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. |
Wiring diagram
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” . |
