With the oil cooler removed you have easy access to both the intake (red arrow) and exhaust (yellow arrow) camshaft magnetic adjusters. The plastic clips can be fragile. Gently lift up the gray clip (red arrow) with a flathead screwdriver and push back on it to release the connection, and then pull straight up.

Why is my air intake inlet flap adjuster not working?

The major problem is the 0.25v. This is an out of range signal and the ECU won’t initialize the whole unit. The ECU will set an error. If we go around somehow solving this corrupted distance and bringing the unit back to a reasonable position, where the initial voltage is not under 0.4v then we are in the race again.

Why are resistors connected to the IAT sensor?

This is, a resistor connected in some way to Intake Air Temperature sensor (IAT), to “fool” the ECM into “thinking” that incoming air is cold, hoping that the ECM will inject more fuel to compensate for the “colder” air. ECMs are programmed to compensate in some way when the air is colder, as colder air carries more oxygen for being denser.
