Notes On Intermittents

Manipulate affected wiring and connectors while observing ECM parameter code "ED02". Apply and release vacuum to MAP sensor vacuum port using a vacuum source. If ECM parameter code "ED02" displays less than 17 KPA, condition has been induced and cause of intermittent can be repaired. Code "EO32" can be set by:

• Open 5 volt reference between ECM and sensor.
• Open MAP signal between sensor and ECM.
• Defective MAP sensor.
