Which Lambda Sensor?

[COLZO]

When faulty which lambda sensor causes the Exhaust Gas Monitor Light to come on?

There isn't an exhaust gas monitor light?

You are probably thinking of the engine management light that tells you of all sorts of problems with the car.

Yes there is!

 

[M26]

If it's that yellow one, its the engine management light.

It needs plugged in to a code reader as it could be any number of things.

 

[COLZO]

Yes it is that light. According to handbook its the EXHAUST GAS MONITOR WARNING LIGHT

The post cat sensor. If it's on constantly

Not necessarily. Mine is often on due to the knock sensor. You need to get the codes read.
