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 10 seconds before conducting the next test.

Testing condition:

Do not raise engine speed above 3,000 RPM during the DTC confirmation procedure. If the engine speed limit is exceeded, retry the procedure from step 2.
Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

With CONSULT-II

Start engine and warm it up to normal operating temperature.
Select DATA MONITOR mode with CONSULT-II. See Figure .
Hold engine speed at 2,000 RPM and check one of the following.
- HO2S1 (B1)/(B2) voltage should go above 0.70V at least once.
- HO2S1 (B1)/(B2) voltage should go below 0.21V at least once.
  If the check result is NG, perform DIAGNOSTIC PROCEDURE .
  
  If the check result is OK, perform the following step.
Let engine idle at least 5 minutes.
Maintain the following condition at least 50 consecutive seconds.
