Where is the valve position sensor located?

It is the intake manifold runner control (IMRC). This is located in the intake manifold on the passenger side. The power steering pump and alternator are close to it making difficult to access. The control solenoid is bolted to the head right by the fuel rail.

YOU MAY WANT TO HAVE IT REPLACE BUT MAKE SURE THEY CK THE CIRCUIT BEFORE REPLACING ANY PARTS
