Notes On Intermittents

Code EO32 can be set by an open 5-volt reference signal between ECM and sensor, an open MAP signal between sensor and ECM, or a defective MAP sensor.

Manipulate affected wiring and connectors while observing ECM parameter ED02. Apply and release vacuum to MAP sensor vacuum port using a vacuum source. If ECM parameter ED02 displays less than 17 kPa, condition has been induced and cause of intermittent can be repaired. If wiring and connectors are okay, substitute a known good sensor and re-test.

Review snapshot data parameters stored with this code to verify failure. If failure is verified, check and repair intermittent wiring connection or sensor.
