DTC Confirmation ProcedureCAUTION:
Always drive vehicle at a safe speed.
TESTING CONDITION:
Never stop engine during this test. If the engine is stopped, reperform this test from step 2 in "Procedure for COND1".
NOTE:
If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test. "COMPLETED" will appear on CONSULT screen when all tests "COND1", "COND2" and "COND3" are completed.
With CONSULT
Procedure for COND1:
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 5 seconds.
3. Turn ignition switch "ON" and select "RR 02 SEN-B1 (-B2) P0137 (P0157)" of "REAR 02 SENSOR" in "DTC WORK SUPPORT" mode with CONSULT.
4. Touch "START".
5. Start engine and let it idle for at least 30 seconds.
6. Rev engine up to 2,000 rpm 2 or 3 times quickly under no load. If "COMPLETED" appears on CONSULT screen, go to step 2 in "Procedure for COND3". If "COMPLETED" does not appear on CONSULT screen, go to the following step.
7. Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
8. When the following conditions are met, "TESTING" will be displayed at "COND1" on the CONSULT screen. Maintain the conditions continuously until "TESTING" changes to "COMPLETED". (It will take approximately 60 seconds.)
NOTE:
If "TESTING" is not displayed after 5 minutes, retry from step 2 in "Procedure for COND1".
If "COMPLETED" already appears at "COND2" on CONSULT screen before "Procedure for COND2" is conducted, it is unnecessary to conduct "Procedure for COND2".
Procedure for COND2
1. While driving, release accelerator pedal completely with "OD" OFF from the above condition (step 8) until "INCOMPLETE" at "COND2" on CONSULT screen has turned to "COMPLETED". (It will take approximately 4 seconds.)
Procedure for COND3
1. Stop vehicle and let it idle until "INCOMPLETE" of "COND3" on CONSULT screen has turned to "COMPLETED". (It will take a maximum of approximately 6 minutes.)
2. Make sure that "OK" is displayed after touching "SELF-DIAG RESULTS". If "NG" is displayed, refer to "Diagnostic Procedure".
Overall Function Check
Use this procedure to check the overall function of the rear heated oxygen sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Without CONSULT
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeter probes between ECM terminal 56 (right bank sensor signal) or 57 (left bank sensor signal) and engine groijnd.
4. Check the voltage when racing up to 4,000 rpm under no load at least 10 times. (depress and release accelerator pedal as soon as possible) The voltage should be below O.54V at least once during this procedure. If the voltage can be confirmed in step 4, step 5 is not necessary.
5. Keep vehicle at idling for 10 minutes, then check the voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in 3rd gear position (M/T), "D" position with "OD" OFF (NT).
The voltage should be below O.54V at least once during this procedure.
6. If NG, go to "Diagnostic Procedure".
Component Inspection
REAR HEATED OXYGEN SENSOR
With CONSULT
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Select "FUEL INJECTION" in "ACTIVE TEST" mode, and select "RR O2 SEN-B1 (-B2)" as the monitor item with CONSULT.
4. Check "RR 02 SEN-Bi (-B2)" at idle speed when adjusting "FUEL INJECTION" to +/- 25%.
"RR 02 SEN-Bi (-B2)" should be above O.56V at least once when the "FUEL INJECTION" is +25%.
"RR 02 SEN-Bi (-B2)" should be below O.54V at least once when the "FUEL INJECTION" is -25%.
Without CONSULT
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeter probes between ECM terminal 56 (right bank sensor signal) or 57 (left bank sensor signal) and engine ground.
4. Check the voltage when racing up to 4,000 rpm under no load at least 10 times. (depress and release accelerator pedal as soon as possible)
The voltage should be above O.56V at least once during this procedure.
If the voltage is above O.56V at step 4, step 5 is not neccessary.
5. Keep vehicle at idling for 10 minutes, then check the voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in 3rd gear position (M/T), "D" position with "OD" OFF (A/T).
The voltage should be below O.54V at least once during this procedure.
CAUTION:
Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
