CHECK FOR CURRENT DTC
Note: It is important to perform the diagnostics on the O2 Sensor
that set the DTC.
Note: Check for contaminates that may have damaged the O2
Sensor: contaminated fuel, unapproved silicone, oil and coolant.
Note: If the PCM detects and stores a DTC, the PCM also stores
the engine/vehicle operating conditions under which the DTC was
set. Some of these conditions are displayed on the DRB III at the
same time the DTC is displayed.
Note: Before erasing stored DTCs, record these conditions.
Attempting to duplicate these conditions may assist when check-
ing for an active DTC.
Turn the ignition on.
With the DRB III , erase PCM DTCs.
Note: It maybe necessary to road test the vehicle for this DTC to set.
