RepairPal has identified the most common problems with the Toyota as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
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.
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
The ignition coil inside the distributor can fail. There will be a hesitation on acceleration, especially when the vehicle is warming up on cold, rainy days. The pickup coil inside the distributor can also fail and cause a no-start condition. There have also been some failures of the radio noise suppressor inside the distributor, which can short out. Our technicians recommend replacing the whole distributor with a complete, genuine Toyota distributor if any of its components fail.
A problematic center airbag sensor can cause the airbag malfunction light to illuminate.
The fuel gauge may read incorrectly. Our technicians tell us there is a recalibration procedure which should be performed to correct this issue.

Drivers may hear a loud noise, much like a vacuum cleaner, coming from their engine on cold starts. This affects the 2005-2009 Toyota Sequoia iForce 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 Check Engine Light may illuminate with code P0770 and/or P0773 stored. This would indicate a fault with the 3-way lock-up solenoid which could be defective and may need replacement.
The V8 models can experience exhaust manifold failures. A leaking exhaust manifold will sound like an exhaust leak or an audible ticking noise from the engine compartment and will be especially pronounced when the engine is still cold.
