Reconditioned Ford Fiesta Engine

Petrol or diesel on the Ford Fiesta: which engine is the right match for your failing unit?

The Fiesta spans the period from 2001 to 2017 and is available with six distinct engine options: four petrol units — 1.0 EcoBoost, 1.1 Ti-VCT, 1.25 Ti-VCT and 1.4 Ti-VCT — and two diesels — 1.4 TDCi and 1.5 TDCi. These two families share nothing mechanically, and even within each family, engines cannot be substituted from one variant to another. The engine code stamped on the block is always the essential starting point for any identification.

Petrol engines: three engine families, a wide range of engine codes

The 1.0 EcoBoost is the most widely represented engine, with ten engine codes on record (M1JE, M1JH, SFJC, SFJD, SFJH, SFJK, SFJN, SFJP, YYJA, YYJE). This 3-cylinder unit went through several revisions between 2013 and 2017; two Fiestas from the same year may carry different engines. The 1.25 Ti-VCT covers a longer range (2008–2017) with five codes: SNJA, SNJB, SNJC, SNJD and STJB — the presence of the STJB alongside the SNJX codes signals a series break that must not be overlooked. The 1.4 Ti-VCT comes in four codes (SPJA, SPJB, SPJC, SPJD), and the 1.1 Ti-VCT, a more recent engine, is listed under just one code: XPJB.

Diesel engines: 1.4 TDCi and 1.5 TDCi — two engines not to be confused

The 1.4 TDCi covers four codes (8HR, 8HZ, F6JA, F6JB). The first two references (8HR, 8HZ) are of PSA origin and are structurally distinct from the Ford references F6JA and F6JB: a misread engine code can easily lead to ordering the wrong engine. The 1.5 TDCi is identified by three codes — XVGA, XVGB, XVGC — and shares no components with the 1.4 TDCi despite the similar engine capacity. Failure symptoms vary by family: timing chain seizure, cylinder head cracking and premature bore wear are documented failure points on the diesel engines of this generation, depending on service history.
