Hi, this is Mario and I will help you today.I am attaching a step by step diagnostic procedure for this code. A common cause is a defective AIR (Air Injection Reaction) control valve. Also, there is a service bulletin on a software update that addresses this code.If it has not been done already, I would recommend having this update done before replacing any parts. If this information is helpful, please provide a positive rating, as this is the only way I am compensated for my service. Thank You.
