How to reset computer on a 2009 impala after service of New battery and replaced gas purge solenoid and air injection solenoid replaced?
The service engine light came on. Went to Auto zone and the codes came up gas purge canister code and I had it repaired. The light did not go off. New code reading was secondary air injection code. The Air injection solenoid was replaced. The service engine light went off. After 4 days of driving the car the computer has not reset and I can not get my E check done. How do you reset the computer?
