Codes P0340 , P0440.....

[rosier1]

Hi all! My 02 TB with 85k SES light came on the other day. Took it to Autozone and had them read the codes. Came back with P0340, P0440, and C0291. I found it strange these all came up on the same day. Am going to order a new gas cap, new Cam position sensor. Not a big deal and not costly. The brake code has me scratchin my head. Any one else find it strange all these codes came up at the same time? Disconnected the battery to clear em out thinkin it would reset, thought maybe they were old codes? IDK. For the cam position sensor, I read that the cruise control will not work? Mine works! Truck runs fine, no difference in it at all. Any other ideas would be greatly appreciated. I already read all I can here about these codes. Just hoping someone had any thoughts. Thanks!

I'm trying to figure out codes and how they work. Is there a way to know when these codes come up? They are not dated? Are they in some form of numerical order? When they get cleared, do they stay in the memory and come back on the reader? <sigh> I dont wanna take it to the dealer. My wife wants to trade it in, she claims its gettin old! Never had any major issues from it and I love my TB. Trying to convince her we should drop a little maintenance at it and it'll last years more?

I cant find code C0291

the codes get erased, however whatever caused the errors still remains

best of luck

C0291 was an E brake relay I believe. Not to concerned about that one.
Thanks

Put on new gas cap, disconnected battery for a while. No more service engine light. Still gonna throw the cam position sensor in just for fun.

Shoot, 85k is young, should give you many more years without being more expensive than taking on a car payment.
