GX460 P0390 code on 2011 build (1 Viewer)

[Tquiroz]

The Rig threw a P0390 code. Took it in and the techs replaced the camshaft sensor and wiring harness. After a couple of hundred miles the Rig threw the same code. The code comes and goes. Took it back to the techs and they are stumped. The engine runs fine.

Any advice?

FSM says this for 390

An easy quick thing to check is the wires at your camshaft sensor plugs, mine came out when messing around in the engine bay and threw that code. Seems odd they'd actually replace the wiring harness, even if so I'd double check the connections.

Also make sure all the contacts within the plug are are fully interfacing, e.g. male contacts are fully contacting the female contacts. Maybe blow them out with a little air if there's any gunk/dirt inside the plug. Just some thoughts.
