Q: How do you disconnect, remove, and replace the Crankshaft Position (CKP) sensors on Lexus RX330?A: For four-cylinder models, start by disconnecting the negative battery cable. The CKP sensor is situated on the timing chain cover next to the crankshaft damper pulley. Disconnect the electrical connector, which is to the right of the exhaust manifold on four-cylinder engines. Raise the front of the vehicle and secure it on jackstands. Remove the CKP sensor mounting bolt to take off the sensor. Installation is the reverse. In V6 models with 3.0L and 3.3L engines, disconnect the negative battery cable, disconnect the electrical connector from the CKP sensor, and remove the sensor mounting bolt. For 3.5L engines, follow the specified steps to access the CKP sensor located at the front tower's right corner. Disconnect the sensor's electrical connector and remove it. In 2GR-FKS models, raise the right side of the vehicle on jackstands, remove the left exhaust manifold, engine oil cooler hose bracket nut, and sensor shield bolts. Slide out the bracket from under the oil cooler hoses, disconnect the sensor's electrical connector, remove the sensor, and apply clean engine oil to the O-ring before reinstalling and tightening the retaining bolt securely.
