INSPECTION
PROCEDURE
1. INSPECT AIR FUEL RATIO SENSOR (for Bank 1)
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
1 (HA1A) - 2 (+B) |
20°C (68°F) | 1.6 to 3.2 Ω |
1 (HA1A) - 4 (A1A-) |
Always | 10 kΩ or higher |
If the result is not as specified, replace the air fuel ratio sensor. |
