DTC DETECTION LOGIC AND CONDITIONS
EHU010200000103
• The following DTCs have been adopted detection condition.
— P0116, P0134, P0137, P0411, P050A
• The following DTCs have been changed detection condition.
— P0030
• Detection conditions are shown below.
P0030 Front HO2S heater control circuit problem
• The PCM monitors the front HO2S impedance when under the front HO2S heater control for 190 s. If the
impedance is more than 44 ohms while PCM turns front HO2S heater on, the PCM determines that there is a
front HO2S heater control circuit problem.
P0116 Engine coolant temperature circuit range/performance
• The PCM monitors the maximum value and minimum value of engine coolant temperature when the engine is
started and 5 min have been passed after leaving the vehicle 6 h or more. If difference between maximum and
minimum values of engine coolant temperature is below 5.6 °C {42.1 °F} the PCM determines that there is an
ECT circuit range/performance problem.
