Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Functional description
The engine oil pressure/temperature sensor measures the absolute pressure of the engine oil and its temperature. The measured values are output as a pulse-width-modulated signal.
The measuring procedure is based on a micromechanical piezoresistive pressure sensor (silicon) which supplies an output signal proportional to the pressure. Temperature measurement is performed by way of a diode.
The sensor measuring range is 0.5 bar to 10.5 bar at permissible temperatures between -40 °C and 160 °C. The sensor is operated with a voltage of 5 V.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
