oxygen sensors and 21A4 obd command

[mitsos4all]

hi

car: Megane II LM1S
instrument panel: the orange engine symbol lights up and the message "check emissions" appears

reply of 17FF00

7E8 10 14 57 06 01 36 DF 01
7E8 21 36 41 01 41 DF 01 41
7E8 22 61 03 00 DF 03 13 DF

four DTCs: 0136, 0141, 0300, 0313 -> downstream oxygen sensor (after catalyser), misfires

reply of 21A4

7E8 10 1B 61 A4 5C 00 00 00
7E8 21 00 00 00 2F 00 02 00
7E8 22 00 00 00 45 26 00 15
7E8 23 5D 34 9D 2D 60 21 DB

according to file of ECM (S3000_AD_CAN_3_X84ph2_S.json)
byte 3-> 5C=92 -> 898mV voltage of upstream oxygen sensor
byte 10 -> 2F=47 -> 459mV voltage of downstream oxygen sensor
bytes 6,7 -> 0000 -> 0 ohms of upstream oxygen sensor heater
bytes 13,14 -> 0000 -> 0 ohms of downstream oxygen sensor heater

I test the command 21A4 in my friend Scenic II, no DTCs found, and the reply is similar to above
I get 0 ohms to heater of both oxygen sensors.

I want to ask you, what is the way to read the heater resistance by 21A4 command?

I do not try the diagnostic routines OBD SAV by these commands: 31080003, 31080103
if someone has a reply from the above please post here

as regards the fault
before six months I replace the coils with new ones (Valeo)
I remove the coils and spark plugs, these were slightly moist, after a good cleaning
and refitting them, I erase the DTCs with 14FF00 command
the orange engine symbol did not come on again
