INSPECTION CHART FOR DIAGNOSIS CODES
Code
P1704 Throttle position sensor system
If the TPS output voltage is 4.8V or higher
when the engine is idling, the output is judged
to be too high and diagnosis code P1704 is set.
P1703
If the TPS output voltage is 0.2V or lower at
times other than when the engine is idling, the
output is judged to be too low and diagnosis
code P1703 is set. If the TPS output voltage is
P1702
0.2V or lower or if it is 1.2V or higher when the
engine is idling, the TPS adjustment is judged
to be incorrect and diagnosis code P1702 set.
P0713 Fluid temperature sensor system
If the fluid temperature sensor output voltage is
4.57V or more even after driving for 10 minutes
or more (if the fluid temperature does not
P0712
increase), it is judged that there is an open
circuit in the fluid temperature sensor and
diagnosis code P0713 is set.
P0725 CKP sensor system
If no output pulse is detected from the crank
shaft position sensor for 5 seconds or more
while driving at 25 km/h or more, it is judged
that there is an open circuit in the crank shaft
position sensor and diagnosis code P0725 is
set.
P0715 Input speed sensor system
If no output pulse is detected from the input
shaft speed sensor for 1 second or more while
driving in 3rd or 4th gear at a speed of 30 km/h
or more, there is judged to be an open circuit or
short circuit in the input shaft speed sensor and
diagnosis code P0715 is set. If diagnosis code
P0715 is set four times, the transmission is
locked into 3rd gear (D range) or 2nd gear as a
fail-safe measure.
P0720 Output speed sensor system
If the output from the output shaft speed sensor
is continuously 50% lower than the vehicle
speed for 1 second or more while driving in 3rd
or 4th gear at a speed of 30 km/h or more,
