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.
