PID identification

[AK47]

Hi everyone.

Just used FORScan for the first time today, and I was hoping if someone could clarify a few issues.

Regarding the PID - DP-DPF, kpa, I have 2 seemingly identical PID's associated with the pressure variable, one appears to be differential pressure, which fluctuates, the other is static at 285kpa.

I've attached a picture to clarify.

Is this a historical maximum or something?

Any help is appreciated.

Yes, there are 2 different PIDs for differential pressure on Transit Connect 1.8 TDCi 2009 model year. However both are marked in our database as differential pressure (not any statistical PID). We have no idea why one of them shows obviously incorrect value (in fact 285kPa is not possible for differential pressure, even 18 kPa is not small). If you send us internal FORScan log, we will ivnestigate. Instruction is on Contact Us page.

Thanks.

logs emailed.

Ok, just to add, I managed to scan another Connect today with same engine configuration, and the same anomaly is evident, 4kpa dynamic on 1 PID, 293kpa static on the other.
Hope this info helps.

Thanks for the logs.

The second PID (the one that shows big stati values) seems to have wrong scaling. But for now we don't know right scaling for this PID on this model. So please ignore it for now (we can disable it or rename it, to do not confuse users).
