DETECTED
ITEM
DETECTED FAILURE CONDITION CHECK FOR
C29
STP sensor The sensor should produce following
voltage.
0.15 V sensor voltage < 4.85 V
In other than the above range, C29
(P1654) is indicated.
STP sensor, lead wire/coupler
connection
P1654
H
Sensor voltage is higher than specified
value. STP sensor circuit shorted to
VCC or ground circuit open
L
Sensor voltage is lower than specified
value. STP sensor circuit open or
shorted to ground or VCC circuit
open
C31
Gear
position
signal Gear position signal voltage should be
higher than the following for 3 seconds
and more.
Gear position signal voltage 0.6 V
If lower than the above value, C31
(P0705) is indicated.
GP switch, wiring/coupler con-
nection, gearshift cam, etc.
P0705
C32/C33
C34/C35
Primary fuel
injector CKP sensor (pickup coil) signal is pro-
duced, but fuel injector signal is inter-
rupted 4 times or more continuously. In
this case, the code C32 (P0201), C33
(P0202), C34 (P0203) or C35 (P0204)
is indicated. Primary fuel injector, wiring/cou-
pler connection, power supply to
the injector
P0201/P0202
P0203/P0204
C36/C37
C38/C39
Secondary
fuel injector Some failure exists in the fuel injector
signal in a high load, high revolution
condition.In this case, the code C36
(P1764), C37 (P1765), C38 (P1766) or
C39 (P1767) is indicated. Secondary fuel injector, wir-
ing/coupler connection, power
supply to the injector
P1764/P1765
P1766/P1767
C40 (P0505)
ISC valve The circuit voltage of motor drive is
unusual. ISC valve circuit open or shorted
to ground
Power source circuit open
C40 (P0506)

idle speed. Air passage clogged
ISC valve is fixed
ISC valve pre-set position is
incorrect
C40 (P0507)
Idle speed is higher than the desired
idle speed. ISC valve hose connection
ISC valve is fixed
ISC valve pre-set position is
incorrect
