INSPECTION

PROCEDURE

1. INSPECT HEATED OXYGEN SENSOR

(a) for Bank 1:

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

1 (HT1B) - 2 (+B)

20°C (68°F)

11 to 16 Ω

1 (HT1B) - 4 (E2)

Always

10 kΩ or higher

If the result is not as specified, replace the heated oxygen sensor.
