Checking The Crankshaft Position Sensor; Checking The Lean Angle Sensor - Yamaha 2014 MT-07 Service Manual

2. Ignition coil
c. Turn the main switch to "ON".
d. Measure the ignition spark gap "a".
e. Crank the engine by pushing the " " side of
the start/engine stop switch and gradually in-
crease the spark gap until a misfire occurs.

CHECKING THE CRANKSHAFT POSITION
SENSOR
1. Disconnect:
• Crankshaft position sensor coupler
(from the wire harness)
2. Check:
• Crankshaft position sensor resistance
Out of specification → Replace the crank-
shaft position sensor.
