Lambda Error C-6

[Wolf_Tm250]

A C-1 status (this is not an error) while driving is interesting, I wouldn't be surprised is the sensor was a bit unhappy and was shutting down. The ECU retries the sensor every 10seconds (or so) when it has gone into error, if it comes back ok it will race throught the C-3 status becasue it is already hot and probably the C-2 as well. Need the logging.

Hi Mark, which values do you need to be logged for understanding why it goes into Error ? Zp?

I got it many times today during a track session, and I don't think the Ecu retries the sensor as the Error is in the Diagnostic page AND the closed loop is OFF till I Reset Error...

PS: I made a mistake when I said it was a C-1 error...
In fact I don't know which error is, as in my Car-PC I just get Error Lambda 1 in Diagnostic page...

Thank you.

Need the logging.

Here it is, any advice appreciated.

Thanks.

So you are running closed loop Lambda? If the closed loop lambda maxes out its limits it will go into error (reported as a Lambda error). You should log the Short Term and Long Term trims to see this.

Yes, I'm using closed loop Lambda.
So how would it be possible to avoid this problem of "maxing out its limits"?
Sorry but I don't understand with Closed Loop limits you are talking about...

Thanks
