What P0607 means
P0607 is the general 'module not working correctly' code, used when no specific memory or processor part is named. Ford sets it for wrong instruction execution or too many processor resets in engine and transmission modules; the Ford diesel after five communication errors with its monitoring chip within 20 s (a complete loss of that link is P0600). GM introduced it in the engine module only recently: the 2025 tables evaluate the results of built-in self-tests and error-correction counters, with the lamp in the first trip. Resets can cause brief stumbling or stalling, and some systems switch to limp mode. Software updates fixed it on the Alfa Romeo Giulia 2.9 V6 and Ram 6.7 Cummins, so check bulletins first. The code alone does not say which module set it – the scan tool shows whether it is the engine, transmission, brake or body module.

- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0607
- Check engine light on
- Limp mode or reduced power
- Brief stumbling or stalling (module reset)
- Several implausible codes at once
Common causes of P0607
- Most likelyFaulty module software (update available)
- PossibleInternal module defect (processor, clock, monitoring chip)
- PossibleLow voltage, voltage dips or a poor ground or supply at the module
- Less likelyElectrical interference, e.g. from a faulty alternator or ignition
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0607 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| 07 | The exact fault in that area. |
What to do next
- Note P0607 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0607
What does P0607 mean?
P0607 means "Control Module Performance". P0607 is the general 'module not working correctly' code, used when no specific memory or processor part is named. It is a generic code, so it means the same on every make.
Is it safe to drive with P0607?
Drive gently and only to a workshop. With P0607 the car can go into limp mode (reduced power) to protect itself.
Will P0607 fail an emissions test?
Yes, it can. P0607 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0607 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0607 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
