ebp sensor is right behind the high pressure oil pump reservior and in front of the filter assembly toward the passenger side. it has a small tube running down to the exhaust manifold. this doesn't ussually cause the cel to come on nor does it casue drivablilty problems. the p0279 on the other hand will cause problems.
