Control Module Performance
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The ECM performs an internal self-test and detects a processor or memory performance fault that does not fit the more specific P0601 to P0606 codes.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

|---|---|---|---|
| 1 | ECM internal performance fault | Very common | — |
