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
How to proceed with troubleshooting
The hand–held tester can be used at step 4, 6, 8 and 9.
1 Vehicle brought to workshop
2 Customer problem analysis
3 Warning light check
4 The dtcs check (present and past dtcs)
5 The dtcs chart
6 Circuit inspection
7 Repair
8 Clear the dtcs (present and past dtcs)
9 The dtcs ...
When stopping the engine with the shift lever in a position other than P (vehicles
with a continuously variable transmission)
If the engine is stopped with the shift lever in a position other than P, the
engine switch will not be turned off but instead be turned to ACCESSORY mode. Perform
the following procedure to turn the switch off:
1 Check that the parking brake is set.
2 Shift the shift lever to P.

Adjustment
1. Check and adjust brake pedal height
Inspect brake pedal height.
Pedal height from asphalt sheet:
m/t: 134.9 – 144.9 Mm (5.311 – 5.703 In.)
A/t: 136.0 – 146.0 Mm (5.353 – 5.747 In.)
Disconnect the connector from the stop lamp
switch.
Remove the stop lamp switch. ...
