TEST OR INSPECTION
1. Check sensor.
(b) Disconnect wiring harness from brake
1. If diagnostic code changed from CID
pedal position sensor (WP 0075 00).

replace brake pedal position sensor (WP
2. If diagnostic code remains, go to Test 2.
2. Check wiring harness.
(a) Sensor remains disconnected from
(b) Turn battery disconnect and engine
start switches to OFF position (TM 5-
(c) Disconnect wiring harness connectors
from powertrain ECM (WP 0063 00).
(d) At wiring harness connector for sensor, 1. If resistance is greater than 5,000 Ohms,
measure resistance between signal

contact 3 (wire G746-WH) and frame
procedure. If failure is not found,
replace powertrain ECM (WP 0063 00).
there is a short between frame ground
and signal circuit in wiring harness.
Replace wiring harness in question (WP
0195 00 thru WP 0201 00).
