(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.
