Engine Management Light On

Can anyone help, the engine management light has come on on my wife's ZR

Last week we had a new exhaust put on, the CAT part of the exhaust could this be the reason it has come on.
Car seems fine otherwise, can it be driven ?

What about wiring for the lamda sensor, is that ok?

If you join this facebook group, and come over to a meet, i am sure me or others will have a code reader to check the codes for you.

Hi Dave,
Already belong to this group. (under my mrs name)

As far as i am aware the wiring is okay for the sensor, has been fine since had done last Thursday but only came on today, been to garage today who fitted exhaust they checked it out and was okay, but they do not have facility to check codes

Iirc non gen cats are prone to this and even if you re-set the faults the light will be back on,not a MOT failure if the emissions are ok

Following recent changes any warning light that doesn't come on and go out properly is now a fail.
