1. Check:
TPS input voltage (at idling speed)
Out of specification
Check the CDI
unit.
TPS input voltage (R – O):

±
0.25 V

R
2. Check:
TPS output voltage (at idle speed)
Out of specification
Adjust the TPS
position.
NOTE:
Set the digital tester to the manual range. In
the auto range the voltage changes cannot
be accurately measured.
3. Adjust:
TPS position
Output voltage (P – O):
0.7
±
0.02 V
Checking steps:
Connect the test harness.
Connect the tester leads to the test
harness (P – O).
Start the engine, allow it to warm up
for several minutes.
Measure the voltage at engine idling
speed.
While slowly opening and closing the
throttle valves, check if the voltage
changes gradually.
Adjustment steps:
Start the engine at idling speed.
Move the throttle control lever until it
contacts the fully-closed stopper. Refer
to “Carburetor pickup timing check
