Crankshaft Position (CKP) Sensor
The crankshaft position sensor is an
inductive pulse generator which scans 36-1 cast protrusions on the flywheel. Minus one means that one of the cast protrusions is missing and this gap is located at 90° before top dead centre. This gap is used by the powertrain control module as a reference for crankshaft position. The crankshaft position sensor sends an alternating voltage signal to the powertrain control module where it is converted and becomes the digital, profile ignition pick-up (PIP) signal.
Answer:- Inductive?
Idle Air Control (IAC) Valve
The idle air control valve is an electronically controlled solenoid valve which allows a flow of air to bypass the throttle plate. Engine speed can, therefore, be maintained irrespective of engine load. The idle air control valve is controlled by
grounding pulses from the powertrain control module, the length of which determines the position of the valve.
Answer:- Pulse?
The two quotes above were copied from
HERE FOR EXAMPLE but are also referenced later on with different measuring methods which is likely for different engine. All say the same relevant answer to the question you asked - I think :lol:
Fuel Injectors
The fuel injectors are activated sequentially by the powertrain control module which modifies fuelling by adjusting fuel injector opening times according to engine operating conditions.

Answer:- ??? - there may be info somewhere in that site manual but it's huge, so I could of missed it easily & couldn't find an efficient search.
The same goes for the
VCT solenoid - it is referenced many times but couldn't find any specs or descriptions like the ones above.
k:
I take no resposibility for any of this information - I just read this sh!t (for over an hour because I was bored) & then pasted it in here :lol:
