P2061 Reductant Injection Air Pump Control Circuit High
Reductant Injection Air Pump Control Circuit High: the control-circuit voltage is above the expected range. This valve doses reductant (DEF/AdBlue) into the exhaust for SCR NOx reduction.
Is it safe to drive with P2061?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyShort to B+
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
Symptoms
- Check engine light or NOx warning on
- AdBlue/DEF level or quality warning
- Possible no-start countdown after ignore period
- Failed emissions inspection (NOx)
