Section 1 (Engine Controls - Tests W/Codes): Summary

WARNING: This page is about a different car, the 1993 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.

If no hard trouble codes are present (or only pass trouble codes), driveability symptoms exist or intermittent trouble codes exist, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.) or intermittent procedures.

NOTE: To determine a common cause for a trouble code to be set, see TROUBLE CODE DIAGNOSTIC HINTS table below.
