Notes On Intermittents
If an intermittent code EO67 is being set, manipulate related wiring while observing ECM inputs EI83 and EI84. If failure is induced, reading will jump from "LO" to "HI" with the switch off (not depressed). This code can also be set by vehicle owner if the cruise "ON/OFF" switch is turned on, or the "ON/OFF" switch was left on when ignition is turned on and the owner was depressing either the "SET/COAST" or "RESUME/ACCEL" switches.
Review snapshot data parameters stored with this code to verify failure. If failure is verified, check and repair intermittent wiring connections or sensor.
