Hi there,

Most of the time with these you can replace the air injection solenoid to resolve the issue. The 1507 code can be caused by a lot of things, but common issues with this code would be the transmission position switch if the car is a manual. Sometimes the switch gets sticky and the car doesn't realize it's not in neutral. When this happens you will get the 1507 code.
