Invalid Data Received From Image Processing Sensor L

Where it lives

For U0571, the part to look at first is the sensor named here.

Check these first

• A blocked or dirty lens on image processing sensor L
• Stale calibration or an outdated software load in the image processing sensor L
• Electrical noise on the data bus corrupting the image processing sensor L signal
• A low battery or charging fault that browns out the image processing sensor L

What to do next

1. Scan all modules and record the stored and pending network codes
2. Check the image processing sensor L data bus wiring for opens, shorts, and chafing
3. Confirm the image processing sensor L reports correct live data on the scan tool
4. Repair or replace the image processing sensor L if the circuit, power, and bus tests pass
5. Clear the code and retest to confirm the image processing sensor L fault is gone
