Procedure"

 .

Overall Function Check

UBS00DHZ

Use this procedure to check the overall function of the heated oxygen sensor 1 circuit. During this check, a
DTC might not be confirmed.

 WITH GST

1.

Start engine and warm it up to normal operating temperature.

2.

Set voltmeter probes between ECM terminal 50 [HOS1 (B1) sig-
nal] or 51 [HOS1 (B2) signal] and engine ground.

3.

Check the following with engine speed held at 2,000 rpm con-
stant under no load.

The voltage fluctuates between 0 to 0.3V and 0.6 to 1.0V more
than 5 times within 10 seconds.

4.

If NG, go to 

EC-783, "Diagnostic Procedure"

 .

Specification data are reference values and are measured between each terminal and ground.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
