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?
can try to unhook the negative battery cable wait 15 mins hook back up. And what do you mean by E check?
Without a scan tool there is a "drive cycle", too lengthy to post here, that can be done. Google "OBD II drive cycle". In the meantime keep your gas tank between 3/4 and 1/4. Drive normally for about a week and all the readiness monitors will set. However if your check engine light remains on you still have a problem. HTH. -Jim
Chris, by "E check" cargirl19 is referring to emissions check. -Jim
