Manufactured using high-quality automotive-grade electronic components with a precision pressure-sensitive diaphragm, oil-resistant seals and a durable corrosion-resistant housing, the oil pressure switch is engineered to withstand continuous exposure to hot engine oil, pressure fluctuations, vibration and demanding operating conditions. Designed for direct OE-style installation, it restores reliable oil pressure monitoring and seamless integration with the factory electrical and lubrication systems.
What This Product Does:
- Continuously monitors engine oil pressure.
- Sends accurate oil pressure signals to the vehicle's warning system.
- Activates the oil pressure warning light when pressure falls below specification.
- Helps protect the engine from lubrication-related damage.
- Supports reliable engine health monitoring.
- Assists with early detection of lubrication system faults.
- Restores factory oil pressure monitoring performance.
- Forms an essential part of the engine lubrication and electrical monitoring system.
Symptoms Of Wear Or Failure:
- Illuminated oil pressure warning light.
- Intermittent or flickering oil pressure warning light.
- False oil pressure warnings despite normal oil pressure.
- Engine management or oil pressure-related fault codes.
- Oil leaking through or around the pressure switch.
- Erratic or incorrect oil pressure readings.
- Oil contamination within the electrical connector.
- Corrosion or damage to the switch body.
- Failure of the warning light to operate correctly.
- Difficulty diagnosing genuine lubrication system faults.
Why Replacement Matters:
- The oil pressure switch operates continuously whenever the engine is running, where it is exposed to hot engine oil, high pressure, vibration and repeated thermal cycling. Over time, the internal pressure diaphragm, seals and electrical contacts can wear or deteriorate, resulting in inaccurate readings, intermittent operation or oil leakage.
- A faulty oil pressure switch can trigger false warning lights, leading to unnecessary diagnostic work, or fail to warn of a genuine loss of oil pressure. Without an accurate warning system, the engine may continue operating with insufficient lubrication, potentially causing accelerated wear or catastrophic engine damage.
- Replacing a worn or faulty oil pressure switch with the OE Match Oil Pressure Switch restores dependable oil pressure monitoring and ensures the engine warning system operates as intended. Manufactured to OE standards using premium-quality materials, it provides factory-style fitment, accurate performance and long-lasting durability, helping safeguard your Porsche engine and maintain the reliability and peace of mind expected from a properly functioning lubrication system.

Oil Pressure Sender Unit
The Oil Pressure Sender Unit is a critical engine monitoring
component fitted to the Porsche 911 SC from 1978 to 1983. Designed to
continuously monitor engine oil pressure and transmit accurate readings to the
dashboard gauge, this sender unit allows drivers to keep track of one of the
most important indicators of engine health.
Fits:
- Porsche 911 1978-1983 3.0L / SC
Diagram ref no 45
On air-cooled Porsche engines, maintaining correct oil pressure is essential for lubrication, cooling, and long-term engine protection. The oil pressure sender unit converts oil pressure into an electrical signal that is displayed on the instrument cluster, providing real-time feedback on the condition of the lubrication system.
A faulty sender unit can result in inaccurate readings, fluctuating gauge behaviour, or complete loss of oil pressure indication, making replacement an important part of preventative maintenance and engine reliability.
What Does the Oil Pressure Sender Unit Do?
The oil pressure sender measures the pressure generated within the engine's lubrication system and sends a corresponding electrical signal to the oil pressure gauge.
This enables the driver to:
- Monitor engine oil pressure in real time
- Identify lubrication issues before serious damage occurs
- Detect low oil pressure conditions
- Verify correct oil circulation throughout the engine
- Monitor engine health during normal driving and performance use
Because the Porsche 911 SC uses an air-cooled engine with a sophisticated dry-sump lubrication system, accurate oil pressure readings are particularly important for protecting valuable engine components.
Why Does the Oil Pressure Sender Unit Fail?
Oil pressure sender units operate in a harsh environment exposed to heat, vibration, oil contamination, and age-related deterioration.
Common causes of failure include:
- Internal electrical wear
- Diaphragm deterioration
- Oil contamination inside the sender
- Corrosion of electrical terminals
- Heat-related degradation
- Vibration damage Internal sealing failure causing oil leaks
- Age-related sensor inaccuracy
As the sender ages, readings may become erratic, inaccurate, or completely non-functional.
Common Symptoms of a Faulty Oil Pressure Sender
A failing oil pressure sender unit may cause:
- Oil pressure gauge fluctuating unexpectedly
- Incorrect oil pressure readings
- Gauge reading permanently high or low
- Intermittent gauge operation
- No oil pressure indication at all
- Oil leakage from the sender body
- Dashboard oil pressure concerns despite normal engine operation
In many cases, the sender unit itself is the source of the problem rather than the engine's oil pressure system.
When Should You Replace It?
Replacement is recommended when:
- Oil pressure readings become unreliable
- The gauge behaves erratically
- The sender develops an oil leak
- During engine restoration work
- When replacing ageing engine sensors
- As part of preventative maintenance on high-mileage vehicles
- During diagnosis of oil pressure-related dashboard faults
Replacing a faulty sender restores confidence in your oil pressure monitoring system and helps ensure that genuine lubrication issues can be identified quickly.
