DTC DETECTING CONDITION AND TROUBLE AREA
1. To ignition switch 3. Fuse box
2. HO2S-1 4. ECM (PCM)
DTC DETECTING CONDITION TROUBLE AREA
Following conditions are detected in idle state while running
under driving conditions described for “DTC Confirmation
Procedure”.
P0130 (LOW VOLTAGE)
• 4.5 V or more HO2S circuit voltage is detected, when 5 V
power is connected to HO2S circuit in ECM (PCM), or
• Max. output voltage of HO2S is 0.6 V or lower on average
and its minimum voltage on average is 0.3 V or lower.
(2 driving cycle detection logic)
P0130 (HIGH VOLTAGE)
• Min. output voltage of HO2S is over 3.0 V or
• Max. output voltage of HO2S is 0.74 V or higher on aver-
age and its min. voltage on average is 0.33 V or higher.
(2 driving cycle detection logic)
• HO2S-1 or its circuit
• Fuel system
• ECM (PCM)
