2003 Toyota Corolla Engine

The 2003 Toyota Corolla engine listed here is the 1ZZ-FE. This page identifies the engine code for the model year; it does not provide a horsepower, torque, displacement, fuel-economy, or other engine rating. If you need a figure that is not listed here, confirm it on the door jamb or in the owner's manual.

Use the engine code to distinguish the listed engine from other engines, rather than assuming every Corolla year or trim has the same specification. The available fact for this page names the 1ZZ-FE but does not specify differences among trims, equipment levels, or configurations. It also does not give a comparison with engines used in other years, so check the applicable year and vehicle documentation before relying on a specification.

The catalog entry is limited to the engine identification shown for this model year. For details beyond that identification, including any ratings or configuration-specific information, consult the owner's manual or the door-jamb label.
