20 distinct codes across 20 real diagnostics on Fiat, including the Fiat-specific ones no generic code list can decode.
Fiat-specific codes
These are manufacturer-specific, which means the same code on another marque is a different fault. That is exactly why they have no page of their own and no entry in any generic code list. Scoped to Fiat and ranked by how often we have actually seen them, they are a claim we can stand behind.
- P1C9B, seen in 3 Fiat diagnostics
- P1498, seen in 2 Fiat diagnostics
- P1641, seen in 2 Fiat diagnostics
- P1325, seen in 1 Fiat diagnostic
