Detected condition and possible cause
Detected condition |
Possible cause |
||
C14 | Output voltage is not within the following
range. Difference between actual throttle opening and opening calculated by ecm is larger than specified value. 0.2 V ≤ Sensor voltage < 4.8 V |
|
|
P0120 | H | Sensor voltage is higher than specified value. |
|
L | Sensor voltage is lower than specified value. |
Wiring diagram
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” . |

If check result is not
satisfactory, replace tp
sensor with a new one. Refer to “throttle body disassembly and assembly” in section 1d . |
Regulator / rectifier inspection

Disassembly
Remove the fuel tank. Refer to “fuel tank removal and installation” .
Remove the fuel pump assembly (1) by removing its
mounting bolts diagonally.
Spilled gasoline should be wipe off
immediately.
Keep away from fire or spark.
