1988 Ford Bronco 4.9 Y, Standard, M5OD-R2SECTION Notes

To prevent replacement of good components, be aware that the following non-EEC related areas may be at fault: person testing EEC system did not perform brief Wide Open Throttle (WOT) after Dynamic Response code, mechanical engine problems, or engine did not go over 2000 RPM.

NOTE: If throttle is snapped open briefly it may not pass the WOT test. Ensure that the throttle is depressed fully to WOT and that engine exceeds 2000 RPM.
