What Does P2060 Mean?
The control circuit for the reductant injection air pump (used to atomize DEF spray) is reading lower than expected voltage. This indicates a short to ground, open circuit, or failed pump motor preventing proper DEF injection atomization.
Common Causes
30%
Short to ground in air pump control circuit wiring
28%
Failed DEF injection air pump motor
22%
Corroded or damaged air pump connector
12%
Faulty air pump relay or driver circuit in ECM
8%
Blown fuse or poor power supply to air pump
Diagnostic Steps
1
Step 1: Check fuse and relay for reductant air pump circuit; verify power at pump connector
2
Step 2: Disconnect air pump connector and measure resistance of pump motor to ground
3
Step 3: Check for short to ground on control wire between ECM and air pump with pump disconnected
4
Step 4: Command air pump on with scan tool and monitor voltage/current draw to identify pump operation
5
Step 5: Replace air pump if circuit tests normal but pump fails to operate or draws excessive current
Estimated Repair Cost
$250 - $800
Parts + labor, varies by vehicle and location
The control circuit for the reductant injection air pump (used to atomize DEF spray) is reading lower than expected voltage. This indicates a short to ground, open circuit, or failed pump motor preventing proper DEF injection atomization.
The most common cause of P2060 (Reductant Injection Air Pump Control Circuit Low) is: Short to ground in air pump control circuit wiring
Typical repair costs for P2060 range from $250 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle remains safe to drive but DEF injection may be ineffective. Continued operation will result in increased emissions and potential vehicle performance limitations.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2060 to identify the root cause.
