PNP SWITCH
2.
CHECK PNP SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch “OFF”.
2.
Disconnect PNP switch harness connector.
3.
Check harness continuity between PNP switch terminal 2 and
body ground. Refer to Wiring Diagram.
4.
Also check harness for short to power.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3. (M/T models)
NG
>> Repair open circuit or short to power in harness or con-
nectors. (A/T models)
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors M71, F45
●
Harness for open or short between Park/Neutral position (PNP) switch and ground
>> Repair open circuit or short to power in harness or connectors.
4.
CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Disconnect ECM harness connector.
2.
Check harness continuity between ECM terminal 102 and PNP switch terminal 1.
Refer to Wiring Diagram.
3.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 6.
NG
>> GO TO 5.
5.
Check the following.
●
Harness connectors M112, F73 (A/T models)
●
Harness connectors M71, F45 (M/T models)
●
Harness for open or short between Park/Neutral position (PNP) switch and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
6.
CHECK PNP SWITCH
Refer to
(A/T models) or “PNP SWITCH”, MT-17 (5MT) (M/T models).
OK or NG
OK
>> GO TO 7.
NG
>> Replace PNP switch.
7.
CHECK INTERMITTENT INCIDENT
Refer to
EC-644, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"
.
>> INSPECTION END

INJECTOR CIRCUIT
PFP:16600
Component Description
EBS00R3M
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the injector circuit, the coil in the injector is
energized. The energized coil pulls the needle valve back and allows
fuel to flow through the injector into the intake manifold. The amount
of fuel injected depends upon the injection pulse duration. Pulse
duration is the length of time the injector remains open. The ECM
controls the injection pulse duration based on engine fuel needs.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
