ON BOARD DIAGNOSIS LOGIC
To judge the malfunction, the output from the heated oxygen sen-
sor 1 (front) is monitored to determine whether the “rich” output is
sufficiently high. The “lean” output is sufficiently low. When both the
outputs are shifting to the rich side, the malfunction will be
detected.

DIAGNOSTIC TROUBLE CODE CONFIRMATION
PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting
the next test.
TESTING CONDITION:
I
Always perform at a temperature above −10°C (14°F).
I
Before performing following procedure, confirm that bat-
tery voltage is more than 11V at idle.
1) Start engine and warm it up to normal operating tem-
perature.
2) Stop engine and wait at least 5 seconds.
3) Turn ignition switch “ON” and select “HO2S1 (B1)
P0132, (B2) P0152” of “HO2S1” in “DTC WORK SUP-
PORT” mode with CONSULT-II.
4) Touch “START”.
5) Start engine (TCS switch “OFF”) and 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 5).
6) When the following conditions are met, “TESTING” will
be displayed on the CONSULT-II screen. Maintain the
conditions continuously until “TESTING” changes to
“COMPLETED”. (It will take approximately 50 seconds.)
CMPS-RPM (POS): 1,200 - 2,200 rpm
Vehicle speed: 0 - 100 km/h (0 - 62 MPH)
B/FUEL SCHDL: 1.4 - 5.0 ms
Selector lever: Suitable position
