Detected condition and possible cause
Detected condition |
Possible cause |
|
C44/P0130 | Ho2 sensor output voltage is not input to
ecm during engine operation and running
condition. Sensor voltage > 1.0 V |
|
C44/P0135 | The heater can not operate so that heater operation voltage is not supplied to the oxygen heater circuit. |

Troubleshooting (when indicating c44/p0130:)
Caution when using the multi-circuit tester, do not strongly touch the terminal of the ecm coupler with a needle pointed tester probe to prevent terminal damage. |
Note after repairing the trouble, clear the dtc using sds tool. Refer to “use of sds diagnosis reset procedures” . |

Front brake light switch inspection
Inspect the front brake light switch in the following
procedures:
disconnect the front brake light switch coupler (1).
Inspect the front brake light switch for continuity with
the tester.
If any abnormality is found, replace the front brake light switch with a new
one. Re ...
