P060B

Internal Control Module A/D Processing Performance

Q: Is it safe to drive with P060B?

Not for long. This flags an internal fault in the engine computer's processing, which can trigger limp mode or stalling and make sensor data unreliable. Have it diagnosed before extended driving.

Q: Can I just clear P060B?

You can try, but internal-module codes usually return quickly. If it comes right back after clearing, the module or its power/ground supply needs attention.

ECM/PCM internal Generic OBD-II High

What it means

P060B means the engine control module has detected an internal fault in its own analog-to-digital (A/D) processing — the part that converts sensor voltages into digital values it can use. Because the computer can no longer fully trust its own readings, it may enter limp mode or run erratically. Confirm power, grounds, and software before condemning the module.

High

Can I keep driving? Limit driving — an internal computer fault can put the engine into limp mode or cause stalling, and sensor readings may be unreliable until it's diagnosed.

How to diagnose & fix

Work through it in order

Read all stored codes and freeze-frame data; this is an internal-module code, so start by ruling out external causes.
Inspect and clean the ECM power and ground connections — poor grounds are a common trigger for internal-processing faults.
Check the ECM connectors for corrosion, water intrusion, or bent pins.
Check for a manufacturer software update/reflash for the ECM.
If the fault persists with good power, grounds, and software, the ECM likely needs replacement and programming.
