From the 97 FSM'*:
P0102 - MAF Sensor Circuit Low Frequency
Normal operating range of MAF is 2000 Hertz at idle up to 10,000 Hertz at max. engine load.
P0102 will set if if the signal frequency from MAF sensor is lower than the possible range of a normally operating MAF sensor.
Conditions for setting P0102:
- Engine is running
- TP angle less than 50%
- System Voltage greater than 8 volts
- MAF signal frequency is less than 1200 Hertz
- Above conditions present for longer than 0.5 seconds + 400 3X reference periods (133 crankshaft revolutions).
