yeah. I wish there is an easy way through MMCD.
Something you can do is measure it by the 0-5 Volts. then calculate the A/R from
Lc-1 website (2 page)

The default analog outputs are as follows: Analog output one (yellow) is 1.1V = 14 AFR and .1V = 15 AFR. This is a simulated narrowband signal. Analog output two (brown) is setup as 0V = 7.35 AFR and 5V = 22.39 AFR.

Per example=
2.5V should be 14.87
BRAINSTORM:
Something I saw in the Chilton book, is that EGR Temperature (In california's car) input is a variable resistance.
I wish I know what are the range values of the sensor.
According to
MMCD is this -2.7x + 597.7 in F
As I said early in the thread: what volts are equal to what Temperature or raw data, to do an easy conversion formula.
BTW the part number is MD131905
