About the Sequoia

The Sequoia is a Full Sized sports utility vehicle created by the Japanese car company Toyota.

Referred to as the XK30/XK40, the first models were launched in the year 2000 after several years of design work.

After the styling patent was filed, Toyota displayed the production model at the North American International Auto Show and was available with two 2.4-liter gasoline engines that could be coupled with either a 4 or 5-speed automatic transmission.

Toyota gave the Sequoia a new facelift in 2005 which included a new engine and a 5-speed automatic transmission with a towing capacity of 2,812 kg – 2,948 kg.

Engine options increased for the second generation along with the power output and these newly styled models were displayed at the Los Angeles Auto Show, November 2007.

Following crash tests undertaken by the National Highway Traffic Safety Administration, the Sequoia achieved a full five stars for the frontal driver and four stars for the frontal passenger.

Unfortunately, Toyota issued a recall for 2009 – 2010 models, there was evidence of unwanted friction on the accelerator pedal and so customers were advised to take their vehicles to have a small trim fitted to alleviate the problem.

The latest models are now constructed upon the TNGA-F (GA-F) platform along with the Toyota Land Cruiser, Lexus LX and the Toyota Tundra.

The Toyota Sequoia can sometimes show the following error codes:

  • P0420 – Poor performance from the catalyst system.
  • P0430 – This fault code shows that the catalytic converter Is not behaving efficiently.
  • P0455 – There is a leak in the EVAP system and it cannot maintain the required pressure.
  • P0157 – A low voltage originating from the oxygen sensor circuit.
  • P0031 – A heating element has low voltage.
