5. Insert the thin electric conductors 2 (lead)
into the throttle position sensor 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.
