How does the car data flow look normal?

When reading the engine data stream, some Volkswagen models are displayed in the form of data group numbers. Each group number has four display areas, and the data in each display area has its own meaning.

Display group number 00 (or 000)

1. Coolant temperature: the normal value is 170~204 (equivalent to 80 ~105 C).

2. Engine load: the normal value is 20~50 (equivalent to 1~2.5ms).

3. Engine speed: the normal value is 70~90 (equivalent to 700 ~ 900 rpm).

4. Battery voltage: the normal value is 146~2 12 (equivalent to 10~ 14.5V).

5. Throttle angle: the normal value is 0~ 12 (equivalent to 0 ~ 5).

6. Idle air quality control value: the normal value is 1 18~ 138 (equivalent to -2.5~+5kg/h).

7. Measured idle air quality: the normal value is 1 12~ 144 (equivalent to -4.0~+4.0kg/h).

8. Control value of mixture composition (λ control value): the normal value is 78~ 178 (equivalent to-10~+ 10%).

9. Measured value of mixture composition (λ measured value): the normal value is115 ~141(equivalent to 0.64~6.4ms).

10. Measured value of mixture composition (λ measured value): normal value 1 18~ 138 (equivalent to -8~8%).

Display the group number 0 1 (or 00 1)

1. Engine speed: the normal idle speed is 800±30 rpm. Check the idle speed if it exceeds the specified value.

2. Engine load: at idle speed, the normal value is 1.00 ~ 2.50 ms; if it is less than 1.0ms, it may be that there is a leak in the intake system; Fuel system pressure is too high

3. Throttle angle: the normal value at idle speed is 0 ~ 5. If it is greater than 5, it may be that the throttle control part J338 has not undergone basic system adjustment; The throttle cable is too tight and needs to be adjusted; Damage to throttle control component

4. Ignition advance angle: the normal value at idle speed is12 4.5 (BTDC). If it is less than 12 (BTDC), the engine load is too large.

Display group number 02 (or 002)

1. Engine speed: the normal idle speed is 800±30 rpm. If the idle speed exceeds the specified value, check it.

2. Engine load: at idle speed, the normal value is 1.00 ~ 2.50 ms; if it is less than 1.00ms, it may be that there is a leak in the air intake system; Fuel system pressure is too high

3. Fuel injection time of the engine per cycle: the normal value is 2.0~5.0ms at idle speed. If it is less than 2.0ms, the exhaust ratio of the carbon canister purification system may be too high; If it is greater than 5.0 milliseconds, the engine load is too large.

4. Intake air quality
