Oxygen sensor circuit
Description
In order to obtain a high purification rate of the carbon monoxide (co),
hydrocarbon (hc) and nitrogen
oxide (nox) components in the exhaust gas, a twc is used. For the most efficient
use of the twc, the
air-fuel ratio must be precisely controlled so that it is always close to ...
Different diameter tire malfunction
Description
The skid control ecu measures the speed of each wheel by receiving signals
from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly.
Therefore, all wheel
signals must be equal.
Inspection procedure
Check tire size
