Conditions For Setting DTC

Passive Tests

• The HO2S voltage for both fuel control sensors is more than 470 mV for 20 seconds, 200 mV for 7 seconds on a warm start while the AIR system is commanded on.
• The HO2S voltage for both fuel control sensors do not toggle above 600 mV for 25 seconds, 7 seconds on a warm start while the AIR system is commanded on.

Active Test

• The AIR passive test is inconclusive or failed.
• The HO2S voltage for both fuel control sensors is more than 250 mV for 3 second active tests.
