Why are some sensor wires shielded and some aren't? please elaborate on this more

You could shield all sensors if you wanted to - the downsides would be cost of shielded cable, bulkiness of the overall bundle of wires with all that shielding, and the complexity with all the shields to terminate. Given these downsides, usually only the most important and sensitive of sensors are shielded - crank, cam, wheel speed, etc.

-Mark

To elaborate in a nutshell... critical sensors could pick up noise or electrical magnetic interference that could distort the signal giving false feed back to the ecu.

such as cam, crank, knock and wheel speed sensors.

so we ground the shielding to one side only usually at the ecu, so that if they pickup any thing they're drained to ground and give a clean crisp signal.
