Troubleshooting
13A-17
Code No.14 Throttle position sensor system (2nd
channel)
Probable cause
The throttle valve controller determines whether a failure is present or not, and sends
a signal indicating its result to the engine-ECU.
Range of check
D
Ignition switch: ON
D
Throttle position sensor (1st channel) is normal
Set conditions
D
The throttle position sensor (1st channel) output voltage is 1.24 V or more, and
the (2nd channel) output voltage is 4.6 V or more for one second.
or
D
The throttle position sensor (1st channel) output voltage is 3.53 V or less, and
the (2nd channel) output voltage is 0.2 V or less for one second.
or
D
Throttle position sensor (1st and 2nd channels) output voltages are outside 4
to 6 V.
D
Malfunction of throttle position sensor (2nd channel)
D
Open circuit or short-circuited harness wire in throttle
position sensor (2nd channel) or poor connector
contact
D
Faulty throttle valve controller
D
Malfunction of the engine-ECU
Check trouble symptom.
NG
Replace the engine-ECU.
NG
Repair
OK
Replace the throttle valve controller.
Check the throttle position sensor. (Re-
fer to P.13A-107.)
NG
Replace
OK

nector A-73.
D
Disconnect the connector, and
measure at the harness side.
D
Voltage 1 and earth
(Ignition switch: ON)
OK:
4.8 - 5.2 V
D
Continuity between 3 and earth
OK:
Continuity
NG
Check the following connector:
B-50
NG

OK
Check trouble symptom.
NG
Check the harness wire between the
throttle position sensor and throttle valve
controller.
OK
NG
Check the following connector:
A-73
NG
Repair
OK

to P.13A-97.)
NG
Repair
OK
Measure at throttle valve controller con-
nector B-50.
D
Connect the connector.
D
Disconnect the throttle control servo
connector (Close the throttle valve
fully by finger).
D
Voltage between 7 and earth
(Ignition switch: ON)
OK:
0.4 - 0.6 V
NG
Check the following connector:
A-73
NG
Repair
OK
Check trouble symptom.
NG
Check the harness wire between the
throttle valve controller and throttle posi-
tion sensor, and repair if necessary.
OK
Replace the throttle valve controller.
Measure at engine-ECU connector
B-51.
D
Connect the connector.
D
Disconnect the throttle control servo
connector (Close the throttle valve
fully by finger).
D
Voltage between terminal 84 and
earth
(Ignition switch: ON)
OK:
4.2 - 4.8 V
