| Diagnostic code p0121 - throttle body it is a common issue among all denali owners and is covered under warranty. but if this issue is known by the manufacturer this should be a recall as this could cause an accident. solution is to replace the throttle body (which are currently on back order) dealers will charge between $95 & $110 to diagnose the problem and determine if it is covered under warranty. owners should be weary of dealers trying to charge for this fix. especially of the denali is under 100k miles. *tr | |||
