1. CHECK AIR FUEL RATIO COMPENSATION SYSTEM

(a) Connect the intelligent tester to the DLC3.

(b) Turn the ignition switch to the ON position.

(c) Select the following menu items: Data List / A/FS B1 S1 and O2S B1 S2.

(d) Warm up the A/F sensor with the engine speed at 2500 rpm for approximately 2 minutes.

(e) Keep the engine speed at 2500 rpm and confirm that the "A/FS B1 S1" and "A/FS BS S1" display is as shown in the illustration.

CHECK AIR FUEL RATIO COMPENSATION SYSTEM

HINT:

Standard

NOTICE: The A/F sensor has an output delay of a few seconds.

(f) Confirm that the "O2S B1 S2" and "A/FS BS S1" display changes between 0 to 1 V with the engine speed at 2500 rpm.

OK: The voltage output oscillates more than 8 times in 10 seconds.

NOTICE:
  • Perform the check immediately after warming the engine up.
  • If the voltage variation could not be verified, warm up the A/F sensor again. If it could not be verified even after warming up the sensor again, check for DTCs (See page ES-39).
