A small bit of information for anyone with this fault code. There is a pipe coming from the exhaust manifold going to a pressure sensor at the front of the valve cover. This pipe chokes with soot, blocking the supply and generates this Lo3 code. Disassemble everything and clean out the parts. Reassemble and run the machine for a few minutes Turn ofF the key for 30sec and the code should be cleared on startup
