6. Adjust:
•Idle speed
Refer to “IDLE SPEED ADJUSTMENT”
section in the CHAPTER 3.
7. Insert the thin electric conductors 2 (lead)
into the TPS coupler 1, as shown, and
connect the tester to them.
CAUTION:
Do not insert the electric conductors
more than required because it may
reduce the waterproof function of the
coupler.
Make sure that a short-circuit does not
develop between the terminals because it
may cause damage to electrical compo-
nents.
8. Start the engine.
9. Adjust:
•TPS output voltage Tester (+) lead
→ Yellow lead

Tester (–) lead
→ Black lead

Adjustment steps:
Adjust the installation angle of the TPS 1 to
obtain the specified output voltage.
NOTE:
Measure the output voltage accurately with
a digital electronic voltmeter that gives an
easy reading of a small voltage.
