DTC Lookup explains OBD-II diagnostic trouble codes such as P0301 or U0100. It returns the code's system and standard title, which warning light it turns on, and on paid plans the full description, likely causes ranked by likelihood, symptoms, repair difficulty, estimated cost and labor hours, and related codes. Carmaker-specific codes are covered for 32 makes.
It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 1 credit per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.
A real example — the input you type, and the values you can pull from it. Click any cell to see the formula behind it.
Fill =VERVE("dtclookup", "P0301", "field", "found") down a column and DTC Lookup returns a result for every row — a batch of live values in a single drag, no code.
Add DTC Lookup beside a table you already have to append its output right where your data lives, then sort, filter, or chart on it.
Set the sheet to refresh on a schedule and the dtc lookup values keep themselves current without anyone re-typing.
The same function works in both apps — install once, sign in with your key, and type it into any cell.
Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.
=VERVE("dtclookup", "P0301", "field", "found")Same source, same arguments, same key — in Excel on desktop, the web, or mobile. Excel namespaces it as VERVE.CALL. Drag to fill a whole column.
=VERVE.CALL("dtclookup", "P0301", "field", "found")Tune the result by adding name=value before the field argument — in any order. Leave one out and its default applies.
The vehicle make, for carmaker-specific codes, for example Ford, Chevrolet or Volkswagen
=VERVE("dtclookup", "P0301", "make", "Ford")Language of the title, description, causes and symptoms of generic codes
=VERVE("dtclookup", "P0301", "lang", "en")Add a field name as the last argument to land just that value in the cell.

On the Free plan a marked field is withheld and a marked input is ignored — either way the cell reads #PREMIUM(name) instead of a value, so a gated answer can never be mistaken for a real one.
