Q: Where is the CMP sensor mounted and what are the steps for its removal and installation on Honda Fit?
A: The CMP sensor is mounted in the cylinder head on the firewall side of the engine toward the driver's side, with the electrical connector accessible from below the throttle body. For models from 2009 or later, the cowl cover and lower cowl need to be removed. Next, the air filter housing should be taken out. After disconnecting the electrical connector from the CMP sensor, the mounting bolt can be removed, allowing the sensor to be pulled out of the cylinder head. Installation follows the reverse process, ensuring a new O-ring is used (lubricated with clean engine oil) and the sensor mounting bolt is tightened to the specified torque.
