How to adjust VVT
Hi everybody. This is the first time to be in this forum. I need help.
I have a 2004 Volvo S60. Vin# YV1RS59V342389119. I did head gasket work. Now, I have code 643A (for this engine, B5254T2, ECM code 643A is for Intake camshaft position). I tried some information from the Internet, but was not enough. I replaced the camshaft position sensor and clean the VVT solenoid, but I now, I am thinking to adjust and/or replace the variable valve timing (VVT) unit for the intake side.
Anybody can offer any help.
