To troubleshoot Cummins fault code 1885, you can follow these steps:
1. Retrieve the fault code: Use an electronic diagnostic tool to read the fault code from the Cummins engine control module (ECM).
2. Interpret the fault code: Consult the Cummins fault code guide or service manual to understand what fault code 1885 indicates. It may provide information about the specific subsystem or component that is causing the issue.
3. Inspect wiring and connectors: Check the wiring harness and connectors related to the component mentioned in the fault code. Look for loose connections, damaged wires, or corrosion. Repair or replace any faulty components.
4. Check sensor operation: If the fault code is related to a sensor, test the sensor's operation using a multimeter or a diagnostic tool. Compare the readings to the specifications provided in the service manual. Replace the sensor if necessary.
5. Verify system voltage: Ensure that the system voltage is within the acceptable range. Low voltage can cause communication errors or false fault codes. Check the battery terminals, connections, and charging system.
6. Clear the fault code: After addressing the potential issues, clear the fault code from the ECM using a diagnostic tool. Monitor the engine operation to see if the fault code returns.
If you are unsure or unable to troubleshoot the fault code on your own, it is recommended to seek assistance from a certified Cummins technician or dealer.

Cummins fault code 1885 indicates an issue with the aftertreatment 1 intake NOx sensor circuit, specifically that the voltage is below normal. Here are some steps to troubleshoot this issue:
1. Inspect the sensor and wiring: Start by checking the condition of the NOx sensor and its wiring harness. Look for any visible damage such as loose connections, frayed wires, or corrosion. Repair or replace any damaged components.
2. Test the sensor: Use a multimeter or a diagnostic tool to test the voltage output of the NOx sensor. Compare the readings to the specifications provided by Cummins. If the sensor is not producing the expected voltage, it may be faulty and needs to be replaced.
3. Check for exhaust leaks: Exhaust leaks can affect the readings of the NOx sensor. Inspect the exhaust system for any leaks or leaks in the area where the sensor is located. Repair any leaks found to ensure accurate readings.
4. Verify exhaust gas temperatures: Low exhaust gas temperatures can cause the NOx sensor voltage to be below normal. Check the exhaust gas temperatures using a diagnostic tool and compare them to the manufacturer's specifications. If the temperatures are too low, it may indicate a problem with the engine or aftertreatment system.
5. Clear the fault code: After addressing the potential issues, clear the fault code from the ECM using a diagnostic tool. Monitor the engine operation to see if the fault code returns. If it does, further diagnostics or assistance from a Cummins technician may be necessary.
It's important to note that these troubleshooting steps are general guidelines. For a more accurate diagnosis and detailed information, it is recommended to consult the Cummins service manual or contact a certified Cummins technician or dealer.
