rjhat Posted February 10, 2004 Report Share Posted February 10, 2004 I need to clear this up. I recieved error P0140 on my DIC and most people who replied from this forum agreed that it was the O2 sensor just before the catalytic converter, unless i didn't understand correctly. Anyway, the parts lady argued with me saying that it was the POST catalytic converter sensor. My understanding is that bank 1 sensor 2 is the PRE catalytic converter sensor. Can anyone give more info? At this point, I would rather believe you guys the parts "expert"! Thanks. Link to comment Share on other sites More sharing options...
rjhat Posted February 10, 2004 Author Report Share Posted February 10, 2004 Oh yeah, I also got a P1139. I believe this is referring to the same sensor. But I have a totally different code, 2118. I dont remember the letter that came before. Does anyone know what this code is? It was in the MSM listings. Is this (M)agna(S)teer (M)odule? Just a guess.

98Concours Posted February 10, 2004 Report Share Posted February 10, 2004 The 2118 code would be B2118: Front Vertical Sensor Failed. MSM is the memory seat module. Jeff 98 Concours 90 Seville 04 Corvette Link to comment Share on other sites More sharing options...
