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.

NGEC0115
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted,
always turn ignition switch OFF and wait at least 5 seconds before
conducting the next test.
TESTING CONDITION:
쐌 Always perform at a temperature above −10°C (14°F).
쐌 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) Stop engine and wait at least 5 seconds.
3) Turn ignition switch ON and select “HO2S1 (front) P0132” of
“HO2S1 (front)” in “DTC WORK SUPPORT” mode with CON-
SULT-II.
4) Touch “START”.
5) Start engine and let it idle for at least 3.0 minutes.
NOTE:
Never raise engine speed above 3,000 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 dis-
played on the CONSULT-II screen. Maintain the conditions
continuously until “TESTING” changes to “COMPLETED”. (It
will take approximately 50 seconds or more.)
