P060B - Internal Control Module A/D Processing Performance
The P060B code indicates that the Engine Control Module (ECM) has detected an internal performance issue with its analog-to-digital (A/D) converter. This converter is responsible for translating analog signals from sensors (e.g., oxygen sensors, throttle position) into digital data for processing. A fault can cause inaccurate sensor readings, leading to drivability problems. This is typically a hardware failure within the ECM itself.
01. Most Common Causes
- Faulty Engine Control Module (ECM)
- Corroded or damaged ECM connectors
- Voltage supply issues to the ECM
- Internal ECM circuit failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine stalling or misfiring
- Poor acceleration or hesitation
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and document freeze frame data.
Step 2: Inspect ECM connectors for corrosion, damage, or loose pins.
Step 3: Check battery voltage and charging system; ensure stable voltage to ECM.
Step 4: Perform ECM software update if available from manufacturer.
Step 5: If all else fails, replace the ECM and reprogram it.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The ECM controls critical engine functions; driving could lead to stalling or loss of power, increasing accident risk.
How much does it cost to fix?▼
Repair costs typically range from $500 to $1500, including parts (ECM) and labor for diagnosis, replacement, and programming.
