Hi, I've also getting this code intermittently, I've changed the MAF and the upper and lower Lambda sensor. 

Anymore ideas?

Hello Michael,

 

Welcome to the Forum.

Hi Michael did did you replace the upper lambda sensor with a aftermarket or genuine one reason asking is the upper one is a fuel ratio sensor not a lambda sensor 

Manual shows the the sensors are the same part number. So bought two RIDEX parts.
