Note On Intermittents

If an intermittent Code 44 is being set, manipulate related wiring while observing engine data parameter .0.7 at part throttle with the engine warm. If the failure is induced, the "oxygen sensor" reading will change from its normal fluctuating voltage (above .60 and below .30) to a reading never going above .50 volts. This will help to isolate the location of the malfunction.
