How to disconnect and replace the Camshaft Position Sensor on Mazda 6?

Unplug the cable on the negative battery. On four-cylinder models, the CMP sensor will be installed at the left front of the valve cover at the top of the left end of the intake camshaft. Unattach the CMP sensor electrical connector, CMP sensor mounting bolt and remove the CMP sensor. Check the state of CMP sensor O-ring; in case it is damaged, ripped, or scarred, change it. Removal is the contrary of installation. In the case of V6, observe that each cylinder head has a CMP sensor, which is located on either the right end (3.0L engines) or the left end (3.7L engines). On 3.0Ls, in case of removing the CMP sensor off the head of the front cylinder, lift the wiring harness clip off the valve cover stud and lay it aside. Should the CMP sensor be removed off the rear cylinder head, there is a likelihood that the coolant reservoir will also need to be removed and stored out of the way, but the coolant lines are not to be disconnected. On engines of 3.7L, take out the air filter housing and air intake duct. This is because the front cylinder head CMP will be concealed behind the harness bracket, and this will require the removal of the bracket mounting bolts and the bracket itself. Unscrew the electrical connector of the CMP sensor and delete the CMP sensor mounting bolt and extract the sensor. Take out CMP sensor O-ring and check the condition of it; in case it is torn, broken, or in any other way damaged, change it. Installation: Lubricate sensor O-ring with clean engine oil, and otherwise, it goes in the opposite way as it came out.

How to remove and replace the Camshaft Position Sensor and its O-ring on Mazda 3?

Take the battery cover and unplug the cable at the negative end of the battery. This is followed by removing the upper engine cover by lifting it upwards on each side and removing it on the posts of mounting in the center. Unscrew the electrical connector of CMP sensor and disconnect the electrical connector, unscrew the CMP sensor mounting bolt and disassemble the CMP sensor. Check the status of CMP sensor O-ring, in case it is torn, cracked or, otherwise, damaged, change it. Make sure to lubricate sensor O-ring using clean engine oil and it is the opposite of removal.

Mazda Camshaft Position Sensor

Your Mazda camshaft position sensor is a magnetic sensor that collects data about the camshaft and engine. In other words, it ensures that fuel-injected engines are timed properly and accurately. It was placed on the cam housing. An efficient, high-performance camshaft position sensor enhances the efficiency of your engine. Here are signs that indicate failure of the Mazda camshaft position sensor: if the transmission is stuck in one gear until you turn off and restart the vehicle; if the car jerks while losing power; if there is a noticeable loss of engine power; if acceleration becomes irregular, misfiring occurs, starting becomes difficult or surging; if you find out that engine does not start at all, check your camshaft position sensor immediately because it may need replacement.

Whenever you need replacements, opt for genuine Mazda Camshaft Position Sensors. Because they meet the manufacturer's criteria, it guarantees that replacements fit perfectly.
