It’s a direct-fit replacement across a broad Honda and Acura range, including the 2008-2022 Honda Accord, 2006-2014 and 2017-2022 Honda Civic, 2015-2020 Honda Fit, 2009-2022 Honda Pilot, 2014-2020 and 2022 Acura MDX, and 2015-2022 Acura TLX — see the Buyer’s Guide tab for the full list of applications and engines.
- Monitors oil pressure: Activates the dashboard warning or ECU input when oil pressure drops below safe operating thresholds.
- Helps prevent engine damage: Alerts the driver or system to low-oil-pressure conditions so vital components can be protected.
- OE-replacement calibration: Matches original specifications for pressure activation point, thread pitch, and electrical response.
- Built for harsh conditions: Made with high-temperature and oil-resistant materials to resist heat, oil exposure, and vibration.
Designed for an exact OE fit, it threads into the factory location using the original threads and connectors with no modifications required. Signs the original switch may need replacing include a flickering oil light, false warnings, or no signal under actual low-pressure conditions.
