•
DTCs P0136 and P0156 indicate the deterioration of
the HO2 sensor. The ECM sets the DTCs by
calculating the impedance of the sensor when the
typical enabling conditions are satisfied (1 driving
cycle).
•
DTCs P0137 and P0157 indicate an open or short
circuit in the HO2 sensor (1 driving cycle). The ECM
sets the DTCs when the impedance of the sensor
exceeds the threshold of 15 k
Ω
.
