regalman Posted August 12, 2011 Report Share Posted August 12, 2011 (edited) I have the 94 regal with the 3800 VIN L motor. I read on the net that it might be OBD2 instead of 1. It has the upstream and downstream O2 sensors, it has a MAF but I do not think it has a MAP. Does anyone know what version it is OBD1, 1.5 or 2?

Dark Ride Posted August 16, 2011 Report Share Posted August 16, 2011 OBD II had not come out by 94 so it can't be that Quote Link to comment Share on other sites More sharing options...
Timm Posted August 23, 2011 Report Share Posted August 23, 2011 ^^Correct^^ The 3800 Series 1's were never produced along with OBDII as far as I know. I'm going to say I'm 75% sure you're OBD1, but really there's no real difference between 1 and 1.5 besides a couple extra sensors and engine codes.
