P1545 Help
 

so my battery cable came diconected whil i was at work and after re-connected my car runs like poo. I searched the topic but still had a few questions. because my car is DBC my understanding is all ihave to do is disconnect the bat for a half hour and then do a tba and it should run right as rain right? or do i have to limp the damn thing 20 miles to the dealer and have them run a vag?

P1545: Throttle position controller malfunction.

you should try cleaning it and checking the connection, otherwise it needs to be replaced.

did u try leaving the keys in AcC for like 5 min with the engine off so the ECU can recalibrate.

yep sure did, did that like four times last night. It is not a dirty TB because it only started after the battery came disconnected, and from my understanding this code can come from the battery being disconeccted or from being jummped. Also i called the dealer and that cant even see me until next week so i need to get this car running again before then!

Where did u come up with that understanding? its a sensor malfunction on the throttle body. i would atleast clear the code with the scanner and see if it comes back before you take it to a dealer.

i came up with that because when i searched every thread i found said that this can occur from a bat disco or being jumped but noone said realy how to fix it.

There have been a couple times with my 00/dbw that after the battery was dead/jumped I had a throtle body code that went away after it was cleared. As for the running like poop. I had my 97 battery disconnected and when I hooked it back up the idle was bouncy after a start but corrected itself after a few drive cycles. Clear the code, drive a few cycles and see what happens.

cool thanks i will take it to AZ have them clear it and go from there

Okay it took two days and alot (i mean alot of research)
if you read above you would know that after having my battery disconnected my car started throwing a P1545 code and running like sh!t.
i think i set the world record for most TBA's in a two day span (about 27)
any way if you get this code here area few do's and don'ts
1) DO NOT BUY A NEW THROTTLE BODY!!!
2) buy a vag com cable (or ebay cable (thats what i used))
3)Down load vag software 409.1 or lower
4)down load drivers and patches for software (for ebay cable(sorry cannot help you there but there is a good article if you google "ebay vag cable" i think its called $20 vag com it will tell you were to go and what to down load)
6)run the vag com TBA
7) go in the house, sit on the couch, crack open a cold one, and watch rocky(or any movie, cus ur done)

i found that this problem can only be solved by using a vag com to recalibrate the connection between your computer and TB, some times doing it with your key can work but not in my case (or many others)
Simple math
1 hour labor at dealer $90
vag com software $99 (with $10 ebay cable) = $100

so for $19 more than the dealer you can have the greatest tool ever made for your car.

ive gotten that code plenty of times after disconnecting my battery and forgetting to do a TBA. you just reconnect the battery, put the key in the on position (dont start it), walk over to your TB and listen for a click. once it clicks, you start the car and your good to go. works for me everytime
