[Diy_efi] Why TWO cam position sensors

[don.broadus at exeloncorp.com]

It Looks like it is for variable valve timing. The G1 sensor is the fixed timing and the G2 sensor will show advance or retard of the camshaft when the ECM signals a valve to port oil to the Advance/ Retard system in the timing gear.

Can someone explain why Toyota use a crank position sensor and also TWO
cam position sensors on the Supra 2JZ-GTE engines? A page detailing this
in the factory manual is at:

Is it for better accuracy than just one cam position sensor, i can't
understand why they use 2. Thanks.
