Detected condition and possible cause
Detected condition |
Possible cause |
||
C29 | Output voltage is not within the following
range. Difference between actual throttle opening and opening calculated by ecm is larger than specified value. 0.15 V ≤ Sensor voltage < 4.85 V |
|
|
P1654 | H | Sensor voltage is higher than specified value. | |
L | Sensor voltage is lower than specified value. |

Troubleshooting
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” . |
