Engine coolant temp. sensor location on 92 GMC 2.5L 4 cyl.?

My 92 GMC Sonoma PU is running poorly. Failed to start for quite a while recently (turned over but did not fire). The “check engine light” came on. I read the code and it said 15, which according to my Haynes manual is the “engine coolant temp. sensor”. My manual gives the location for some models, but not the 2.5 4 cyl.

Where might this sensor be located?

Autozone has a repair guide for your truck. Here’s the location of the sensor
