Porsche 964 / 993 Oil Pressure & Temperature Sensor Kit – Bosch

The KCPerformance Porsche 964 / 993 Oil Pressure & Temperature Sensor Kit provides a practical solution for monitoring engine oil pressure and oil temperature using a single high-quality Bosch sensor.

Designed for the Porsche 911 964 and 993, this kit combines a Bosch 10-bar oil pressure and 140°C temperature sensor with a specially selected adapter and matching electrical connector. The connector is supplied complete with terminals and wire seals, providing the necessary components for integration into a custom engine wiring harness.

This kit is particularly suitable for Porsche 964 and 993 vehicles equipped with an aftermarket standalone ECU, such as MaxxECU, where accurate oil pressure and temperature measurements are essential for engine monitoring, data logging, and engine protection.

Combined Oil Pressure and Temperature Measurement

The Bosch sensor measures both engine oil pressure and oil temperature in a single compact unit. This eliminates the need for two separate sensors and simplifies the installation of additional engine monitoring equipment.

The sensor provides an analogue voltage signal for oil pressure and a resistance-based signal for oil temperature, allowing both measurements to be connected to compatible standalone engine management systems.

When properly configured, the sensor can provide valuable information for engine diagnostics, performance monitoring, and ECU-based safety functions.

Bosch Oil Pressure and Temperature Sensor

The included Bosch combined sensor features the following specifications:

• Manufacturer: Bosch
• Sensor type: Combined oil pressure and temperature sensor
• Pressure measurement range: 0–10 bar
• Temperature measurement range: -40°C to +140°C
• Sensor thread: M10 × 1.0
• Pressure output: 0.5V at 0 bar to 4.5V at 10 bar
• Temperature output: Resistance-based
• Electrical connection: 5-pin Bosch connector
• Sealing: Stainless steel sealing ring included

Adapter for Porsche 964 and 993

The Bosch sensor uses an M10 × 1.0 thread. To allow installation on the Porsche 964 and 993, this kit includes a suitable adapter.

The adapter allows the combined oil pressure and temperature sensor to be installed in the intended Porsche engine application without requiring a different sensor thread.

This provides a convenient solution for upgrading the oil monitoring system on Porsche 911 964 and 993 engines, particularly when installing a modern standalone ECU.

Matching Bosch Electrical Connector

The kit includes the matching 5-way Bosch electrical connector housing, complete with terminals and wire seals for the combined oil pressure and temperature sensor.

All necessary connector components are included, allowing the connector to be assembled and integrated into a custom engine wiring harness.

This makes the kit suitable for professional installations and custom engine management conversions where the wiring is built specifically for the vehicle.

Please note: Electrical wires and a wiring harness are not included.

Sensor Pinout and Wiring Information

The Bosch sensor uses the following electrical connections:

• Pin 2: Oil pressure signal output (0.5–4.5V)
• Pin 3: +5V sensor supply
• Pin 4: Sensor ground
• Pin 5: Oil temperature signal output (resistance-based)

The oil pressure signal should be connected to a suitable 0–5V analogue input on the ECU.

The oil temperature signal should be connected to a compatible temperature analogue input with a 5V pull-up resistor.

Important: Correct wiring and sensor calibration are required for accurate measurements. Always verify the sensor pinout and ECU input configuration before connecting the sensor.

Ideal for Standalone ECU Applications

The Porsche 964 / 993 Oil Pressure & Temperature Sensor Kit is particularly useful for vehicles equipped with an aftermarket engine management system.

When connected to a compatible ECU, such as MaxxECU, the sensor can provide important engine information for:

• Real-time engine oil pressure monitoring
• Real-time engine oil temperature monitoring
• Engine data logging
• Oil pressure warning functions
• Oil temperature warning functions
• ECU-based engine protection strategies
• Performance tuning and motorsport applications

Depending on the ECU configuration, oil pressure and temperature measurements can be used to activate warning functions or engine protection strategies when predefined limits are exceeded.
