When the purpose is actually V6 models, it is important to be careful because installing the new CKP sensor the old CKP sensor will have to be restarted at a STAR DIAGNOSIS unit to verify the correct engine operation. The sensor is mounted on the upper left rear part of the engine block and would be hard to reach as it has tight spaces. The front cover and engine cover/air filter housing should be removed first in the models of 2001 to 2005 that have an integral engine cover and in all models since 2006. Turn to the left aspect of the engine and reach the CKP sensor, it may be necessary to unscrew the MAF/IAT sensor and the air intake duct that has an arm-shaped form and increase the space. Unionize the electrical connector of CKP sensor using release tab and take off the sensor mounting bolt after which, remove the sensor off the engine. Installation is in the opposite order. But in four-cylinder models, the re-initialization of the new CKP sensor would not work the same way. It happens to be on the upper left rear of the engine block. Start by getting the vehicle safely lifted on jackstands and the lower engine cover removed. Take the electrical connector out of CKP sensor, and loosen the mounting bolt and sensor, and install it back as the reverse.
