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 contamina-
tion, broken pins, and/or corrosion.
2. Make sure the ignition switch is in the OFF posi-
tion; then select the DC Voltage position on the
meter.
3. Connect the black tester lead to terminal A and the
red tester lead to terminal B. Turn the ignition
switch to the ON position. The meter should read
4.5-5.5 DC volts.
