Possible Causes
WARNING: This page is about a different variant/trim than selected.
- Purpose of the DTC
- Circuit check of pre selective catalytic reduction NOx sensor
- Electrical Cause
- Yes
- Mechanical Cause
- Yes
- Control Module Cavity
- Circuit reference CAN_L_3
- Circuit reference CAN_3_H
- Monitor Description
- Pre selective catalytic reduction NOx sensor circuit open circuit, high resistance
- Prioritized List of Possible Causes
- The powertrain control module has determined an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output
- Pre selective catalytic reduction NOx sensor circuit open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Pre selective catalytic reduction NOx sensor failure
