ECU 004360.07 – SCR Inlet Temperature Fault. John Deere System Advisory.
ECU 004360.07 (ECU 4360.07)
Code: 004360.07
Shortcode: 4360.07
Description:
This diagnostic trouble code is set when the Selective Catalytic Reduction (SCR) temperature module detects a problem with measuring the inlet temperature. Accurate temperature measurement is crucial for the proper functioning of the SCR system, which reduces nitrogen oxide (NOx) emissions.
Reaction:
The ECU may adjust or limit the operation of the SCR system to prevent potential damage, which can impact the efficiency of NOx reduction and overall emissions compliance.
Recommendations:
- Inspect Temperature Sensor: Check the SCR inlet temperature sensor for proper operation. Replace the sensor if it is faulty.
- Inspect Wiring and Connections: Look for damaged, frayed, or loose wiring and connectors associated with the SCR inlet temperature sensor. Repair or replace as necessary.
- Check for Contaminants: Ensure that the sensor and its surroundings are free from contaminants that could affect the temperature readings.
- Test Sensor Circuit: Use diagnostic tools to test the sensor circuit for continuity and correct voltage levels.
- Reset ECU and Monitor System: After addressing the issue, reset the ECU to clear the fault code and monitor the system to ensure accurate temperature measurement.
Note:
Accurate temperature readings at the SCR inlet are essential for effective NOx reduction and maintaining emissions compliance. Regular inspections and timely maintenance can help prevent temperature sensor-related issues.
