• Q: How to remove the Knock Sensor on 2009 Toyota FJ Cruiser?

  A: The first step to remove a Knock Sensor for the 1GR-FE engine requires discharge of fuel system pressure. Start with the chain sub-assembly removal before proceeding to remove the No. 1 cool air inlet. 4WD models require the removal of exhaust pipe stopper bracket before taking off the No. 2 front exhaust pipe assembly and front exhaust pipe assembly. The next step requires removal of the manifold stay and exhaust manifold sub-assembly RH. Start by detaching both fuel pipe sub-assemblies before taking off the intake manifold and water by-pass joint RR. The technician should start by extracting the camshaft timing gears and No. 2 chain for Bank 1 before moving to the No. 2 chain tensioner assembly and Bank 1 camshafts. First extract the No. 2 camshaft bearing before proceeding to remove the cylinder head sub-assembly together with its gasket. Separate the heater water inlet hose from the water outlet pipe before removing the No. 1 water outlet pipe by removing its wire harness clamps and its securing bolts. The process ends with knocking sensor connector disconnection and the removal of two knock sensors which is followed by the dismounting of these sensors with their corresponding bolts.
