DTC P0102: Volume Airflow Circuit Low Input: Operation
The VAF sensor power is supplied from the MFI relay (terminal No. 4), and the ground is provided on the ECM (terminal No. 40 - M/T) or PCM (terminal No. 16 - A/T). A 5-volt power is applied to the VAF sensor output terminal (terminal No. 3) from the ECM (terminal No. 90 - M/T) or PCM (terminal No. 65 - A/T). The VAF sensor generates a pulse signal when the output terminal and ground are opened/closed (open/short).
