Description
Short circuit sensor internally at NOx-
sensor downstream SCR
Open line sensor internally at NOx-sensor
downstream SCR
NOx Sensors are CAN Sensors --> no HW
Pin on the ECU
Short circuit sensor internally at NOx-

NOx Sensors are CAN Sensors --> no HW
Pin on the ECU
Possible Cause
Short circuit sensor internally at NOx-sensor
downstream SCR
Open line sensor internally at NOx-sensor
downstream SCR
Short circuit sensor internally at NOx-sensor
downstream SCR
Action
Threshold for error detection is an internal ECU
threshold.
Check NOx-Sensor downstream SCR catalyst:
water inside? Shake out sensor after
dismounting. => If water inside, replace sen-
sor.
Check mounting position of sensor and judge
it regarding condense water formation /
agglomeration? Rearrange if critical and
possi- ble
Check wiring harness
Exchange sensor
Threshold for error detection is an internal ECU
threshold.
Check NOx-Sensor upstream SCR catalyst:
water inside? Shake out sensor after
dismounting. => If water inside, replace sen-
sor.
Check mounting position of sensor and judge
it
regarding condense water formation /
agglomeration. Check wiring harness
