Please help me.
I have 1.6L CVH EFI intercooled Turbo in my Westfield.
I am changing to steel flywheel.
The car has a sensor in the engine block on left hand side which picks up something on the flywheel.
What is the purpose of the sensor ? What signal is sending ?
My old flywheel had a line scribed, I thought TDC.
The new steel flywheel does not.
Can I use this new flywheel ?.

Thank you for your help.
