Technical Lean to rich sensor (v) Fail

[steef12111]

Hi all,

My better half told me she saw a warning about the left front wheel. I went to read out the car via ODB port. Could not find any error code, but while I was at it, I checked all things. I noticed this lean to rich sensor (v) is in fail status. The test value falls within the min and max value, so I am a bit confused on how to interpret this.

Anyone that can help me with understanding this?

Thanks in advance!

Not sure whether it can be related, but seemed that the timing was giving negative values (not sure, but that seems odd to me)

Use normal OBD interface (not cheap universal toy, they're all almost useless) and Fiat specific software (MES, AlfaOBD) that handles TwinAir.
Check the emissions (inspection station/shop, ask for exhaust check only, not The Inspection), take a print (results).
Then we can judge what's really going on. Or, one of the two (which you can do first: exhaust analysis or get trustable OBD data - plot the values, graph, both sensors).

PS
Nope, you don't "fix" a car based on OBD data only (sometimes you can, but this is not professional approach, rather DIY hack method, 50% success rate).
Is it "obvious" that sensor is bad (needs replacing) - will see...

Thanks for the reply. Will see if I can get such report.
As of the recommendation for the OBD interface, I do have an OBDLink LX laying around. Might give this a try to connect it to MES software.
