Poor results of OHM measurements of devices under bonnet

[djArias]

I've read the mx-3 online manual and I found there that one should measure the resistance of devices under bonnet to make sure that they work fine, I did that and my results are poor:
Intake air temperature sensor - should be around 2,21-2,69 I have 2,9
Resistance of high-tension lead - should be 16 kohm I have around 3kohm
Idle air controll valve - should be 10,7-12,3 ohm I have 12,7 ohm
Heated oxygen sensor - should be 6 I have 8...
Does this mean that I have to replace all the above mentioned?

Intake air can be a little higher or lower depending on ambient air temp, its fine.

The high-tention leads are also known more commonly as plug wires and the lower the better resistance.
16K ohms is a max and anything over means replace them. 3k ohms means they are fantastic and need not
be replaced.

Idle air control valve resistance is fine at 12.7 ohms.

and your 02 sensor is dandy at 8 ohms.

Your components check out fine.
