I disconnect the positive cable instead of the negative because the negative is under the couling could this be why I get that code but it's not all the time
I tow a 2018 edge titanium 3.5 AWD I follow the owners manual and disconnect the battery
Not all the time but most of the time I get a check engine light after towing. When I pull up the the code is is PO68a how do I stop it from recurring
