Hella 007393001 Engine Oil Pressure Switch

Engine Oil Pressure Switch for OE Applications

The Hella 007393001 engine oil pressure switch is a 12-volt, normally closed contact switch built with a bolted mounting style and a single connector. It uses an M16x1.5 thread, a 21 mm spanner size, and a 0.6 bar switch pressure setting for direct oil pressure monitoring in the engine circuit.

As part of Genuine OE from HELLA, this switch is specified for drivers and technicians looking for an OE-style replacement with the correct electrical and mechanical interface. It is a practical choice for oil pressure warning systems on vehicles such as Ford Escort and Ford Sierra applications where the original switch specification matches.

Product Details

The Hella 007393001 is an engine oil pressure switch used to monitor oil pressure and trigger the warning circuit when pressure drops below the specified threshold. Its normally closed contact configuration and 0.6 bar switching point make it suitable for systems that rely on a simple on/off pressure signal rather than a variable sensor output. The OE-focused design supports accurate replacement where the original connector count, thread size, and mounting style must match the factory part. This part number 007393001 is also referenced in cross-application listings for select Ford Escort and Ford Sierra oil pressure switch applications.

Common Issues This Part Can Address

• Oil pressure warning light staying on due to a failed switch
• Intermittent or inaccurate oil pressure warning signals
• Electrical connection issues caused by a worn single-pin switch
• Oil seepage around the switch body or threaded port
• Replacement needs for OE-style Ford Escort and Ford Sierra oil pressure switch applications

Installation Notes and Tips

Confirm the engine uses an M16x1.5 threaded oil pressure switch with a 0.6 bar switching specification before installation. Match the 21 mm hex size, bolted mounting style, and single-connector layout to the original unit. Clean the mounting port, inspect the connector terminal, and verify the warning circuit operation after installation. For fitment-based searches, this part is commonly referenced for Ford Escort and Ford Sierra oil pressure switch replacement needs, and the part number 007393001 should be matched against the original component.
