Looking for some help on P121b........I know it's the passenger side active exhaust actuator. Either the actuator itself or it's not syncing. I read a TSB on how to troubleshoot. Pressing run and then listen for the actuator to cycle. If cycles more than 30 seconds it needs to be replaced or atleast the spring does
I tried this and cannot hear
I dont want to purchase a replacement if it's another issue. Whatever that my be but....
Does anybody have any other tips
