P1441 is one of the most common causes of Limp Mode on certain Toyota vehicles with a secondary air injections system failure. The most common cause is a failing air induction pump that can no longer create enough pressure to prevent the exhaust from flowing backwards into the air valves. They can also become stuck from carbon or corrosion much like an EGR valve. The problem can easily be taken care of while saving thousands of dollars in repair costs by installing an Original Secondary Air Injection System Bypass Kit from www.hewitt-tech.com
