CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-

If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 9 seconds
before conducting the next test.

signal is not input, the ECM circuits will read a continuous approxi-
mately 0.3V. Therefore, for this diagnosis, the time that output
voltage is within 200 to 400 mV range is monitored, and the diag-
nosis checks that this time is not inordinately long.

before conducting the next test.
TESTING CONDITION:
+Before performing the following procedure, confirm that
battery voltage is more than 11V at idle.
With CONSULT-II
1) Start engine and warm it up to normal operating temperature.
2) Select ªHO2S1 (B1) P0130º of ªHO2S1 (B1)º in ªDTC WORK
SUPPORTº mode with CONSULT-II.
3) Touch ªSTARTº.
4) Let it idle for at least 3 minutes.
NOTE:
Never raise engine speed above 3,200 rpm after this step. If
the engine speed limit is exceeded, return to step 4.
5) When the following conditions are met, ªTESTINGº will be dis-
played on the CONSULT-II screen. Maintain the conditions
continuously until ªTESTINGº changes to ªCOMPLETEDº. (It
will take approximately 10 to 60 seconds.)
