Changed my coil pack and now my tach quit working, started my car and let it run for a minute, next day it won't start. code PO304 & PO350

Sounds like you didn't quite get everything hooked back up. Double check that all the wires are connected.
what make/model/year? without that, the codes don't mean much.

How do you fix code 1155 on a 2004 Hyundai xg350l with 3.5 v6 dohc

Hi there:

DTC P1155 - A/F Sensor Heater Circuit Malfunction(Bank 2 Sensor 1)

This is a very common code and the front Air Fuel Ratio sensor located in the front manifold will need to be replaced and the codes cleared. Here is a very similar pic to your vehicle...


This is a V6 car so it has 2 heads. They classify Bank 1 as having cylinders 1,3 and 5 while Bank 2 has cylinders 2,4 and 6. The same would be for a V8 engine. 4 cylinder engines only have Bank 1...


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

I have a 2005 xg350L Hyundai, I am geeting a code of po444 when the engine is on and when Ithe engine I don ot get the code of po4444. Could you please tell me that this code is on the charcoal katharsis.

According to the information I have available to me, P0444 is not a valid code for your vehicle. There could be a problem with your code reader or it could be a programming problem with your Engine Control Module.

Fuse box layout

First of all, Hyundai did not produce the XG350 until 2002. You wrote 2001 Hyundai XG350L. The engine in the 2001 is 3.0 (XG300). Cant help you.
