Fuel Injector 2 - Corrected Flow Rate
Indicates a problem with fuel injector flow rate on cylinder 2.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine control module (ECM) expects a certain amount of fuel to be injected into cylinder 2 based on engine conditions. If the injector lets in too much or too little fuel, the module will trigger this fault code.
What the computer is actually seeing
The ECM monitors the fuel flow through the injector and compares it to the expected flow. If it sees a deviation that falls outside of specific parameters for a set time (usually more than 5 seconds), it sets the code.
What a healthy reading looks like
An acceptable flow rate for a properly functioning injector should be around 5-15 milliliters per minute at idle, depending on engine design and conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the wiring and connectors for injector 2 for any signs of damage or corrosion. Fix any issues found.
- 22. Test the injector's resistance using a multimeter. Expected resistance is typically between 12-16 ohms. If out of spec, replace the injector.
- 33. Perform a fuel pressure test at the fuel rail. Expected pressure is typically 30-50 psi at idle; if low, check the fuel pump and filter.
- 44. Check for any engine vacuum leaks or issues that may affect fuel delivery. Repair as necessary.
- 55. Clear the code and road test the vehicle. If the code returns, consider inspecting the ECM and re-evaluating the injector flow.
Common causes
- Faulty fuel injector
- Clogged fuel filter
- Wiring issue or connector problem
- Low fuel pressure
- Faulty ECM
