2009 Toyota Matrix Knock Sensor Parts Q&A

• Q: How to remove the knock sensor on 2009 Toyota Matrix?

  A: You need to discharge fuel system pressure before you can begin removing the knock sensor of the 2AZ-FE engine. Next, drain the coolant. Proceed by removing the front wiper arm head caps before taking off both front wiper arm and blade assemblies from left and right sides. Continue by removing the hood to cowl top seal followed by detaching the cowl top ventilator louvers from both right and left sides. The next step is to detach the windshield wiper motor assembly together with the link components followed by separating the outer cowl top panel. The suspension tower damper assembly becomes removable when the vehicle has front strut bars. You need to remove the No. 1 engine cover sub-assembly together with the air cleaner cap sub-assembly that includes a hose. First remove the throttle body assembly before disconnecting the fuel tube sub-assembly to take away the fuel delivery pipe sub-assembly with its fuel tube sub-assembly. The procedure for intake manifold removal consists of disconnecting ventilation hose and union to check valve hose and separating wire harness clamp from the intake manifold. Detach the five bolts together with two nuts and the intake manifold gasket and the intake manifold. Remove the No. 1 intake manifold insulator as the final step. To finish remove the connector of the sensor then unfasten its mounting nut and sensor.
