P2058: Reductant Injection Valve Circuit High Bank 2 Unit 2
What to do
Inducement deadline applies. Ask for the winding to be measured, and for the shared loom to be checked if other injectors are reported at the same time.
What this code means
The bank 2 unit 2 injector circuit reads above its valid range — an open circuit or a short to supply. Measuring the winding separates the injector from its harness, and on the longest run of underbody wiring in the system the harness is the more likely.
Likely causes
Start here
- Open circuit in injector wiring · moderate
- Road damage to underfloor wiring · moderate
- Corroded or loose connector · easy
Less common
- Faulty reductant injector · specialist

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
