causes for code 552

The KOEO self-test is an electrical test only. So either you are not getting the right voltage back to the computer or you have a power supply or ground problem or a computer problem or a wiring problem in that circuit.
TROUBLE CODES (DTCS) 553 AND 552: CHECK VOLTAGE OF VPWR CIRCUIT.
DTCs 553 and 552 indicate that voltage output for Secondary Air Injection solenoid(s) did not change when activated.
Possible causes:
-- AIRB/AIRD circuits shorted to power.
-- AIRB/AIRD circuits open or grounded.
-- AIRB/AIRD resistance out of range.
-- Damaged Powertrain Control Module (PCM).
