Question On 1G-Fe Camshafts

[LexIS200Sport]

Hey peeps, apologies for the very basic question...

As far as I'm aware, the IS200 has a twin-cam (DOHC) engine, as mention here and several other sources.

However, I was looking at the cambelt replacement walk-through and noticed that there was only a single sprocket for the camshaft?

I'm new to Toyota engines, but I clearly remember that my Nissan RB20DET motor, which is also a 2-litre DOHC inline-6 unit, has two cambelt sprockets for its twin-camshafts, instead of one.

Could anyone explain to me how does this work in our engines?

The sproket is atatched to one of the camshafts. the camshafts should be linked togheter with a gear making them spinn relative to each other. and thus with the crank throught that one sproket and gear.

An extremely old post but yes, the two cams are mechanically meshed together with the belt driving the exhaust cam.
