2006 Toyota 4RUNNER: check engine light

Filed Apr 16, 2015 · Driver assistance, Engine · 118,000 miles · CT

Traction control light came on, check engine light came on and vehicle would move only slowly. Turned car off and on several times, tried engaging 4 wheel drive and other drive functions, tried accelerating, but vehicle would only move slowly. After turning off and on one more time the vehicle drove as normal but all the warning lights stayed on. This happened in a parking lot while going slowly. Mechanic has indicated that this resulted from a failure of the air injection pump and air valve, which apparently for some reason turns off traction control. This is a common enough problem on tundras and sequoias that there is an "extended warranty" offered on these vehicles. I do not know if the air injection pump and air valves on 4 runners are the same design or same model, but there are numerous complaints on the internet of the same problem for 4 runners as for tundras.

The secondary air induction pump (aip) and switching valves failed on my 2006 4runner limited with v8. This is the same issue that is seen on toyota sequoias and tundras. Toyota has issued a special extended warranty for this system on those vehicles, but not on the 4 runners, even though the defective systems / parts are the same. Toyota customer case # 1409160408. This is a > $2000 repair to basically clear the check engine code and allow me to pass state inspection. I believe there should be a recall on this system or at least have toyota cover all vehicles with this defective system, not just certain higher-volume model years.

Cel vscoff vsc trac. Had it checked, was told #6 cylinder plug or coil, replaced coil and all spark plugs .cel light went off the next day but came back on following day. Noticed a sound of water moving in a pipe or what sounded like in a pipe behind dash for a second or so. Was idling and running rough while driving, engine was shaking. Went on some web sites read some comments from other owners ,bad head gasket. 4runner has been well taken care of never abused only 8 years old, normal miles I think, not very happy with this. Bad design of cylinder head. I own a 94 4by 4 pick up bought new 250,000 miles lot a original parts still on truck runs very well except for bad rot on chassis happy with truck was very good to me as was I to it. I also have a 01 tundra sr5 bought 2 years ago with 132,000 runs well, 02 sensor replaced pass. Front went well but now have to replace pass. Rear impossible since rot will not permit me to have to replace cat converter, noticed lots of rot on frame as well as other areas under truck. Have loved toyotas till now only had good things to say about them, starting to have second thoughts.

I brought my car in for regular service and new brake pads and rotors. I was told one of the brake calipers on the front wheels was frozen. If the brake caliper is frozen, then the car has significantly reduced stopping power. There was no engine light indicating the problem. Multiple people have complained about calipers on the 4 runner. Please conduct an investigation and seek a response from toyota.

2006 toyota 4runner check engine light disables traction control and vehicle stability control when on. For instance the car needed a gas cap. So the check engine light came on as well as the traction control and vsc light. Icy conditions and having something such as this fail because of poor wiring could be very dangerous.

Our 2006 toyota 4runner with a v8 engine has lost accelerator response on two occasions in the first year we have owned it. The check engine, vsc and trac lights all came on and the vehicle would not respond to accelerator inputs. The first occurrence was july 2006 when the vehicle had approximately 3800 miles on it. The throttle control module was changed and the problem seemed to be fixed until it happened again in february 2007 when the vehicle had approximately 9800 miles. The vehicle was in the shop from february until august 2007. Toyota replaced the throttle control module again, then the accelerator pedal and the engine control computer, all of which did not fix the vehicle. They finally replaced the entire wire harness in august 2007 which has the vehicle working again. We have asked toyota to re-purchase the vehicle from us because we are concerned about the safety and reliability of this vehicle. If this loss of power were to happen again while on the highway it could cause a serious accident! Toyota has refused to re-purchase or replace the vehicle. Please look into this problem so that other toyota 4 runner owners and future owners are aware of this potential safety problem with these vehicles.
