Where it lives

For P2060, the circuit described runs through the pump. The description of P2060 reports a fault at the pump.

Check these first

• A reductant injection air pump control circuit with a low signal
• A short to ground in the injection air pump control circuit
• A failed reductant injection air pump
• An open or short in the injection air pump harness

What to do next

1. Command the reductant injection air pump with a scan tool
2. Look for a short to ground in the injection air pump control circuit
3. Inspect the injection air pump connector and wiring
4. Test the injection air pump control circuit for open and short faults
5. Replace the reductant injection air pump if the low signal returns
