YES go to 10 NO go to 9
9 - Replace the sensor.
10 - Connect the sensor connector and repeat the resistive check at terminals 4 and 22;
Electric characteristic
4-22 =
Resistance equal to the value directly detected at the sensor.
YES go to 13 NO go to 11
11 - If slightly higher values are detected, check the connectors.
If infinite resistance is detected (>1MW), check the continuity between the two lines with disconnected
connectors.
Electric characteristic
Blue-white-4 =
0W (continuity)
Light blue/green-22 =
0 ohm. (Continuity)
