Review on 🚗 ESUPPORT Car 2" 52mm Digital Oil Temperature Gauge with Blue LED Light - Automotive Temperature Meter by Aaron Vang

Bought coolant temp, oil pressure and voltage sensors. I wrote a review for the temperature sensor but I couldn't see the others. OIL PRESSURE - seemed to work on the Autobahn until a few days ago. Suddenly read 0! Removed, checked level and allowed to cool. When I restarted it it rose to 60psi and slowly dropped to 0. The car was at home on a flat surface. I will install a mechanical sensor to determine if it is a sensor or a motor and let you know. VOLTAGE. The good news is that the sensor showed overvoltage. The bad news is that when measured with a voltmeter it's 1/2 volt. If it was a Winton return window I would return them all. As it is I will accept the loss of money.
