2.2.7.9 Data Stream List
By reading the "Data Stream List" on the scan tool, you can check switches, sensors, actuators working state without removing any
parts. Before the control system diagnosis, observing and analyzing data is the first step, so that the diagnose time could be
shortened.
Note
Data under normal conditions is listed in the following table for reference only. Do not determine whether a part is faulty
solely based on these reference values. Under normal circumstances you can compare the vehicle that needs to be
repaired with a normal working vehicle in the same state to determine the current vehicle diagnostic data is normal or
not.
1. Run the engine to reach normal working temperature.
2. Turn the ignition switch to "OFF" position.
3. Connect the scan tool.
4. Turn the ignition switch to "ON" position.
5. Select "Engine"/"Read data stream".
6. Refer to the table and check all the data.

The scan tool shows -40°C (-40 ºF) to 130°C
(266 ºF). After heating, sensor (internal
resistance decreases) voltage signal reduces.
ECM will interpret the reduced voltage signal as
engine warmed up. This signal is one of the
conditions used to determine whether to activate
the closed-loop fuel system control, and also an
important injection timing reference signal.

After engine is turned off, it shows 110 steps.
Warmed vehicle idling state, it is typically about
30 to 45 steps. The number of steps increases as
the load increases like Air-Conditioning turned
on, up to 70 steps. With the increase in vehicle
mileage, the stepper motor opening will increase.
After cleaning the stepper motor and the intake
air channel next to the throttle body, the steps will
not decrease during the startup. But the engine
speed will increase.

Throttle position sensor voltage is the voltage
Measure by ECM. While the angle is calculated
according to voltage. When at idle, the voltage is
0.3-0.9V. With full-throttle the voltage is
4.25-4.7V. The voltage increases as the throttle
opening increases. The self learn value will
become larger and larger when the throttle body
is dirty and move up the zero value. After cleaning
the throttle, the computer will automatically re-
learn.
