AIR FUEL RATIO SENSOR INSPECTION

  1. INSPECT AIR FUEL RATIO SENSOR (for Bank 1)

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

      A011QRPE32
      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-) - 10 kΩ or higher
