CAUTION
Measurements refer only to the reference component.
The actual measurement of limited values of resistance requires use of instruments with the SELF-ZEROING function or, if
these are not available, subtract from the read value the short-circuit value of the instrument prods.
Measurements closest to reality are taken including the wiring from the ECU to the sensor.
Always check the continuity of the SHIELD conductor from the sensor to the ECU and the latter’s good insulation from
the other signal conductors.
