OK
(d) Turn the Techstream on.
(e) Enter the following menus: Powertrain / Engine and ECT / Data List / Intake Air.
(f) Read the value displayed on the Techstream.
OK:
Difference between the intake air temperature and the actual outside air temperature is within 10°C
(18°F).
HINT:
Temperature readings on the vehicle outside temperature gauge (if equipped) are not suitable for
comparison with the IAT reading. The outside temperature gauge has a significant delay built-in to prevent
temperature swings from being displayed on its display. Use an accurate thermometer to determine the
outside air temperature.
Perform "Inspection After Repair" after replacing the mass air flow meter

READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / All Data / Coolant Temp.
(e) Read the value displayed on the Techstream.
OK:
The difference between the coolant temperature and the actual outside air temperature is within 10°C
(18°F).
HINT:
If the result is not as specified, check if there are heat sources such as a block heater in the engine
compartment.

increases. The ECM calculates the throttle valve opening angle according to these signals and controls the throttle
actuator in response to driver inputs. These signals are also used in calculations such as air-fuel ratio correction,
power increase correction and fuel-cut control.
