Hey Im fairly new with ls400 and this forum, but I'm hoping you guys would be able to help me out.

My Car is a 1991 Ls400
I was driving home and my check engine like came on and the trac/off came on as well. The traction control stopped working at the same time this has happened.
I went and check for the codes

For Trac I got 51
Check Engine I got a 71

Anyone care to point me at the right direction on what steps I need to do to fix this?

 

According to http://www.lexls.com/tutorials/intro/codereading.html , CEL 71 = EGR system malfunction

That could be causing the TRAC code.

 

Should I go ahead and clean the EGR system? do you think it would help?

 

at this point in time, no-one can tell you how to turn off the trac light, with out disconnecting the battery.
I am now considering removing the cluster and taking the bulb out....
cheers....

 

What should I check in the Egr system to see what's malfunctioning?

 

do a search on EGR system , and see what others have done.

that is really what this forum is all about...... AND tell others how you fixed it.

 

^ will do thanks!
going to be changing my spark plugs/wires and temp sensor. I read on lexls.com that cleaning the throttle body fixed the code on some, so i will try that one out and see if it helps
