About this catalog

OBD2 PID Knowledge is a free, English-language reference for OBD-II and UDS signals on European hybrid (HEV) and plug-in hybrid (PHEV) cars. One curator reviews sources and publishes every catalog row. Visitors cannot edit the catalog; they can submit a tip or mark a page helpful, unclear, or wrong.

The domain name

This catalog is served at obd2pid.com. It is not a log viewer, charting tool, or trip-file analyser. There is no CSV upload. The catalog explains PIDs, adapters, logging apps, and vehicle platforms so you can interpret data you already collect elsewhere.

Related product

Trip CSV analysis lives on a separate site: OBD2Lab (obd2lab.com) — local-first viewer; your log files stay on your device. This knowledge catalog does not sell software and does not open trip files.

How publishing works

Official standards (SAE J1979, ISO 14229, and related documents) outrank community notes and app exports. Tips stay pending until they are checked. See sources and confidence.
