EGR Sensor C Circuit

Where it lives

For P044A, the sensor sits on the circuit this code reports. The description of P044A reports a fault at the sensor.

Check these first

• A failed EGR sensor C
• An open or short in the sensor C circuit
• Corrosion at the sensor C connector
• A clogged EGR passage
• An ECM fault on the sensor C channel

What to do next

1. Read the sensor C signal on a scan tool
2. Check the sensor C circuit for an open or short
3. Inspect the sensor C connector for corrosion
4. Check the EGR passages for a restriction
5. Replace sensor C if the signal is out of range
6. Clear the code and retest
