Often is the case with getting fault codes, they send you on a wild goose chase!

P1656

[39]

VVT signal

[OCV+, OCV-]

Poor output when driving high

speed

· Wiring and connector (oil control valve)

· Oil control valve

· Engine control computer

· +B2 voltage check

Something to do with the VVTi system..
