(B136) No. 5 (+) — Chassis ground (–):
Does the voltage change by
shaking the ECM harness and
connector while monitoring the
value of voltage meter?
Repair poor con-
tact in ECM con-
nector.
Go to step 6.
6CHECK OUTPUT SIGNAL OF ECM.
1) Disconnect the connector from rear oxygen
sensor.
2) Measure the voltage between ECM con-
nector and chassis ground.

7CHECK REAR OXYGEN SENSOR.
1) Turn the ignition switch to OFF.
2) Measure the resistance between rear oxy-
gen sensor connector terminals.
Te r m i n a l s
No. 1 — No. 2:
Is the resistance less than 30
Ω?
Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following item:
•Open circuit
of harness be-
tween rear oxy-
gen sensor and
ECM connector
•Poor contact
in rear oxygen
sensor connec-
tor
•Poor contact
in ECM connec-
tor
•Poor contact
of coupling con-
nector
