UNITS EHU000000000103
Conversion to SI Units (Système International d'Unités)
•All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted
from these values.
Rounding Off
•Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit
value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.
Upper and Lower Limits
•When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is
an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI
unit value may differ after conversion. For example, consider 2.7 kgf/cm2in the following specifications:
210—260 kPa {2.1—2.7 kgf/cm2, 30—38 psi}
270—310 kPa {2.7—3.2 kgf/cm2, 39—45 psi}
•The actual converted values for 2.7 kgf/cm2are 265 kPa and 38.4 psi. In the first specification, 2.7 is used as
an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is
used as a lower limit, so the converted values are rounded up to 270 and 39.

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.
