I started up the truck this evening and suddenly the engine light came on, transmission light on, trac light on, and the hi and lo 4x4 lights are blinking and the vsc light is blinking.....???!???!
drives fine, temp fine, rpm/speed ratio seams fine. Whats wrong, where do I start for trouble shooting, what gadgets do I need? Thanks.

First problem since new....

 

when you say engine light do you mean check engine light?
How many miles? 10 years old you may have hit a preset warning for something like a timing belt or....
first step is to take it to an automotive parts store and have the codes read.
or get a code reader yourself and pull the codes, than google them.

 

Yeah that was the plan. 85,000mi. Seams alittle dramatic for a preset. Yea the check engine light..... and almost EVERY other light as well....

 

i'd call the dealer
i think the timing belt is supposed to be changed at 7 years or 90k'ish

what codes showed up when you had them pulled?

 

Sorry, finally had time to pull the codes:

electrical and emissions are my weak areas. This gonna be in the haynes?

 

Ok ready to order air check valves for 2007 4.7 tundra, but the 2006 shows two, the 5.7 show two, but the 4.7 shows just one? Anyone kniw if the others have a specific right/left and the 4.7 just has one or dies it mean the one can be used for the right or left but still requires two? OR does the 2007 4.7 really only need one?
