Keep an early eye on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1018, an OE-replacement sensor that monitors oil pressure and signals the ECU or dashboard warning light when pressure falls below safe operating thresholds. It's a direct-fit replacement across a wide Chrysler, Dodge, Jeep, Ram, SRT and Volkswagen application list, including the 2011-2016 Chrysler 200, 2005-2016 Chrysler 300, 2006-2016 Dodge Charger, 2008-2016 Dodge Challenger, 2011-2016 Ram 1500 and 1999-2001 & 2014-2016 Jeep Cherokee — see the "Vehicles it fits" section for the full list and engine details.
- Monitors oil pressure: activates the dashboard warning or ECU input when oil pressure drops below safe operating levels.
- OE-replacement calibration: matches original specs for pressure activation point, thread pitch, and electrical response.
- Exact OE fit: threads into the factory location using original threads and connectors, with no modifications required.
- Built for harsh conditions: made to resist high temperatures, oil exposure, and vibration in demanding engine environments.
If a failed pressure switch is the cause of a flickering oil light, false warnings, or a missing signal under actual low-pressure conditions, this unit restores that early-warning function. Suitable for scheduled service, a drivability repair, or an engine rebuild.
Frequently Asked Questions
What does this switch do?
It monitors engine oil pressure and activates the dashboard warning light or sends a signal to the ECU when pressure falls below safe operating thresholds, providing early warning of low-oil conditions.
Will the 256-1018 fit my vehicle?
It's a direct-fit replacement for a wide range of Chrysler, Dodge, Jeep, Ram, SRT and Volkswagen models. Check the "Vehicles it fits" section to confirm your exact year, make, model and engine.
What are signs this 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, since low readings can have other sources.
Where does it install?
It threads into the factory location using the original threads and connectors, typically the engine block or oil filter housing, and connects to existing wiring with no modifications required.
Is this an OE-replacement part?
Yes. It's an OE-replacement switch calibrated to match original specifications for pressure activation point, thread pitch, and electrical response.
