The part number 256-1069 is used where accurate oil pressure feedback is needed to keep the warning system functioning properly.

Key Features

• OE replacement engine oil pressure switch
• Black plastic construction for engine-bay service
• Spade terminal design with 1 connector and 1 terminal
• Matches OE pressure threshold, thread, and electrical response requirements
• Direct-fit replacement for factory mounting locations
• Built for Nissan and INFINITI oil pressure monitoring systems

Detailed Description

Walker Products 256-1069 is engineered to replace the factory engine oil pressure switch used on many Nissan and INFINITI vehicles. It monitors oil pressure and communicates low-pressure conditions to the vehicle’s control system or dashboard warning light. When the original switch fails, drivers may see flickering oil lights, false warnings, or no warning at all during an actual pressure drop. This replacement switch is manufactured to align with OE specifications for thread size, terminal type, and electrical behavior, helping restore proper signal output in the lubrication warning circuit.

Compatible With 2002-2012 Nissan Altima, 2009-2014 Nissan Maxima, 2009-2014 Nissan Murano, 2009-2021 Nissan Frontier, 2007-2012 Nissan Pathfinder, 2003-2008 INFINITI G35, and other listed Nissan and INFINITI applications. The part number 256-1069 is also a direct reference for service lookups on these vehicles.

Common Issues This Part Can Help Solve

• Oil pressure warning light flickering or staying on
• False low-oil-pressure alerts
• No warning signal when oil pressure drops
• Faulty oil pressure switch electrical output
• Intermittent dashboard oil light operation

Installation Notes and Tips

Install the switch in the factory oil pressure switch location, typically on the engine block or oil filter housing, and connect it to the existing wiring without modification. Verify the connector style, terminal layout, and thread match before installation. If the warning light remains on after replacement, inspect the wiring, connector condition, and actual engine oil pressure to confirm system operation.

Quality Assurance

Walker Products manufactures this switch to OE replacement standards using high-temperature, oil-resistant materials for consistent performance in engine service. The design follows factory specifications for fit and electrical response, supporting reliable oil pressure monitoring across the listed Nissan and INFINITI applications.
