Also known as: 2zz-ge, 2zz, 2zzge, lift-cam 1.8
Toyota's high-revving 1.8 — in the Celica GT-S and Corolla XRS, the Pontiac Vibe GT, and the Lotus Elise and Exige.
Lotus is the reason to know this engine's name. A mid-2000s Elise has a Toyota engine, and its service literature, its parts and its known faults are Toyota's — a fact that surprises owners and that no Lotus document emphasises.
Its defining feature is a lift-cam system that changes camshaft profile at about 6,000 rpm, and the change is dramatic enough that owners describe it as a second engine arriving. That switch is the design working, not a fault.
⚑ When the switch stops happening the cause is almost always oil, because the mechanism is hydraulic: low level, aged oil, or a blocked screen in the lift solenoid all stop it, and the car simply feels flat above 6,000 while running perfectly below. A blocked screen is a cheap part.
Its one serious mechanical weakness is the lift bolts that hold the rocker arms' sliding pins. On hard-used engines a bolt can back out and destroy the head — a known, documented failure with a known fix, and one of the few faults in this catalogue where the community's preventative modification is the standard advice.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
