Vehicle
Citroën Saxo
The 1996-2003 city car, and mechanically the same vehicle as the Peugeot 106 — so 106 information applies throughout and is often easier to find. It sits at the boundary of OBD-II: the earliest cars use PSA's own protocol on a 30-pin connector, and cars from 1998 are EOBD on the standard port, which is the first thing to establish rather than assume. The TU-series engines are simple and durable, and the faults that bring one in are correspondingly basic — the crank sensor and ignition coil pack for a no-start, a throttle-position sensor wearing a flat spot for idle-control codes, and corroded earths behind the battery producing several unrelated readings at once. The VTS's 1.6 16v uses a different management calibration but the same hardware.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
