code 28

What code(s) are you getting? Is it a main (as you imply) or sub oxygen sensor? Depending on sensor location, it could be a problem with the cat and not the sensor itself.

And just curious, how many miles are on your car? Symptoms might be lower gas mileage and/or failed emissions test.

It is not as serious as a heart attack but more than a toothache. :) Welcome.

it is one of the main sensor,but theres 2 right? 163k m.

hi everyone, my ls 400 '93 started last night blinking the engine management light at me. So i checked the codes, its an o2 sensor problem .How serious, and what are the simptomes of the main o2 sensors signals deficiency.???thanks

Ok,

If you are confident to read the codes yourself and have a paper clip you don't need a code reader, method and codes are in the link below.

If you get the code(s) post up the results and we'll go from there.

so apparrently the main oxigen sensor signal is the problem .Not knowing what it is ...maybe u can lighten me.thx for the link.really helpfull.

I am having the same problem with my brake light coming on and the brake fluid reservoir is on full and looks clean. Any other ideas on what to check would be appreciated.

Thanks,

Paul

just try to top it of whit brake fluid up to max,if consistant it might be a problem whit your emergency brakes..

Hi and welcome to the LOC, I didn't know I'd become famous on the forum! lol

Before I can help I need to know which year your LS is as the diagnostics are different after October 1994.

it is a year '93. thx
