The P2060: Reductant Injection Air Pump Control Circuit Low refers to a fault where the air pump control circuit is experiencing low voltage. This air pump is responsible for supplying the necessary airflow for the reductant (DEF) injection into the exhaust system to reduce emissions. A low voltage condition in the control circuit can prevent proper operation of the air pump, leading to emission control problems. Common causes include a faulty air pump, wiring issues, or connector problems.
P2060 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2060: Reductant Injection Air Pump Control Circuit Low |
| Is it serious? | Yes, this can prevent the reductant system from functioning properly, leading to higher emissions. |
| Possible causes | – Low voltage in the air pump control circuit – Faulty air pump or wiring – Connector issues |
| How to diagnose? | – Measure voltage in the control circuit – Test the air pump – Check wiring and connectors |
P2060 Meaning
The P2060 code indicates that the reductant injection air pump control circuit is experiencing low voltage, which can prevent the air pump from functioning correctly. This pump is essential for ensuring that the diesel exhaust fluid (DEF) is properly injected into the exhaust stream. If the air pump cannot operate at full capacity due to low voltage, the vehicle’s emissions control system may fail to meet required standards.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related fault codes that could help identify the source of the problem. | OBD-II Scanner |
| Measure Voltage in the Circuit | Use a multimeter to measure the voltage in the air pump control circuit and compare it with the manufacturer’s specifications to confirm low voltage. | Multimeter |
| Test the Air Pump | Use a diagnostic tool to test the air pump and ensure it is functioning within the proper voltage range and delivering sufficient airflow. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connectors | Check the wiring and connectors leading to the air pump for signs of damage, corrosion, or loose connections that may result in low voltage. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After repairs, clear the fault code with an OBD-II scanner and take the vehicle for a test drive to confirm the issue has been resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system after the test drive to ensure that the P2060 code does not return. If the code reappears, further diagnostics may be needed. | OBD-II Scanner |
