Hella 007393001 Engine Oil Pressure Switch PSA Diesel

The Hella 007393001 is a direct-fit replacement engine oil pressure switch engineered to monitor oil pressure within the engine's lubrication circuit and protect against low-pressure conditions that can cause serious engine damage.

How It Works:

The oil pressure switch is installed directly in the engine's oil circuit. It operates on a normally closed contact design — when the ignition is switched on, the oil pressure warning light illuminates. Once the engine starts and adequate oil pressure builds, the switch contact opens, interrupting the ground signal and extinguishing the warning light. If oil pressure drops to a dangerous level during operation, the switch closes again and reactivates the warning light on the dashboard.

Key Features:

• OE-Grade Quality: Manufactured by Hella, a globally trusted original equipment supplier to major automotive manufacturers
• Normally Closed Contact Design: Supports effective oil pressure control and engine safety monitoring
• Diesel & Turbodiesel Application: Designed specifically for PSA-platform diesel and turbodiesel engines
• Corrosion-Resistant Construction: Built to withstand the harsh thermal and chemical environment of the engine bay
• Direct Replacement Fit: Engineered to match OEM specifications for hassle-free installation
• Aftermarket OE Parity: The same Hella quality found in original equipment applications, made available for the independent aftermarket

The Hella 007393001 oil pressure switch is a reliable, cost-effective solution for restoring proper oil pressure monitoring and warning functionality to your vehicle's engine management system.
