2. Turn the ignition switch to the ON position. The mul-
timeter should read battery voltage. If battery voltage
is not indicated, check the 30-amp fuse, wiring har-
ness, or the ignition switch.
3. Remove the red tester lead and connect to the blue/
brown wire (B). The multimeter should read approxi-
mately 2.5 DC volts. If the specified voltage is not
indicated, check wire connections at the ECM or sub-
stitute another ECM to verify the test.
OUTPUT VOLTAGE
NOTE: Needle adapters will be required on the mul-
timeter leads as the following tests are made with the
sensor connected.
1. Connect the three-wire plug to the sensor; then
remove the right-side mounting screw securing the
sensor to the frame.
2. Install the needle adapters to the multimeter leads;
then select DC Voltage on the multimeter.
3. Connect the red tester lead to the blue/brown wire (B)
and the black tester lead to the pink/black wire (A);
then turn the ignition switch ON and observe the
meter. The meter should read 0.8-3.0 DC volts.
CD705B
4. Tilt the sensor 60° or more to the left and right observ-
ing the meter. The meter should read 4.0-8.0 DC volts
after approximately one second in the tilted position.
If the meter readings are not as specified, the tilt sen-
sor is defective.
NOTE: When replacing the sensor after testing
make sure the arrow is directed up.

Throttle Position Sensor
(TPS)
NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the
LCD gauge (see EFI Diagnostic System in this sec-
tion).
TESTING
1. Remove the seats and rear body panel; then
remove the two top radiator mounting cap screws
and tilt the radiator rearward to access the throttle
body. Remove the TPS connector plug from the
TPS.
WC206C
NOTE: Prior to testing the TPS, inspect the three-
wire plug connector on the main harness and the
three-pin plug on the TPS for contamination, broken
pins, and/or corrosion.
NOTE: If the vehicle is in warranty, removing or
adjusting the TPS will void warranty. If the TPS is
tested out of specification, the throttle body must be
replaced. If the vehicle is out of warranty, the TPS can
be adjusted.
2. Connect the TPS Multi-Analyzer Harness connec-
tor #8 to the TPS; then connect the harness to the
TPS Analyzer Tool.
