Which one is yours
A generic OBD reader gives you the number, not which of these meanings your manufacturer assigned to it. To get to the specific one:
- Use a brand-specific scanner — VCDS for VAG, INPA or ISTA for BMW, XENTRY for Mercedes, Forscan for Ford. It shows the manufacturer's own text rather than the generic one.
- Read all stored codes together — the neighbouring ones usually point at which system is involved and narrow the list.
- Check freeze-frame data: the RPM, temperature and load at the moment it triggered indicate which system was active.
- If you have no brand scanner, tell me the make and model below and I will tell you which of these applies to your car.

Code breakdown
Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The code meanings come from the SAE/ISO definitions and from what each manufacturer documents for the same code, shown by make. The notes on causes and checks are general guidance built from the code family, not a factory test plan for your car.
The same code can mean different things on different makes. Match the meaning to your make before acting on it.
