INSPECT RESISTANCE OF AIR FLOW METER

(a) Disconnect the air flow meter connector.
(b) Using an ohmmeter (analog type), measure the resistance between each terminal.

Terminals          Resistance (Ω)          Temp. °C (°F)
                   10,000 — 20,000         -20 (-4)
                   4,000 — 7,000           0 (32)
THA — E2          2,000 — 3,000           20 (68)
                   900 — 1,300             40 (104)
                   400 — 700               60 (140)

If the resistance is not as specified, replace the air flow meter.

(c) Reconnect the air flow meter connector.
