For four-cylinder models, start by disconnecting the negative battery cable. If needed, remove the engine cover and air intake duct for more workspace. Disconnect the electrical connector from the CMP sensors. To remove the CMP sensor from the cylinder head on a 2AZ-FE engine, disconnect the electrical connector and the sensor mounting bolt. Remove the sensor, checking the O-ring's condition; replace if damaged. Installation is the reverse. For V6 models, begin by disconnecting the negative battery cable and removing the engine cover. The CMP sensors on 3.0L and 3.3L engines are located on the left ends of the front and rear cylinder heads. Disconnect the electrical connector from the front CMP sensor and remove its mounting bolt. For the rear CMP sensor, loosen the wheel lug nuts for the front left wheel, raise the vehicle, and remove the wheel. Turn the steering wheel right, locate the sensor between the transaxle bellhousing and stabilizer bar, and remove it as previously described. Installation for both front and rear CMP sensors follows the removal steps in reverse.

On 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.
