INSPECTION PROCEDURES FOR DIAGNOSIS CODES
Code No. 13, 14 Accelerator pedal position sensor (APS)
If the APS output voltage (APS opening voltage) is 4.8 V or higher when the engine
is idling, the output voltage is judged to be too high and diagnosis code No. 13
is output. If the APS output voltage (APS opening voltage) is 0.335 V or lower
when the engine is idling, the output voltage is judged to be too low and diagnosis
code No. 13 is output.
If the APS output voltage (APS power supply voltage) is 3.0 V or lower or if it
is 5.7 V or higher when the engine is idling, the APS is judged to be faulty and
diagnosis code No. 14 is output.
Accelerator pedal position sensor
check (Refer to GROUP 13A ± On-ve-
hicle Service.)
OK
Check the following connectors:
<L.H. drive vehicles> C-46, C-25, D-34,
D-04
<R.H. drive vehicles> C-46, C-26, D-34,
D-04
OK
Check the trouble symptoms.
Code No. 15, 16 A/T fluid temperature sensor system
If the A/T fluid temperature sensor output is 10 ° C or less (5.6 k Ω or more) even
after running the engine for 15 minutes or more, it is judged that there is an open
circuit in the A/T fluid temperature sensor and diagnosis code No. 15 is output.
If the A/T fluid temperature sensor output is 240 ° C or more (10 Ω or less), it is
judged that there is a short circuit in the A/T fluid temperature sensor and diagnosis
code No. 16 is output.
A/T fluid temperature sensor check
