Guest Bruce Bowen Posted April 1, 2009 Report Share Posted April 1, 2009 At ETM upgrade + 300 miles my CEL came on. Code read was P0172 (Engine too rich). I'll be checking my air intake hoses and ETM gasket for leaks this weekend. Then the MAF in necessary.-Bruce Link to comment Share on other sites More sharing options...

Was a loose hose connection to the backside of the big air intake hose near the throttle module end. Because it was on the backside of the air intake hose, it was hard to see. Why unmetered air would cause an engine rich condition instead of lean is one of those Volvo mysteries without any clues, causing one some night blues ...-Bruce Link to comment Share on other sites More sharing options...
Ghost Shadow Posted December 26, 2009 Author Report Share Posted December 26, 2009 Its been almost 9 months since i had the ETM issue. UPDATE: I have logged almost 9000 since this install and never looked back. NEVER DID i get any other problems related to the ETM. I did replace the AWD tranny 6000 miles ago, 5 coil packs, 3 oil changes, and put gas in it. If you like dealing with the dealer, then try and get it warrantied. If not, it going to be money well spent! BTW- tranny did not die from the ETM, i did not put Loctite (thread locking solution) on the torque converter bolts when i reinstalled it with the new engine. :D Link to comment Share on other sites More sharing options...
