P2060Reductant Injection Air Pump Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2060 means the control line of the injection air pump or air valve is held at too low a level: when the output tries to switch it on, the voltage collapses because the wire or the load is connected to ground. Deutz defines exactly this on its EMR L1 controller as P2060-00, a high-side short to ground on output SPN 5796, which drives the air pump or valve. The driver protects itself, so the valve stays closed and atomizing air never reaches the dosing nozzle. Look for wires rubbed through on the frame or the engine block, a water-filled connector or a coil with a short to its housing. An open circuit of the same output is P2059, a short to battery P2061. DEF dosing is blocked until the short is removed.
- What you may notice
- Emission warning lamp on
- DEF dosing blocked
- Possible blown fuse in the air valve supply
- Likely causes
- LikelyControl wire chafed through to ground
- PossibleValve or pump coil shorted to its housing
- RareWater in the connector bridging to ground
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
