Description

INFOID:0000000004362541

Electric throttle control actuator consists of throttle control motor,

throttle position sensor, etc. The throttle position sensor responds to

the throttle valve movement. 

The throttle position sensor has two sensors. These sensors are a

kind of potentiometers which transform the throttle valve position into

output voltage, and emit the voltage signal to the ECM. In addition,

these sensors detect the opening and closing speed of the throttle

valve and feed the voltage signals to the ECM. The ECM judges the

current opening angle of the throttle valve from these signals and the

ECM controls the throttle control motor to make the throttle valve

opening angle properly in response to driving condition.

DTC Logic

INFOID:0000000004211482

DTC DETECTION LOGIC

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank-

shaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.

The misfire detection logic consists of the following two conditions.
1. One Trip Detection Logic (Three Way Catalyst Damage) 

On the 1st trip, when a misfire condition occurs that can damage the three way catalyst (TWC) due to

overheating, the MIL will blink.

When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions

for a change.

When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.

If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.

When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.

If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.

2. Two Trip Detection Logic (Exhaust quality deterioration)

For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only

light when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sen-

sor signal every 1,000 engine revolutions.

A misfire malfunction can be detected on any one cylinder or on multiple cylinders.
