Fuel Injector Driver Circuit Performance Bank 1
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The injector driver stage on bank 1 - the high-side or low-side switching transistor that fires the injectors - reports a performance fault. Typical for a partial driver short, drift in the boost capacitor, or supply ripple under load.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
