P2060: Reductant Injection Air Pump Control Circuit Low
What to do
As P2059 — ordinary electrical work with a legal-consequence deadline attached. Do not let the absence of symptoms defer it.
What this code means
The reductant air pump's control circuit reads low — shorted to ground, or open where the resting state reads high.
An electrical diagnosis with P2059's consequence attached: no air, no atomisation, dosing suspended, and the inducement clock running while the car feels perfect. Wiring and connector first, pump last.

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.
