Hello Its been a while.
I just installed a rebuilt Quad-4 HO and went back to $8B. I kept getting the ses light after start up so i watched the data stream and seen the temp sensor reading 250+ degrees F until the engine temp gets to 121 F then reads normal to at least 192F. I checked the engine with a laser thermometer and the sensor boss temp was the same as the data stream. I tested a new sensor today by plugging it in without installing in the engine. the outside temps here are 95-100F, the new sensor read 256F while in my hand so i plugged the old sensor back in with the engine running and at 182F and the data stream went back to 182F.

Do i have the wrong type of coolant temp sensor? Did I scramble the code some how, I have had to build history tables and dashboards in the adx, maybe user error? Is there any new developments with $8B?

I always appreciate the advice!!!
