Walker Products 256-1021 oil pressure switch for the 2008-2025 Honda Accord and other vehicles monitors engine oil pressure and signals the dashboard light or ECU when it drops. It is an OE replacement, so its calibration follows the original switch.
- Activates the dashboard warning or an ECU input when oil pressure falls below safe operating thresholds
- Alerts the driver or system to low oil pressure to help protect vital engine components
- Calibrated for pressure activation point, thread pitch and electrical response
- Resists high temperatures, oil exposure and vibration in demanding engine environments
