and WP vibratory plates, BPU reversible plates, GP generators, PT and PDT pumps, PG dewatering pumps, CT trowels, and BFS floor saws — simplifying parts inventory across your fleet.
• Engine Protection Where It Counts — A functioning oil sensor is the last line of defense against low-oil engine seizure; a failed or bypassed sensor removes that protection entirely, risking total engine loss.
• Safety-Critical Electrical Component — Because this sensor directly governs engine shutdown behavior, using a correctly rated OEM unit ensures the shutdown circuit operates within the machine's designed safety parameters.

The oil sensor monitors engine oil pressure or oil level and sends a signal to the machine's control circuit to shut the engine down if oil conditions drop below a safe operating threshold. This automatic shutdown protects the engine from running dry, which can cause rapid bearing wear, scoring, and irreversible seizure within seconds. When the sensor fails or becomes corroded, it may either allow the engine to run unprotected or trigger false shutdowns — both outcomes interrupt work and risk costly engine damage.
