• Remove cover and disconnect throttle cable from
throttle cam.
• With engine off, back out air flow screw until it no
longer is in contact with throttle plate cam. The throttle
plate should seal off throttle bore completely.
Back Air Flow Screw Out Until No
Contact is Made
• Open and close throttle plate a couple of times to ensure
full throttle closing. Do not snap closed, as this could
cause unnecessary throttle plate to throttle body
interference and/or damage.
• Set up the TPS Test Adapter Harness (PU-47082)
according to the instructions. Verify that the 9 volt
battery is new. Figure 2.

• Using a voltmeter attached to the TPS Tester Harness
(PU-47082), check the voltage output of the TPS. It
should read .528 ± .01 volts.
• If it does not read .528 ± .01 volts, loosen the screw
holding the TPS to the throttle body. Rotate TPS until
voltmeter reads .528 ± .01 volts.
• Retighten TPS mounting screw, and verify the voltage
did not change. If changed, repeat the previous steps.
Should Read: .528 V

STEP 2
Establishing correct flow: Now that the zero offset voltage has
been set, you can now set the throttle body to the correct air flow
value.
• With voltmeter still attached to the TPS Test Adapter
Harness (PU-47082), turn the air flow adjustment
screw until the voltmeter reads .710 ± .01 volts. The
throttle body is now adjusted to the correct flow value
