Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Tundra.

The codes 11 and 21 don't appear as good codes and usually come in a letter/number form, like this P0171. How did you come about these 2 digit codes?

Customer: replied 1 year ago.
Sorry though you would under stand p0011 and p0021
Expert:  Genchi Genbutsu replied 1 year ago.

That's what I thought but just needed to clarify. I take it that these codes were not present before this job was performed, correct?

Do you remember which way you had the arrows face when installing the tbelt? toward or away from the engine?

Customer: replied 1 year ago.
Torward the engine
Expert:  Genchi Genbutsu replied 1 year ago.

I sooo hate to be the bearer of bad news and trust me, when I say that I know you do not want to hear this but the arrows are supposed to face away from the engine. I have included a link to a tech tip about this here.

Doing this job one more time is not what you had in mind but it will fix this issue. You are not the first tech to make this mistake, just keep in mind on Toyota's that the L is always on the drivers side and the R is the passenger.

Does this make sense?

Hello again I reversed the belt and same codes can u tell me where the crank mark goes
Expert:  Genchi Genbutsu replied 1 year ago.

I'm not sure what you're asking. The crank mark where the crank pulley meets the cover or the crank mark on the gear where it meets the front on the engine?

Customer: replied 1 year ago.
Thanks for your help I figured it out the person who did the belt the first time used the T s for lining up the belt not the I marks so I line it up right all good now thank s again
Expert:  Genchi Genbutsu replied 1 year ago.

That's Awesome! Great job on going back in again and fixing what others couldn't. I'm glad that we could get this fixed and hope the pictures helped. When you can, please take the time to rate my help and know that I strive to give Excellent Service.
