P060A: Internal Control Module Monitoring Processor Performance

What it means

The control module detected a performance problem in its monitoring processor. The code alone does not specify the processor fault or the vehicle's fallback behavior.

At a glance

• Usually lights the check-engine light

How it works

The control module uses a monitoring processor to check whether its own internal operations are performing correctly. P060A sets when that processor's performance check fails; the code does not specify the failed task or how the vehicle will respond.

Common causes

Most likely first.

1. Monitor processor internal fault
2. Module software outdated, reflash may resolve
3. Supply voltage outside specification

Symptoms

• Check engine light on
• Possible limp mode or no-start
• Multiple follow-up faults across modules
• Reset/relearn may be needed after repair

How to diagnose it

1. Capture freeze-frame data and scan all modules for related faults, especially low-voltage or communication problems.
2. Check battery and charging-system condition and inspect module power and ground connections for corrosion or looseness.
3. Inspect module connectors and harnesses for damaged wiring, moisture, or poor terminal contact.
4. Check the manufacturer's service information for applicable control-module software updates.
5. If the fault returns with stable power and correct software, test module circuits to specification and evaluate the monitoring processor for an internal fault.

Common fixes

• Repair poor module power, ground, or connector connections.
• Correct battery or charging-system problems that cause unstable voltage.
• Reprogram the module if an applicable update is specified.
• Replace and configure the module if the monitoring-processor fault is confirmed.

Can I keep driving?

If the vehicle behaves normally, keep driving limited and avoid trips where limp mode or a no-start would create a hazard. Stop if power becomes restricted, the engine stalls, or it runs erratically.
