How to Replace a Fuel Injector in a Honda CR-V

The Honda CR-V fuel injector uses pressure to mix fuel with air. This method rendered carburetors almost entirely obsolete during the late 1980s and allows the same hardware to be used with different fuels due to the fuel injector's programmable firmware. A fuel injector consists only of a nozzle and a valve; it still requires a pump to inject the fuel into the engine.

Instructions

1

Determine which fuel injector your Honda CR-V will need. This depends not only on the make and model, but also the engine size. Models made from 1996 to 2001 have a 2.0L B20B or B20Z engine and models made after 2001 may be equipped with a 2.0L, 2.2L turbo diesel or 2.4L engine.

2

Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Remove the air intake resonator and electrical connectors for the fuel injectors.

3

Disconnect the hoses for the positive crankcase ventilation (PCV) valve and fuel pressure regulator. Remove the fuel lines and fuel supply manifold with a socket wrench so you can take out the fuel injectors. Discard the old cushion rings and O-rings.

4

Install the fuel injectors to the fuel supply manifold with new cushion rings and O-rings. Use a torque wrench to tighten the nuts on the fuel supply manifold and fuel injectors to 105 inch pounds.

5

Replace the fuel lines and the hoses for the fuel pressure regulator and PCV valve. Install the air intake resonator and the negative battery cable with a socket wrench.

6

Start the engine and check for leaks.
