Diagnose soon
Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Fuel Injector Group E Supply Voltage Circuit/Open
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 supply rail to injector group E is open, so none of the injectors in this group can fire. The affected cylinders produce no power and the engine runs rough or on reduced cylinders. Causes: a broken supply wire, an open relay or fuse, or a disconnected group-E supply connector.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

Many vehicles show no symptom at all beyond the warning light. The absence of a symptom does not mean the fault is not real.
| # | Cause | How often | Component |
|---|---|---|---|
| 1 | Open supply wire or blown fuse | Very common | — |
| 2 | Pin pushed back out of connector body | Occasional | — |
| 3 | Cracked solder joint inside the module or sensor | Occasional | — |
Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
