P1415 Secondary Air Injection (AIR) Pump Current Sensor - Circuit Low
What does P1415 mean on a Honda?
P1415 — Secondary Air Injection (AIR) Pump Current Sensor - Circuit Low. This Honda-enhanced code applies to S2000.
Common causes of P1415
- Failed air pump drawing no current
- Open in the pump current sensor circuit
- Blown AIR pump fuse or failed pump relay
- Seized air pump motor from moisture ingress
- Faulty current sensor or ECM sensing circuit
How to fix P1415
- Listen for the air pump running on a cold start
- Check the AIR pump fuse and relay before testing further
- Measure pump current draw against spec during commanded operation
- Inspect current sensor wiring for opens and corrosion
- Replace the air pump or current sensor as testing indicates, then verify on a cold start
