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” . |

Special tool Tester knob indication continuity test ( )
Special tool Tester knob indication continuity ( ) Ecm couplers (harness side) Is the continuity ok? |
Go to step 2. | W/g wire shorted to the power source, or w/g or b/br wire open. |

Special tool Tester knob indication voltage ( ) Ho2 sensor output voltage at idle speed 0.3 V and less ((+) terminal: w/g (b) – (–) terminal: b/br (gr))
Ho2 sensor output voltage at 5 000 r/min 0.6 V and more ((+) terminal: w/g – (–) terminal: b/br) Is the voltage ok? |
|
Replace the ho2
sensor with a new one. Refer to “ho2 sensor removal and installation” in section 1c . |

Open circuit check
Possible causes for the open circuit are as follows. As
the cause can exist in the connector/coupler or terminal,
they need to be checked carefully.
Loose connection of connector/coupler.
Poor contact of terminal (due to dirt, corrosion or rust,
poor contact tension, entry of f ...
Combination meter inspection
Led inspection
Check that the leds “a” (fi, fuel, engine rpm, oil
pressure/engine coolant, immobilizer (e-02, 19, 24, 51)
and meter panel illumination) immediately light up when
the ignition switch is turned on.
Check that the other leds “b” (neutral, high-beam and
turn signal indicator ligh ...
