Hello all, working on a komatsu wa380-8 with a terrible squeal and codes for nox sensor outlet abnormalities, the squeal Is coming from engine bay and cannot distinguish from where, wondering if anyone else has had this?
Code is ca3545 and cannot seem to find in komatsu service manual anywhere with this code were also having a loud squeal/whine from engine, can’t seem to find an issue but wondering if it could be an exhaust manifold leak
