4. Remove the black tester lead from spade terminal
C and connect it to spade terminal A. The meter
should read 4.5-5.5 DC volts.
NOTE: If the meter does not read as specified,
check for poor connections at the ECU or
open/broken wires in the wiring harness.
5. Turn the ignition switch to the OFF position; then
disconnect the battery (negative cable first).
6. Select the OHMS position on the meter; then per-
form the following resistance tests on the TPS.
A. Pin (B) to ground - infinity (open circuit).
B. Pin (A) to pin (B) - approximately 4.8k ohms
(throttle closed).
C. Pin (A) to pin (B) - approximately 4.8k ohms
(throttle full-open).
D. Pin (B) to pin (C) - approximately 4.8k ohms.
E. Pin (B) to pin (C) - approximately 1.2k ohms
(throttle full-open).
FI455A
NOTE: If any meter reading is not as specified,
replace or adjust the TPS (see INSTALL-
ING/ADJUSTING in this sub-section).
7. Connect the positive lead to the battery; then con-
nect the negative lead.
8. Connect the main harness TPS connector to the
TPS; then using MaxiClips, connect the black
tester lead to the black/green wire and the red
tester lead to the green/black wire.
9. Select the DC Voltage position on the meter and
turn the ignition switch to the ON position. The
meter should read approximately 1.12 DC volts
with the throttle full-open and approximately 4.32
DC volts with the throttle in the closed position.
NOTE: If the meter readings are as specified,
check the main harness connector at the ECU
main harness wiring. If the meter readings are not
as specified, replace the TPS and adjust to specifi-
cations (see INSTALLING/ADJUSTING in this
sub-section).
10. Clear all ECU error codes after servicing is com-
plete (see ECU Error Codes in this section).
REMOVING
1. Remove the right-side engine cover; then discon-
nect the three-wire TPS connector plug.
FI450A
2. Remove the screw securing the TPS to the throttle
body and remove the TPS.
INSTALLING/ADJUSTING
1. Place the TPS into position on the throttle body
and secure with the two screws. Do not tighten at
this time.
2. Connect the main harness to the TPS.
! CAUTION
Always make sure the ignition switch is in the OFF
position before disconnecting the ECU.
! CAUTION
Always disconnect the battery when performing
resistance tests to avoid damaging the multimeter.
! CAUTION
Always make sure the ignition switch is in the OFF
position before disconnecting the ECU.
