Keep an eye on engine lubrication pressure with the Walker Products Engine Oil Pressure Switch 256-1277 (also written 2561277). It’s a direct-fit replacement for the 1995 Nissan Pathfinder and 2007-2008 Suzuki XL-7 — see the Buyer’s Guide tab for engine-level applications. As an OE Replacement component, it monitors oil pressure and signals the ECU or driver when levels fall below safe operating thresholds.
- Monitors oil pressure levels: Activates the dashboard warning or ECU input when oil pressure drops below safe operating thresholds.
- OE Replacement calibration: Matched to original specifications for pressure activation point, thread pitch, and electrical response.
- Helps protect the engine: Alerts the driver or control system to low-oil-pressure conditions, helping guard against damage from a lack of lubrication.
- Built for harsh conditions: Made with high-temperature, oil-resistant materials to resist heat, oil exposure, and vibration.
Engineered for exact OE fit, it threads directly into the factory location — typically the engine block or oil filter housing — and connects to the existing wiring with no modifications. If a failed oil pressure switch is behind a flickering oil light, false warnings, or no signal under actual low-pressure conditions, this switch replaces it during scheduled service, a drivability repair, or an engine rebuild.
