With CONSULT

OVERALL FUNCTION CHECK
Instead of performing DTC DETECTING CONDITION, the following method can be used for checking the front oxygen sensor function. (The "NG" of the OVERALL FUNCTION CHECK means the same as the DTC detection.)
1. Start engine and warm it up sufficiently.




2. Select "MANU TRIG" and "HI SPEED" in "DATA MONITOR" mode with CONSULT, and select "FRO2 SENSOR" and "FRO2 MNTR".
3. Touch "RECORD" on CONSULT screen with engine speed held at 2,000 rpm constant under no load.
4. Make sure of the following:




- "FR O2 MNTR" in "DATA MONITOR" mode indicates "RICH" and "LEAN" periodically more than 5 times for 10 seconds.
- The maximum voltage of "FR O2 SENSOR" is over 0.6V at least one time.
- The minimum voltage of "FR O2 SENSOR" is below 0.35V at least one time.
