General information
• Detects the engine speed.
• Controls the ignition timing, fuel injection volume, engine speed, engine
knock, variable camshaft timing, and electronic throttle valve opening
angle.
• Detects the angle of the crankshaft and the position of the pistons.
(Cannot detect the position of the exhaust and compression strokes.)
• Identifies cylinder groups #1 and #4, #2 and #5, and #3 and #6.
• Detects the stroke position.
(Example: TDC of the compression stroke or TDC of the exhaust
stroke.)
• Detects the strokes of the different cylinders using signals of both the
crank position sensor and cam position sensor (PORT EX).
• Control the variable camshaft timing.
Detects the starboard advance angle using variable camshaft timing
control.
Detects the port advance angle using variable camshaft timing control.
Detects the electronic throttle valve opening angle.
Detects the electronic throttle valve opening angle.
Detects the throttle lever opening angle.
Detects the throttle lever opening angle.
Detects the intake air pressure and controls the ignition timing and fuel
injection volume.
Detects the intake air temperature and controls the correction of the
ignition timing.
Controls the correction of the ignition timing and fuel injection volume.
Detects the neutral position.
Detects the engine oil pressure and controls the warning and engine
speed when the engine oil pressure is low.
Sends signals to warn that the engine is overheating and controls the
engine speed when the overheat warning is activated.
Outputs signals to decrease the engine speed to facilitate shifting.
Detects abnormal combustion knock and controls the ignition timing.
