The 2015 Honda Fit uses a 1.5-liter inline-4 engine with port fuel injection and has four fuel injectors—one for each cylinder.
In more detail, the Fit's 1.5L i-VTEC engine (commonly identified by the L15B designation) employs sequential port fuel injection. Each of the four cylinders has its own injector mounted on the intake port, delivering fuel in a timed sequence controlled by the engine control unit. This four-injector setup is standard for this generation and helps balance efficiency with responsive performance.
Injector count and configuration
The four-cylinder layout means there are four individual fuel injectors in the system, matching the number of engine cylinders. This configuration is typical for Honda’s non-turbo, gasoline-powered Fits of this era and supports precise fuel delivery through the port fuel injection system.
Technical context
The L15B engine in the 2015 Fit uses sequential port fuel injection (PFI) as part of Honda’s PGM-FI system. Injectors are fired in a sequence that corresponds to each cylinder’s intake event, and the system operates without direct injection in this model year.
Maintenance considerations
injector health can influence idle stability, fuel economy, and throttle response. If you notice misfires, rough idling, or reduced efficiency, one or more injectors may require inspection, cleaning, or testing their electrical resistance. Regular maintenance according to Honda’s service schedule supports consistent fuel delivery across all cylinders.
Summary
The 2015 Honda Fit has four fuel injectors—one for each of its four cylinders—forming a four-injector port fuel injection system integral to its 1.5-liter i-VTEC engine.
