faulty LAMBDA sensor 147 1.6 ts 120cv

[rafi532]

Hi,
I'd like to know which one (or more) of my LAMBDA's is faulty.
I attached the screenshot of the FIAT ecu scan.


Thanks

Hi Rafi

Perhaps only one. Cleared stored DTCs?

Which the sensor readings in Parameters?

Alfas 147 petrol should have 2 lambas before catalisator and one after.

1st clear error codes
2nd check connectors (and clean them)
3rd test lambdas with ohm meter
4th test lambdas one more with MES (parameters)

If error appears again than need to change one by one lambda...

OR............ clean them
