Diagnostic Aids
WARNING: This page is about a different car, the 1995 Ford Explorer and 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.
To prevent replacing good components, be aware the following non-EEC related areas may be cause of problem:
- Technician did not perform brief Wide Open Throttle (WOT) after Dynamic Response Code.
- Engine did not go over 2000 RPM during WOT. This test is only intended to diagnose:
- Throttle movement (minimum 3/4 throttle).
- RPM increase is more than 2000 RPM.
If throttle is snapped open briefly, it may not pass WOT test. Ensure throttle is depressed fully to WOT and engine speed exceeds 2000 RPM.
