2006 Toyota 4Runner ProblemsAutomatic Transmission May Not Shift Correctly at High Mileages
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
Drivers may hear a loud noise, much like a vacuum cleaner, coming from their engine on cold starts. This affects the 2005-2009 Toyota 4Runner V8 models.
The noise is from the secondary air pump, which sends hot air to the catalytic converter when the engine is cold. This allows the catalytic converter to clean exhaust better, and lower emissions while the engine is warming up.
Pump failure may result in:
- Check engine light
- OBD trouble code P1445
- Smog test failure
Fixing the issue involves removal of the intake manifold, and replacement of the secondary air pump.
The Toyota 4Runner may develop a condition with the HVAC ducting system causing noisy and faulty operation of the blend doors. The blend doors are actuated by the selector button, and change the direction of airflow to the selected location, i.e. vent, floor, defrost.
The correction is to replace the blend doors.

The accelerator pedal can become trapped under an unsecured or incompatible floor mat. This can cause the accelerator pedal to stick in the wide open position, increasing the risk of a crash. At this time, the remedy plan is still under development, but will most likely involve modification or replacement of the accelerator pedal and Toyota all-weather floor mats. No schedule of owner notification is available at this time. The Toyota recall number is 90L; the Lexus number is 90LG.
