I replaced the front 02 sensors but can detect no difference. The truck runs great and gets the same mileage it usually does. Does anyone have any ideas what to look for? Code 2 I get 1317 (ABS rough road line low fault)at regular intervals no mater what I'm doing. Any ideas there? Thanks Gordon   gordon sitts (Gsitts) Member Username: Gsitts Post Number: 82 Registered: 10-2002 Posted on Tuesday, February 24, 2004 - 04:59 pm:    I'm still hoping some good hearted LR tech can give me a steer Please!!!

Anyone else have any input?

I had the same code on y 96 D1. It is also known as bank 2 (I think). If I am wrong, somebody please correct me. So if you replaced the front ones you may have replaced the wrong one.   gordon sitts (Gsitts) Member Username: Gsitts Post Number: 83 Registered: 10-2002 Posted on Wednesday, February 25, 2004 - 06:42 pm:    I did the sensor change for other reasons it just happened to occur in the middle of this codes mess. I just didn't see any changes in the codes but you might be right about it being part of the problem. Does anyone know which code is connected to which sensor that might help Thanks G
