ADJUSTMENT
1. Disconnect TPS from EFI harness (1).
1
2. Connect digital using TPS Test Lead Assembly
(1) (P/N 91-816085) between TPS connector (2)
and EFI harness connector (3). Set voltmeter to
2 DC volts.
IMPORTANT: TAN/BLACK head temperature
leads must be disconnected from port cylinder
head before adjusting TPS.
3. Disconnect TAN/BLACK engine head temperature
sensor leads located on port cylinder head.
4. Turn key to the ON position.
5. Loosen screws (1) securing TPS to manifold.

6. Rotate TPS fully clockwise (holding throttle shaft
in closed position). On models with ECM P/N
14623A15 and above, voltmeter should read
.200 - .300
. If readout is not within specifications,
adjust TPS to obtain readout of .240 - .260.
NOTE:
If engine appears to run too rich or too lean,
TPS can be readjusted. Decreasing voltage yields
leaner mixture. Increasing voltage yields richer mixture.
Allowable TPS range: .200 - .300 volts.
7. Tighten TPS screws 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 TPS harness to
EFI harness.
NOTE:
The Digital Diagnostic Terminal (DDT) can be
used to determine whether the TPS is set within the
recommended operating range of 0.200 0.300
volts. However, it is recommended that the DDT not
be used to make adjustments of the TPS. Due to the
circuitry characteristics of the ECM, the DDT is not
able to always display accurately small TPS
movements. A digital voltmeter should be used when
making adjustments to the TPS.
