Poor engine running, lack of power, and engine oil leak – Subaru XV


We are experiencing some faults with a 2013 Subaru XV 1.6. The faults include poor engine running, a lack of power and an engine oil leak from the front of the engine. We have carried out some basic checks on the air and fuel systems and checked for any stored trouble codes. None were present.


The faults are due to engine oil ingress into the camshaft position (CMP) actuator wiring harness multi-plug caused by the CMP actuator leaking. This fault affects several Subaru models with FB16/FB20/FB20 DIT/FB25/FB25A engine codes. Check the camshaft position (CMP) actuator wiring harness multi-plug for oil contamination and clean or replace the wire terminals as necessary. If traces of engine oil are present, inspect the production number on the camshaft position (CMP) actuator (see Fig 2.1). If the first five digits of the production number are before 17158, fit a modified camshaft position (CMP) actuator. Carry out a road test to ensure the faults have been eliminated.
