Oil Pressure Sensor

Post by RedLiner » Thu Dec 19, 2019 9:52 am

After getting spurious readings for oil pressure on my 1993 SL500, the gauge stopped working altogether.

The problem was of course the oil pressure sensor that is located under the oil filter housing.
Out of interest I opened the sensor to see what was what, and was surprised to find an electromechanical device.
The resistance coil was burnt and open circuit at one end. I was tempted to put a blob of solder to complete the circuit but instead found a new original part on eBay for much less than the MB dealer price.

All now fitted and working well ;)
