OK , the car started throwing these codes Fri. P0412 Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1. P0418 Secondary Air Injection (AIR) Pump Relay Control Circuit Bank 1 . I have not had the secondary air connected for several years . Air pump fuse has been pulled for years , The actual connections at the pump ..unconnected @ both locations .
The computer has been tuned with the air pump delete. So I do not understand why it is throwing these codes ..
Looking for input . The SES is driving me nuts

Thx guys

If it's been off for several years, and the AIR codes too - only thing I can think of it's the PCM itself...try resetting it and see what happens. Did you or a dealer just install a new or updated tune?
