Code P060B indicates an "Internal Control Module A/D Processing Performance" error. This means the Engine Control Module (ECM) has detected an internal fault while processing analog-to-digital signals from its sensors.
Common causes include:
-
Failed ECM: The internal hardware of the engine computer is malfunctioning.
-
Voltage Fluctuations: Poor battery health, loose ground wires, or a failing alternator causing "dirty" power.
-
Corroded Connections: Water intrusion or corrosion at the ECM connector pins.
Quick Steps: Perform a "hard reset" by disconnecting the battery for 15 minutes. Inspect the battery terminals and chassis ground points for corrosion and ensure they are tight. If the code returns immediately after clearing, check the ECM connector for moisture or bent pins. If everything is clean and tight, the ECM may require professional reprogramming or replacement.
