10. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
11. If idle speed and ignition timing are not within the specification, the result will be incomplete. In this case, find the cause of the problem by
referring to the "Diagnostic Procedure" below.
DIAGNOSTIC PROCEDURE
If idle air volume learning cannot be performed successfully, proceed as follows:
1. Check that throttle valve is fully closed.
2. Check PCV valve operation.
3. Check that downstream of throttle valve is free from air leakage.
4. When the above three items check out OK, engine component parts and their installation condition are questionable. Check and eliminate the
cause of the problem.
It is useful to perform, "TROUBLE DIAGNOSIS SPECIFICATION VALUE".
5. If any of the following conditions occur after the engine has started, eliminate the cause of the problem and perform "Idle air volume learning" all
over again:
-
Engine stalls.
-
Erroneous idle.
