Internal Control Module Performance Problem
The control module has detected an internal performance issue.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine control module (ECM) is basically the computer for your engine. It does millions of calculations every second to keep everything running smoothly. If it finds something wrong within itself and can't fix it, it triggers this code. Think of it like the computer getting a headache and not being able to make decisions properly.
What the computer is actually seeing
The ECM monitors its own operation and looks for errors in algorithms, calculations, and performance. When it sees values that don't match expected parameters, it sets a P060B code to indicate it can't perform its tasks correctly.
What a healthy reading looks like
The ECM typically should execute tasks with a response time of less than 10 milliseconds. If the response time exceeds this or the inputs don’t match expected output ranges, errors like P060B will occur.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check for any visible damage to the ECM connector and wiring. Look for corrosion, loose connections, or fraying.
- 22. Inspect ground points and power supply connections to the ECM for continuity and proper voltage (should be around 12V).
- 33. Use a scanner to check for additional codes related to the ECM. If other codes are present, diagnose them first.
- 44. Check the ECM software version and reprogram if necessary; make sure it’s updated to the latest version from the manufacturer.
- 55. If all previous checks are fine, consider substituting the ECM with a known good unit to verify if the issue persists.
Common causes
- Faulty ECM
- Corrupted software in ECM
- Short circuit in wiring harness to ECM
- Poor ground connection for ECM
- Power supply issues to ECM

Frequently asked questions
Is it safe to drive with this code?
It's not advisable to drive with this code, as it indicates the ECM may not control engine functions properly, risking a breakdown.
Will this code come back after resetting?
If the underlying issue isn't fixed, the code will likely return after resetting or even during normal operation.
Why does this code appear alongside other codes?
P060B can often appear with other codes because it is a general performance failure code, and other system faults can exacerbate or result from ECM performance issues.
