What is CID 1074 & How to Solve It?

What is CID 1074:

Cid 1074 points to a problem with the exhaust gas temperature (EGT) sensor circuit. This can lead to improper EGR regeneration or engine overheating.

‍

Why This Happens:

• Faulty EGT sensor.
• Carbon buildup blocking the sensor.
• Damaged or shorted wiring in the circuit.
• Loose or corroded connectors.
• ECM failure to process data.
  
  

How to Fix It:

1. Inspect the EGT sensor and clean any soot buildup.
2. Check wiring and connectors for wear or corrosion.
3. Test the sensor voltage and resistance at different temperatures.
4. Replace the faulty EGT sensor if necessary.
5. Reset the ECM and verify proper exhaust temperature readings.

How to Avoid It Before It Happens:

• Perform regular cleaning of the exhaust system.
• Monitor sensor readings during diagnostics.
• Ensure EGT sensors are free of carbon buildup.
• Clue’s fuel management services track exhaust temperatures and prevent issues with regeneration cycles.
