1A-21 Engine General Information and Diagnosis:
Example of Trouble
Three data; value 3 (current data 3), value 1 (past data 1) and value 2 (past data 2); can be made in comparison by
showing them in the graph. Read the change of value by comparing the current data to the past data that have been
saved under the same condition, then you may determine how changes have occurred with the passing of time and
identify what problem is currently occurring.
NOTE
With DTC not output, if the engine idling speed and secondary throttle actuator position are found to
be abnormal than the data saved previously, the possible cause may probably lie in the hardware side
such as ISC valve air bypass passage clogged, secondary throttle valve stuck, etc.
Unstable idling speed
Abnormal valve of secondary throttle valve position
No DTC output
