Wideband Calibration
Current Issue on 1/5/2006
I wanted to verify my wideband calibration again just to be sure.
I followed the instructions for wbo2 calibration in the Userguide.
board sent out status:
Board version =v3.3
serial=374
pump-=4.00V (I don't know what these values mean?Can I check them?)
pump_pw_zero=0x64(this one is OK)
pump+=3.93V
Measurements:
- wbo2_pump_pw_zero=0x64 reads 0,02V across pin 5-6
- with wbo2 disconnected I've put 2 100 Ohm resistors between pin 1-6 and pin 1-5, I enabled wbo2 heater and waited till the W changed into a P on page mlp07 but no O2 reading showed! Then I measured with DVM across ground and pin1 = 4,57V. Because it should be around 4.41V I changed wbo2_nernst_dc_target=9C into 99 and restarted the board but nothing changed(still 4.57V)?
In fact, between nernst and pump-: 0.45V +- 0.03 V is OK
Are you sure about EC18pin.. wbo2pin.. connections ?yes it seems that I have a correct wbo2 reading while driving
Can you restate the above with EC18 pins instead of wbo2 pins ?will try that
Did you issue mde02 to enable WBO2 ?yes, there is a W and an On showing when I issue this command and after a few seconds the W changes inta a P
Also publish (Man)mcd config-dump so the wbo2_nernst_dc_target and other wbo2... variables can be verified (as in the controller).
Air calibration
wbo2_calibration=DA when O2% shows 20.9
