Tested on an RX3 that is running well with no errors
Testing the procedure for P031/P032 , O2 voltage high/low (page 52-53)
Firstly, the O2 connector is labelled correctly
step2,
"use a test light", on page 14 it suggest to use a test light that draws no more than 0.3A, I found a bulb rated 3W for the job. It draws 0.26A.
It Illuminated as brightly as when connected directly to the battery.
(stated - Illuminates brightly)
step3,
12.16 v ( a bit low
) , (stated range 12.2-13.5v)
step4,
" connect to J2-17", this is not possible as it is plugged in to the ECU. I tested point "C" on the O2 sensor connector, it connects directly to "J2-17".
4.78v (stated range 4.20v- 4.95v)
step5,
4.74v (stated range 4.20v- 4.95v)
