The crankshaft position sensor (CKP) times the fuel injection and ignition on the cylinders and if there is a problem area in the relaying of the circuits a DTC is stored. To test the crankshaft sensor disconnect the sensor from the connector and with an ohmmeter test the terminals; because of the location, it is better to test it on bench. This test deals mainly with the crankshaft sensor and if this test yields the right result, this may be due to harm and or damage on the harness or possibly the PCM which can only be diagnosed by a dealer service department or better still a fully equipped repair store. For replacement, first, it is advisable to remove the cable from the negative terminal of the battery. For the 2006 and prior models, the right inner fender splash shield must be pulled out and for the 2007 and onward models, the air conditioning compressor should be taken off. After that, it will be necessary to pull up the crankshaft position electrical connector, relinquish the bolt, and, therefore, separate the sensor. Installation of the pipe is done in the reverse order as that adopted while removing it.
