TYPICAL ENABLING CONDITIONS
Monitor runs whenever following DTCs are not present
ES
Battery voltage
IAT
ECT
Atmospheric pressure
Idle
Engine RPM
A/F sensor
Fuel system status
Engine load
All of the following conditions 1, 2 and 3 are met:
1. MAF
2. Front catalyst temperature (estimated)
3. Rear catalyst temperature (estimated)
EVAP system monitor
A/F sensor monitor
Rear HO2S monitor
Shift position
TYPICAL MALFUNCTION THRESHOLDS

MONITOR RESULT
Refer to CHECKING MONITOR STATUS (See page ES-25).
CONDITIONING FOR SENSOR TESTING
Perform the operation with the engine speeds and time durations described below prior to checking the
waveforms of the A/F and HO2 sensors. This is performed in order to heat the sensors sufficiently to
obtain the appropriate inspection results.
