P2060
Reductant Injection Air Pump Control Circuit Low
Auxiliary emissions (SCR/diesel exhaust fluid)
Generic OBD-II
Medium
What it means
P2060 means the PCM sees a low-voltage (often short-to-ground) condition in the control circuit for the reductant injection air pump — the pump that supplies air to atomize diesel exhaust fluid in the SCR system. It's usually a wiring, connector, or pump fault. The engine still runs, but diesel emissions systems may respond with a power derate if it isn't repaired.
Medium
Can I keep driving? Driveable at first, but the emissions system may trigger a power derate or countdown — repair before it limits performance.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced engine power or a derate warning (on diesels)
- Reductant/DEF system warning message
Common causes
Most likely first
- Short-to-ground or low-voltage fault in the air pump control wiringLikely
- Faulty reductant injection air pumpCommon
- Corroded or loose connector at the pumpCommon
- Faulty powertrain control module (PCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the air pump control wiring for shorts-to-ground or damage.
- Check the connector for corrosion or a loose fit and clean or repair as needed.
- Test the air pump's operation and current draw; replace the pump if it fails to run or is out of spec.
- Consider the PCM only after the wiring and pump test good.
FAQ
Quick answers
Is it safe to drive with P2060?+
Short-term yes, but diesel emissions systems often respond to reductant-system faults with a power derate or limited-restart countdown. Repair it promptly.
Can I just clear P2060?+
It will return until the low-circuit fault or failed pump is repaired — clearing does not fix the wiring.
