Code P2435 Chevrolet Description
Ignition voltage is supplied to the secondary air injection pump and air injection shutoff/check valve relays. The ECM controls the relays by grounding the control circuits, which activates the relays. When the relay contacts close, voltage is supplied to the pump and the valves, which turns the pump on and opens the valves.
The Diagnostic Trouble Code (DTC) will set when the ECM determines that the pressure sensor value change at either shutoff/check valve and the signal variation are not to factory specification when the air injection pump is commanded ON.

- Faulty Secondary Air Injection Pump Relay
- Faulty Secondary Air Injection Pump
- Secondary Air Injection Pump harness is open or shorted
- Secondary Air Injection Pump circuit poor electrical connection
