Title: EML light on permanently!
Post by: stuk50 on 18 April 2012, 21:43:14: Hi,
My first post here!
I have a 51 plate Omega Elite.
Over the past few weeks the EML light has been on. Computer says it is the Cats.
Have changed those. No change.
Changed cat sensors - no change.
Changed mass airflow sensor - no change.

Car seems to run absolutely fine - no problems at all with EML on.
Concern of course is if I get a real problem - how will I know?

I have come to the conclusion that it could be an electrical fault - but where?
I am not a mechanic of any sort but would appreciate some (helpful) advice.
I am not looking for - take the bulb out or get rid of the car!
Thanks :(

Didn't think the 2.6/3.2 ones were worth anywhere near as much as the earlier V6 ones?
Title: Re: EML light on permanently!
Post by: TheBoy on 22 April 2012, 09:28:10: stuk50 - those cat efficiency codes (0420 and 0430) happen when the starting cats start to fail, common on 3.2.

The 3.2 (and 2.6) has 4 cats, and 4 O2 sensors, 2 each per bank:

Engine --- Sensor1 --- Start Cat (Precat) --- Sensor2 --- Main Cat --- exhaust

The solution is to move the 2nd sensor (on each bank) back behind the Main Cat:

Engine --- Sensor1 --- Start Cat --- Main Cat --- Sensor2 --- exhaust

About £15 for the required plugs and bosses, and find someone who can weld.
