48 more codes

September 26, 2026

Toyota reached 296 codes. Two entries were left out of this batch because no public source supported the meaning, and holding them back beats publishing a guess.

100 more codes and three guides

September 25, 2026

Toyota grew from 148 to 248 codes in two batches, each code traced to a source. Three guides went up: how to read Toyota check engine codes, Toyota OBD-II port locations, and Toyota VVT-i codes explained.

Guide facts checked against sources

September 25, 2026

Every claim in the three guides was checked. Claims that no source supported came out, including the model-specific port hiding spots.

Severity now names the real warning lamp

September 25, 2026

Body and chassis codes used to say Check Engine Light. Airbag faults now say Airbag Light, brake faults say ABS Light, and the rest say body or chassis warning light, which is what you actually see on the dash.

The Toyota site opened and grew to 134 codes

September 6, 2026

Camry, Corolla, RAV4, Tacoma and Lexus coverage started at 30 codes and reached 134 the same day, covering igniters, VVT-i, EVAP, secondary air and transmission codes with strict zero overlap against the generic catalog.
