PNP SWITCH
PNP SWITCHPFP:32006
Component DescriptionEBS01AGR
When the shift lever position is P or N, park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.

Diagnostic ProcedureEBS01AGU
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch ON.
2. Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II.
3. Check the “P/N POSI SW” signal under the following conditions.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between ECM terminal 102 and ground under the
following conditions.

INJECTOR CIRCUIT
INJECTOR CIRCUITPFP:16600
Component DescriptionEBS0114I
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.
