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.

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.
