The Toyota ZZ engine family is a straight-4 piston engine series. The ZZ series uses a die-cast aluminium engine block with thin press-fit cast iron cylinder liners, and aluminium DOHC 4-valve cylinder heads. The camshafts are chain-driven. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimised for economy, with torque emphasised in lower revolutions per minute operating range, while the latter is a "square" design optimised for high-RPM torque, yielding higher peak power. The ZZ family replaced the extremely popular cast-iron block 4A engines. Toyota engine names are interpreted as follows. The leading number denotes the generation, and the next one or two letters, specify the engine family. The remaining letters, following a hyphen, describe the engine's major features. For example, the 2ZZ-GE can be decoded as being the second generation of the ZZ engine series and features a performance-oriented cylinder head with widely angled valves (G) and electronic fuel injection (E). 1ZZ 1ZZ-FE The 1ZZ-FE is a version built in Buffalo, West Virginia. Bore X stroke of . Compression ratio is 10.0:1. Output is between at 5,600 rpm with of torque at 4,400 rpm, and at 6,400 rpm with of torque at 4,200 rpm. It uses MPFI, has VVT-i (1998-99 1ZZ engines don't have VVT-i), and features fracture-split forged powder metal connecting rods, one-piece cast camshafts, and either a cast aluminum intake manifold or a molded plastic intake manifold. A factory supported bolt-on supercharger kit was sold for the 2003–2004 Corolla and Matrix by Toyota Racing Development, and Pontiac Vibe by GM Performance. The supercharger gives of boost, with a and of torque increase at the wheels. Its production in Cambridge, Ontario was discontinued in December 2007.

The issue involves the engine control module, and includes the potential for it to develop a crack on the module's circuit board, which can result in the car not starting, the transmission shifting harshly, or the engine stalling. Additionally, Pontiac announced a
