Two problems related to other fuel system fuel injection system have been reported for the 2005 Toyota 4Runner. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2005 Toyota 4Runner based on all problems reported for the 2005 4Runner.
The secondary air injection pump is sending error messages and the vehicle is now in limp mode. The vehicle will not go over 30mph.
My check engine light came on along with vsc trac. After taking vehicle to dealership I was told that the repair would cost $2,048. 73 due to the air pump being stuck in off position. While Toyota in response to reports of air induction pump assemblies and/or air injection switching valves issues on their 2007-2010 tundra and 2008-2010 sequoia models, Toyota has decided to increase its warranty on these parts and is even offering a reimbursement if you already had this issue fixed. My vehicle has the identical engine of the above-named vehicles but Toyota does not offer any help with the 4runner. It is my understanding that if I do not get the problem fixed it becomes a huge problem within federally mandated emissions requirement.
