DTC P229E-13: NOx Sensor Circuit (Bank 1 Sensor 2) - Circuit open: Action
- Vehicle Conditions to enable DTC Logging Strategy
- NOx sensor released, the dew point detection function is initiated (after engine start there is a strategy to avoid activation if water is present in the exhaust, the function integrates the warmth quantity seen by the sensor and then releases it, then the sensor is heated and starts measuring)
- Prioritized Checks to Perform
- Refer to the appropriate SYSTEM WIRING DIAGRAMS information and check the post selective catalytic reduction NOx sensor circuit for open circuit, high resistance
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Check and install a new post selective catalytic reduction NOx sensor as required
- Using the Jaguar Land Rover Approved Diagnostic Equipment, clear the DTCs and retest
