When
ignition timing according to the air density. The
intake air temperature is also compared with the
ECT to identify the start up of the heating wire of
the heated oxygen sensor and diagnosis of
14°C (57.2 ºF)
evaporative emissions from cold start.
10°C (50 ºF) Varies as the ambient temperature changes.
1. Equal to atmospheric pressure when engine
0.71 V is turned off.
2. Voltage first reduced and then increased
when pressing the acceleration pedal hard.
3. After engine is turned off, the data stream
260 kPa (38 psi)
shows the pressure is close to atmospheric
pressure, voltage close to 5 V.
29.4 g/s
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
93 step
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
0.70 V
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
14.06%
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
2%
the throttle, the computer will automatically re-
learn.
