Scan Gauge WT Reading
I purchased a ScanGauge ll and one of the factory settings is coolant temp. (WT)
It never moves off of 40 degrees F. Is there a code I can enter in the X gauge?
Thanks in advance, Bill

IIRC, the ScanGauge just reads coolant temp from the OBSII port, and isn't accurate in the auto models. Same with the oil temp in the manual trucks.

mine did the same thing, but -40 if I read it right.
I found a post that listed this code to use.
once water temp reaches 150 degrees it reads right, something about being in 2 or 3 stages - but it's the best i've found so far. stays within 5 degrees of oil once things are warmed up.
Engine Coolant Temp:
TXD: C410F1221139
RXF: 046205110639
RXD: 3008
MTH: 00010002007F
NAM: ect

good deal. I really enjoy the SGII. was displaying mpg avg and instant on one side, oil and tranny on the other. now that I have oil working swapped that in place of tranny for regular driving

Just watch your oil temp. It's accurate, and more important in the long run anyway. That's what I do.

Like Clay said, if your truck is an auto, you can't read coolant temps. Reason being is there is no PCM input for coolant temps on truck equipped with automatic transmissions. Since the scan gauge reads from the PCM, it's going to give erroneous numbers. Oil temps are what you want to track.

There is a coolant temp sensor, but it's wired directly to the dash gauge and not to the PCM. Since the Scangauge connects to the OBDII port and pulls data from the PCM, it has no input for coolant temps.
