No... the hall effect sensor does not detect flow. It is used to trigger the firing of injectors/spark plugs.The MASS, or MAF(mass air flow) you refere to is not used by Chrysler, at least not in the '80s and early '90s. It is an air flow sensor that basically detects air flow, not temp. Another similar type sensor is the HALL effects sensor. This jewel somehow uses the curvature of the earth to aid and detect flow(don't ask). Our cars have an air charge temp. sensor.
