5) Loosen screws (1) securing TPS to manifold.

6) Rotate TPS fully clockwise (holding throttle shaft in closed

position). Voltmeter should read .200 - .300. If readout is not

within specifications, adjust TPS to obtain readout of .240 -

.260.

TPI voltage reading shown below.

.135 ± .010 Models with ECM P/N 14632A13 and below.

.250 ± .010 Models with ECM P/N 14632A15 and up and 824003-1

and up.

.250 ± .050 Models with ECM P/N 14632A16 and up.

IMPORTANT: If engine appears to run too rich or too lean, TPI

can be readjusted. Decreasing voltage yields leaner mixture.

Increasing voltage yields richer mixture. Allowable TPS range:

.200 - .300 volts.

7) Tighten TPI screws to 20 lb. in. (2.0 N· m) holding correct

tolerance.

8) Disconnect remote control cable from throttle lever.

9) Slowly move throttle lever to full open position while monitoring

voltage reading. Voltage reading should increase and decrease

smoothly.

10) Set volt meter to 20 DC volts. Maximum voltage reading at full

throttle is approximately 7.46 volts.

11) Remove test lead and reconnect TPI harness to EFI harness.

12) Reconnect TAN/BLACK engine head temperature sensor leads

located on port cylinder head.
