• Q: How to remove the Knock Sensor on 2010 Scion tC?

  A: The first step for removing the Knock Sensor from the 2AZ-FE engine control system requires the discharge of fuel system pressure. Drain the coolant then disconnect the negative battery terminal cable while waiting for at least 90 seconds because this time period stops Air Bag and seat belt pretensioner activation. The necessary parts for Knock Sensor removal on the 2AZ-FE engine control system include starting with the front wiper arm head cap then removing the front wiper arms (LH and RH) and the hood to cowl top seal along with the cowl top ventilator louver (LH). Before removing the wiper link and cowl top panel outer you need to detach the wire harness clamp then unscrew the seven panel-retaining bolts. Detach the cowl body mounting bracket lower (LH) by removing its bolt and clip before taking out the bracket. The order of removal includes taking out the engine cover together with the air cleaner cap and throttle body and fuel delivery pipe. To access the fuel tube begin by taking off the clamp followed by pinching the retainer then pulling out the fuel tube connector from the pipe while checking for foreign substances and avoiding pipe and connector damage. Remove the heater water inlet hose then proceed to take off the heater water outlet hose. Unplug the brake booster hose connected to the union to check valve hose at the same time as the camshaft timing oil control valve connector and wire harness clamp. Then proceed with separating the hose from its vacuum hose clamp. To begin remove the 5 bolts together with the 2 nuts before taking out the intake manifold and afterward extracting the gasket from this component. Performance of this task requires first removing the intake manifold insulator from the cylinder block while disconnecting the sensor connector and removing the nut and sensor.
