What is Body Integrated Unit?

No it's not , the TIPM - totally integrated power module does . It's part of the under hood fuse box. The fuel pump relay is a non - serviceable relay , soldered directly to the circuit board . Your best bet would be to take it to the dealer . Chrysler , Dodge an jeep have a recall on these TIPM'S .

Sounds like you are a little more knowledgeable than the average bear looking for help here. Yes, these body control modules fail without warning and there is no testing them. The only other thing you might try before shelling out the dough for a new one would be to unplug it, make sure the terminals don't look funky (it doesn't take much corrosion to stop the low voltage going through these terminals) plug it back in and see if it goes back to working (don't hold your breath but it's worth a try.

Chrysler has a service bulletin on these codes along with a software update. Contact the dealer that did the throttle body replace and ask if they did the software update. If not, have them do it. If that fixes the problem, have a little nose-to-nose discussion with the service manager about getting a partial refund on their initial diagnosis

hi,

sounds like the sending unit rheostat(sending unit) has a bad contact or break in the resistance wire. inside the tank theres a float attached to an arm that goes to a small rheostat, like a volume control on a stereo. the rheostat is sending a scratchy signal or no signal to the computer and your getting these readings. that part is inside the gas tank, the part usually comes integrated with the fuel pump. the gas tank has to be lowered to fix it.

Tribeca vacuum pump is prone to impeller failure, plastic simply cracks. Remove the pump and test it with 12volts. If it spins and draws vacuum, that is not your problem. If it works then you have to have a mechanic inspect your pressure sensor.

these people had the same issue:
er bb or er 66 error message on 2006 Tribeca B9 SB9T com

the dreaded P0507, have you had your throttle body cleaned lately? I did clean a neighbors TB while doing other maintenance things to it, and this popped up-and it was miserable getting rid of it. You have to do a 'relearn' procedure (about a million times or so, it seems) and DO NOT take it to a dealer-they will just charge you $100 and tell you to install a new throttle body (not cheap). They know this is a problem, and act like you have done something wrong for merely cleaning a dirty TB. It can and will go away if you do the 'relearn' procedure-read this post for information on how to fix it. it is just annoying but does not have to cost anything to correct. His took MONTHS to reset, but it did, and I did a lot of research on this and can assure you it is not what the dealer would have you think it is-they will try to separate you from your money for this code. read this:

There is a technical service bulletin to correct this condition. Replacement of the car's Electronic Control Unit (the computer) will cure this. Take it to a Toyota dealer and have them replace it for free.

Hello, I know exactly what your talking about! and why no one else did... The error code is being displayed on your trip/odo LCD screen at the bottom of your right gauge pod if I remember correctly. Only, it\'s not Er 66... it\'s (Er bb) which is a malfunction with your vacuum pump system. I truly hope this is the same concern you are asking about, if so I am happy I could help. If it is a different problem please let me know so I can look into this matter further. I\'ve added an "error chart guide" so you will have proof this time when/if you decide to return to the dealer... Good luck!! and I hope this info helps...(subytech1)...

This is a communication error with the BIU (body integrated unit). Need to take to the dealer, possible that the ECU needs to be replaced to fix this issue. It should be covered under the federal emmission wrty.
