When the gear position is “P” (A/T models only) or “N”, park/neutral position (PNP) switch is “ON”.
ECM detects the position because the continuity of the line (the “ON” signal) exists.

Diagnostic ProcedureEBS00KLU
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 CIRCUITPFP:16600
Component DescriptionEBS00KLV
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.
