Voltage should be 12 V.
If voltage reads 12 V, check continuity of wire
between BLACK wire of relay connector and pin
DA-28 of ECM connector. If faulty, repair/replace
wire/connector. If wire/connector tests good, try
anewECM.
If voltage does not read 12 V, check continuity
of wire on supply side. If faulty, repair/replace
wire/connector. If wire/connector tests good, re-
fer to ELECTRICAL SYSTEM to test output side or
relay.
THROTTLE POSITION SENSOR
(TPS)
General
The throttle position sensor (TPS) is a potentiome-
ter that sends a signal to the ECM which is propor-
tional to the throttle shaft angle.

1. Throttle position sensor (TPS)
IMPORTANT: Prior to testing the TPS, ensure
that mechanical components/adjustments are
adequate according to CARBURETOR in AIR IN-
DUCTION SYSTEM above.
IMPORTANT: Pin-out of TPS harness connector
does not match the TPS sensor pin-out. The pin-
out used in the following tests is the TPS harness
connector pin-out.

The ECM may generate several fault codes per-
taining to the TPS. Refer to SYSTEM FAULT
CODES in DIAGNOSTIC PROCEDURES section
for more information.
Wear Test
While engine is not running, activate throttle and
pay attention for smooth operation without physi-
cal stops of the cable.
Connect vehicle communication kit (VCK) and use
B.U.D.S. software.
Use the Throttle Opening display under Monitor-
ing.
