INSPECTION

PROCEDURE

1. INSPECT REAR CENTER ULTRASONIC SENSOR

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

Standard Resistance:

Tester Connection

Condition

Specified Condition

4 (BI) - 6 (EI)

Always

10 kΩ or higher

4 (BI) - 1 (BO)

Always

Below 1 Ω

5 (SI) - 2 (SO)

Always

Below 30 Ω

6 (EI) - 3 (EO)

Always

Below 1 Ω

If the result is not as specified, replace the rear center ultrasonic sensor.

DESCRIPTION The air fuel ratio sensor (sensor 1) generates current that corresponds to the actual air fuel ratio. This sensor current is used to provide the ECM with feedback so that it can control the air fuel ratio. The ECM determines the deviation from the stoichiometric air fuel ratio level, and
