Issue: code c195 or low saturated evap refrigerant temp
Hooked up the gauges and Cooper strap on temp sensor to suction line at compressor and found suction line sensor reading 16 degrees lower than my strap on. Fired up compressor and watched ODM reading plumet to -15 while Cooper strap on never went below 50.
Ohmed out both sensors and the 1st time I hit the suction line sensor it was jumping from about 52k to as low as 3.5k. Tested to ground, no shorts. About the 3rd time I hooked up the leads it leveled out to 10k which is right on the money with my temp readings. Checked wire for rubs or shorts, none found.
So my question is can this sensor short with oil in the line that is migrating? Have you ever seen a sensor that shorts in a given temp range? What else could factor into this thing giving wild ohm/temp readings?
I should also add that I changed the paired sensors a week ago, last one was reading 135 degrees static.
