4. Remove the red tester lead from terminal B and
connect it to terminal A. The meter should read 0
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 1.22k ohms
(throttle closed).
C. Pin (A) to pin (B) - approximately 4.36k ohms
(throttle full-open).
D. Pin (A) to pin (C) - approximately 4.05k ohms.
PR535A
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 tes-
ter 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 0.60 DC volt
with the throttle closed and approximately 4.0 DC
volts with the throttle in the full-open 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 (EFI) in this section).
REMOVING
1. Remove the left-side engine cover; then discon-
nect the three-wire TPS connector plug.

2. Remove the two screws securing the TPS to the
throttle body and remove 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 resis-
tance tests to avoid damaging the multimeter.
CAUTION
Always make sure the ignition switch is in the OFF
