Hey guys! It's been a while... my 850 has two codes coming up P131 and P137. Any help, advice or antidotes would be appreciated.

Thanks!

The code p0131 is coming due a failure in the signal of the Engine speed sensor, this condition are set if the ECU does not receive signal from the RPM sensor for 20 revs of the engine, the possible source is a break on the signal cable of ground lead. signal lead short to ground or voltaje, contact resistance in connector, defective RPM sensor. Start cleaning the connector.
The P0137 is throw by the failure of the Bank 2 O2 sensor, check also the connection for rust. or change it..
