Question 1

What actions should you take if replacing the Crankshaft Position Sensor triggers a Diagnostic Trouble Code (DTC) on Mazda 6?

Accepted Answer

Some models may program a Diagnostic Trouble Code (DTC) on changing the CKP sensor. In case it does, and you have a generic scan tool that is able to clear codes, erase the code and run a check to see whether it has vanished or is still present. In case it does, one should use a dealer service department to carry out a Misfire Monitor Neutral Profile Correction on the factory scan tool. Start with the disconnection of the cable to the negative battery terminal. On models other than 3.7L V6, loosen the front right lug nuts and then jack up the front of the car and secure it on jackstands. Take off the right front wheel and the access panel on the lower part of the fender beneath the bigger splash cover. In case of 3.7L V6, raise front of the car and place it safely at jackstands and remove engine under cover. The CKP sensor is fitted on the back of the timing chain cover at the lower rear part just behind the crankshaft pulley. Install the No.1 cylinder in Top Dead Center (TDC). Unscrew the CKP sensor mounting bolts, disconnect the electrical connector, to the CKP sensor and remove the sensor. When fitting a new CKP sensor, then it includes an alignment jig that is unique to the sensor but an aftermarket one may be sufficient. In case the CKP sensor had to be removed to get to another component, apply the other method of aligning the CKP sensor. Attach a 6 mm 18 mm bolt in the threaded hole that is in the crankshaft pulley and screw into the timing chain cover. Install CKP sensor and leave the sensor mounting bolts loose. In case of new installation of a CKP sensor, follow as follows: place it with the special alignment jig as per the instructions provided by the manufacturer, screw the CKP sensor bolts firmly and then take away the alignment jig. When replacing the old CKP sensor, note the sensor trigger wheel or timing plate attached on the back of the crankshaft pulley with the blank spot on that side of the timing plate. Then number five teeth in an anti-clockwise direction of this blanked area followed by a straight line, passing through the middle of the crankshaft pulley. Install CKP sensor: Line made, center of the CKP sensor is then mounted in position by tightening of sensor bolts. Unscrew the Crankshaft pulley bolt which was previously fixed, take off the special timing tool and fit in the cylinder block plug. Removal is otherwise the opposite of the installation. In V6 models that have a 3.0L engine, unscrew the CKP sensor mounting bolt, and detach the electrical connector of the CKP sensor. Check sensor O-ring and change it in case it is cut, torn, or worn. Wipe sensor O-ring with clean engine oil. On the engine block, the CKP sensor is positioned on the left front side of the engine block just next to the transaxle; in the case of the 3.7L engine. Take out the upstream and downstream oxygen sensor of the catalyst converter of the front head, then take out the catalyst of the front head. Take out the mounting nut and the heat shield of CKP sensor. Take off the rubber grommet cover, fully loosen the CKP sensor mounting bolt, and take off the sensor and bolt as one, bearing in mind that the sensor mounting bolt and sensor are a single piece. Unplug electrical connector of CKP sensor on sensor, and plug electrical connector of CKP sensor on sensor, and fit sensor. Removal is otherwise the opposite of the installation.

Question 2

How to remove and install the Crankshaft Position Sensor on Mazda 3?

Accepted Answer

The first step is to remove the battery cover and disconnect the cable of negative battery terminal in order to remove the CKP sensor. The next step is to unscrew the right front wheel lug nuts, lift the front of the car and place it firmly on jack stands and then remove the right front wheel and the smaller access panel. Install the No.1 cylinder at Top Dead Center (TDC) and remove the electrical connector off the CKP sensor. Unscrew the mounting bolts of CKP sensor and remove the sensor. To install, in case of a new CKP sensor, it is supplied with a special alignment jig, which can be an aftermarket tool as well. There is a threaded hole in the crankshaft pulley that a 6mm x 18mm bolt is installed in and screwed into the timing chain cover. Fit the CKP sensor without screwing the mounting bolts. When a new sensor is used, one has to align the sensor with the special jig as indicated by the manufacturer and tighten the bolts firmly and then take off the jig. In case the old sensor has to be reinstalled, find the blank location on the timing plate, count five teeth anti-clockwise and make a straight line through the center of the fifth tooth along to the center of the crankshaft pulley. Make the CKP sensor in line with this line, and screw the bolts firmly. Lastly, disconnect crankshaft pulley bolt and special timing tool, replace the cylinder block plug, installation of which is reverse to that of removal.
