P0155 error code gmc savana - 2006 GMC Yukon

SOURCE: 1999 GMC Savana Heater

Need to check your coolant level, that is the first culprit...It has to be full in order to circulate in the heater core...

SOURCE: gmc savana van will stop running while driving or start sputterin

It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.

SOURCE: 2005 GMC Savana ,where is the OBD-2 link?

They are typically located at the right or left side of the steering column under the dash at the sound panel. Look at the sound panel and you will see a hole in the panel and the connector should be visible.
Let me know.
