Code P2444 Cadillac 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 detects that average difference between the predicted system pressure and the actual system pressure is greater than or less than calibrated thresholds for greater than 8 s.
