Temp gauge sender Ohm values.

Post by BlackBetty » Wed May 16, 2018 9:58 pm

Hi all,
Does someone have the Ohm values for the dash coolant temp sensor? I did find the ones for the blue (ECU) sensor, 3-400 at operating temp, but can not find anything on the other sensor.. got some funny things going on with my coolant temp..actually, I do not get any Ohm value on that sensor, including a short , however the gauge does kinda work, pulling the connector off and shorting it out does leave the gauge at cold....however the gauge does go up and down starting and driving.. just runs hot .. new radiator and thermostat, recent pump and clutch and hoses..

This is on a '88 with a -B35 running Motronic 1.3
