DTC detecting condition
Trouble area
DTC P0137:
HO2S-2 voltage is lower than 0.4 V for more than specified time
continuously while vehicle is driving with high engine load (high speed).
And HO2S-2 max. voltage minus HO2S-2 min. voltage is less than 0.2 V
for specified time continuously.
(2 driving cycle detection logic)
DTC P0138:
HO2S-2 voltage is higher than 0.85 V for more than specified time
continuously while vehicle is driving with high engine load (high speed).
And HO2S-2 max. voltage minus HO2S-2 min. voltage is less than 0.2 V
for specified time continuously.
(2 driving cycle detection logic)
• HO2S-2
• HO2S-2 circuit
• Fuel system
• ECM
• Fuel shortage
• Exhaust system
• Air intake system
