Lambda, fuel flow rate and fuel consumption - OBD2 PID?

Hi guys,

Does anybody know the PID/channel for lambda, fuel flow rate and real time fuel consumption? I´ve tried in several cars the list below but it has not worked:

Thanks again,

Hi, those sound like non-standard (non SAE) PIDs? If so, you'll need to get that from the OEM - or from reverse engineering elsewhere. Non standard PIDs won't be listed on that page.

Actually they are standard SAE OBD2 PID, using th website above. For example, RPM is PID 12. It is waht i find on RCP. And fuel rate would be 94, however it shows nothing. Would you have any tip?

If the ECU does not respond with a value, then that means the ECU does not support that PID. It's important to remember that ECUs may not support all PIDs.
