AIR FUEL RATIO SENSOR - INSPECTION

1. INSPECT AIR FUEL RATIO SENSOR

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

Standard Resistance (for Bank 1):
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

Standard Resistance (for Bank 2):
Tester Connection Condition Specified Condition
1 (HA2A) - 2 (+B) 20°C (68°F) 1.6 to 3.2 Ω
1 (HA2A) - 4 (A2A-) Always 10 kΩ or higher
