Keep an accurate eye on engine oil pressure with the Beck/Arnley Engine Oil Pressure Switch 201-2004 (also written 2012004). This oil pressure switch monitors oil pressure and triggers the dashboard oil pressure warning light, and it drops in as a direct-fit replacement for the 2009-2013 Mazda 6, 2001-2009 Mazda B2300, 1998-2001 Mazda B2500, 1998-2007 Mazda B3000, 1999-2009 Mazda B4000, and 2007-2015 Mazda CX-9. See the Buyer’s Guide tab for the full engine-level fitment.
- OE form, fit & function: Engineered to match the original switch on the listed foreign-nameplate applications.
- Quality materials: Made with high-quality material and componentry.
- Built to last: High-quality construction for durability in service.
- Engine-ready: Constructed to withstand an engine environment and application-specific for these vehicles.
The switch threads into an engine oil passage and reads oil pressure; when pressure drops below its setpoint it closes the circuit to illuminate the warning light. If a faulty switch is the cause of a stuck-on or non-working oil light — or you see oil weeping from the switch — this replaces it. Diagnose the underlying cause before assuming the switch has failed.
