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.
Frequently Asked Questions
What does the Walker 256-1277 oil pressure switch do?
It monitors engine lubrication pressure and activates the dashboard warning light or feeds a signal to the ECU when oil pressure falls below safe operating thresholds.
Which vehicles does this switch fit?
It's a direct-fit replacement for the 1995 Nissan Pathfinder and 2007-2008 Suzuki XL-7. Check the Buyer's Guide tab for engine-level applications for your vehicle.
What are signs my oil pressure switch may need replacing?
Common signs include an oil light that flickers, false warnings, or no signal under actual low-pressure conditions. Diagnose the cause before replacing, as other faults can mimic these symptoms.
Where does the switch install?
It threads directly into the factory location—typically the engine block or oil filter housing—and connects to the existing wiring with no modifications.
Is this an OE replacement part?
Yes. It's an OE Replacement component calibrated to match original specifications for pressure activation point, thread pitch, and electrical response.
