Injection
YES go to 10 NO go to 9
9 - Replace the sensor.
10 - Connect the sensor connector and repeat the resistive check at terminals 18 and 22.
Electric characteristic
18-22 =
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 (>1MΩ), check the continuity of the two lines with disconnected con-
nectors.
Electric characteristic
Grey-white-18 =
0 Ω (continuity)
Light blue/green-22 =
0 Ω (continuity)
