At high speeds sometimes my check engine light and traction control lights come on and stay on while the power is reduced. The error code is P0394 and one suggestion for this code was to replace the Cam sensor B, bank 2. This did not fix the issue and I am at a dead end. Has anyone else had this issue and been able to correct it? I can drive around town mostly with no issue, but at highway speeds this happens and with the traction light on the power is cut drastically!! Thanks in advance for any help!!!
