P060C - Internal Control Module Main Processor Performance
The P060C code indicates that the Engine Control Module (ECM) has detected an internal performance issue with its main processor. This can be caused by internal circuit failures, voltage irregularities, or software corruption. The ECM is responsible for critical engine management functions, so this fault can lead to drivability problems and potential engine damage if ignored.
01. Most Common Causes
- Faulty ECM internal processor
- Low battery voltage or poor electrical connections
- Corrupted ECM software or firmware
- Short circuit or open circuit in ECM power/ground
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine stalling or rough running
- Reduced engine power or limp mode
- Poor fuel economy and hesitation
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and document freeze frame data.
Step 2: Check battery voltage and charging system; ensure voltage is stable (12.6V+ engine off, 13.5-14.5V running).
Step 3: Inspect ECM connectors for corrosion, bent pins, or loose connections; clean and tighten as needed.
Step 4: Perform a battery draw test to rule out parasitic drain affecting ECM.
Step 5: If all else fails, reprogram or replace the ECM following manufacturer procedures.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not recommended. The ECM controls critical engine functions, and driving could cause stalling, reduced power, or further damage. Have the vehicle diagnosed and repaired promptly.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. If ECM replacement is needed, parts and labor can range from $500 to $1,500 or more depending on the vehicle.
