Diagnostic Aids: Notes

Perform this test only when directed by QUICK TEST.

To prevent replacing good components, be aware that the following non-EEC related areas may be the cause of problem:

• Technician testing EEC system did not perform brief Wide Open Throttle (WOT) after Dynamic Response Code.
• Faulty mechanical engine components
• Engine did not go over 2000 RPM during WOT

This test is intended to diagnose only the following:

• Throttle movement (minimum 3/4 throttle)
• RPM increase is greater than 2000 RPM

If throttle is snapped open briefly, it may not be sufficient to pass WOT test. Ensure throttle is depressed fully to WOT, and engine speed exceeds 2000 RPM.
