Hint
: hand–held tester only: narrowing down the trouble area is possible by performing ”a/f control” active test (heated oxygen sensor or other trouble areas can be distinguished).
Hint
: ”a/f control” is the active test which changes the injection volume to –12.5 % Or +25 %.
Result:
heated oxygen sensor reacts in accordance with increase and decrease of
injection volume
+25 % " rich output: more than 0.5 V,
–12.5 % " Lean output: less than 0.4 V
Notice
: there is a delay of few seconds in the sensor 1 (front sensor) output, and there is about 20 seconds delay at maximum in the sensor 2 (rear sensor).
The following of a/f control procedure enables the technician to check and graph the voltage outputs of both the heated oxygen sensors.
For displaying the graph indication, enter ”active test / a/f control / user data”, then select ”o2s b1s1 and o2s b1s2” by pressing ”yes” button and push ”enter” button before pressing ”f4” button.
Hint
:
1 Check other dtc output(in addition to dtc p0136)
Result:
Hint
: if any other codes besides p0136 are output, perform the troubleshooting for those dtcs first.
2 Read value of hand–held tester or obd ii scan tool(output voltage of heated oxygen sensor)
Hint
: quickly accelerate the engine to 4,000 rpm 3 times by using the accelerator pedal.
Standard: the output voltage of heated oxygen sensor (sensor 2): alternates from 0.4 V or less to 0.5 V or more.
3 Inspect heated oxygen sensor(heater resistance)
Standard:
4 Inspect efi relay
Standard:
5 Check harness and connector(heated oxygen sensor – ecm)
Standard (check for open):
Standard (check for short):
Replace heated oxygen sensor
6 Perform confirmation driving pattern
Hint
: clear all dtcs prior to performing the confirmation driving pattern.
7 Read output dtc(dtc p0136 is output again)
Result:
Replace heated oxygen sensor
Inspection procedure
1 Check seat position air bag sensor
Sst 09843–18040
Turn the ignition switch to on, and wait at least for 20 seconds.

Circuit description
When the ignition switch is turned on, battery positive voltage is applied to
the coilwhich closes the contacts
of the efi main relay (marked: efi) and supplies power to terminal +b of the ecm.
This signal causes current to flow to the coil, closing the contacts of the efi
relay and supplyin ...
