NOTE

The A/C system will store DTC B1479 when a voltage value between 0.7 and 4.2 V is displayed continuously for more than 8.0 minutes.

^

If the flow sensor value does NOT change when switching the A/C system/blower ON and OFF and is stuck between 0.7 and 4.0 V go to step 4.

^

If the flow sensor voltage is normal go to step 3 (wire harness check).

3. Check the harness and connector (A/C compressor flow sensor - A/C amplifier).
