The Oil Pressure Sender is a BOSCH Porsche 918 Spyder engine monitoring component designed to measure engine oil pressure and transmit accurate pressure readings to the vehicle's engine management system and instrument cluster. As a critical part of the lubrication monitoring system, the oil pressure sender helps ensure that the engine maintains adequate oil pressure for proper lubrication, cooling, and protection of internal components.
Fits:

Diagram Ref No 7
This BOSCH sensor is engineered for precise pressure measurement, reliable signal transmission, and long-term durability in demanding engine environments. It continuously monitors oil pressure levels, allowing the driver and ECU to detect lubrication issues before they can cause serious engine damage.
What This Product Does:
- Measures engine oil pressure in real time
- Transmits oil pressure data to the ECU and dashboard
- Monitors lubrication system performance
- Triggers oil pressure warnings when pressure falls outside specification
- Helps protect critical engine components from lubrication failure
- Supports overall engine reliability and performance
Symptoms Of Wear Or Failure:
- Oil pressure warning light illuminated Erratic or fluctuating oil pressure readings
- Incorrect low oil pressure warnings
- Oil pressure gauge not functioning correctly
- Check engine light or related fault codes
- Oil leaks around the sender unit
- Intermittent sensor operation or signal loss
- False warnings despite normal oil pressure levels
Why Replacement Matters:
- Restores accurate oil pressure readings
- Ensures reliable warning system operation
- Helps detect genuine lubrication problems early
- Prevents false warning messages and unnecessary diagnostics
- Supports proper engine lubrication monitoring
- Protects internal engine components from damage caused by low oil pressure
- Maintains confidence in the vehicle’s engine management and monitoring systems
- Contributes to long-term engine reliability and performance

Engine oil pressure sender / switch
Mounted on the cylinder head, this component monitors pressure within the engine lubrication system and supplies the corresponding signal for the dashboard oil-pressure display and warning system.
Fits:
Porsche 996 Carrera 3.4L / 3.6L 1998 - 2005
Porsche 997 Carrera 3.6L / 3.8L 2005 - 2008
Diagram Ref No 32. (Cylinder Head)
Functions
- Monitors engine oil pressure
- Provides information to the dashboard pressure gauge
- Supports the low oil-pressure warning system
- Helps identify potentially unsafe lubrication conditions
Technical Details
- Brand: OE Match
- Porsche cross-reference: 99660620303
- Installation position: cylinder head
- Diagram location: cylinder head, reference number 32
Symptoms of Fault
- Oil-pressure gauge readings that fluctuate unexpectedly
- Gauge momentarily dropping to zero before recovering
- Warning light flickering at idle despite the correct oil level
- Pressure display remaining unusually high or low
- Intermittent readings associated with heat or vibration
- Oil seepage around the sender body or connection
Why Replacement Matters
A defective sender may produce inaccurate readings or false dashboard warnings. However, low oil pressure can also indicate a genuine lubrication fault, so the engine oil level and actual pressure should be checked before the sender is assumed to be the cause. A mechanical pressure test is the preferred method of confirming the engine's true oil pressure.
FAQs
- Does a flickering oil warning always mean the sender has failed?
No. Treat any oil-pressure warning as genuine until the oil level and actual pressure have been checked. - How can the sender be diagnosed?
Inspect the electrical connection and wiring, then compare the displayed reading with a mechanical oil-pressure gauge. - Should a leaking sender be replaced?
Yes. Seepage from the sender body or seal can worsen and allow oil to contaminate nearby components.
