ON-BOARD DIAGNOSTIC
01–02–9
01–02
P0134 Front HO2S no activity detected
The PCM monitors the front HO2S element impedance when the following conditions are met. If the front
HO2S element impedance is 50 ohms or more, the PCM determines that front HO2S is not activated.
MONITORING CONDITIONS
HO2S, HO2S heater and TWC Repair Verification Drive Mode
Following conditions are met
Time from engine start is above 40 s (ECT when engine start is 20 °C {68 °F}).
P0137 Rear HO2S circuit low input
The PCM monitors input voltage from rear HO2S. If the input voltage from the rear HO2S is below 0.1 V for
35.2 s the PCM determines that circuit input is low.
MONITORING CONDITIONS
HO2S, HO2S heater and TWC repair verification drive mode
Following conditions are met.
Engine speed is above 1,500 rpm.
Engine coolant temperature is above 70 °C {158 °F}.
Fuel injector control in rear HO2S closed loop control.
The PCM monitors the input voltage from the rear HO2S when the following conditions are met. Under the
following monitoring conditions, if the input voltage from the rear HO2S does not even exceed 0.1 V though
the short term fuel trim is controlled, the PCM determines that sensor circuit input is low.
P0411 Secondary air injection system incorrect upstream flow
The PCM monitors the front HO2S output current when the Secondary air injection system is operating. If the
output current is less than the specification, the PCM determines that there is a Secondary air injection system
problem.
P050A Cold start idle air control system performance
The PCM monitors actual idle speed while fast idle up correction operating. If the idle speed is out of specified
range, the PCM determines that the idle air control has performance problem.
