  Q: How to replace the Camshaft Position Sensor on Chevrolet Tracker?

  A:

  The first step for replacing the Camshaft Position (CMP) sensor entails disconnecting both the CMP sensor electrical connector and the ground strap. Contine by removing the CMP sensor retaining bolt from the sensor before taking out the CMP sensor. You need to apply a minimal coating of engine oil to the O-ring of the sensor right before you install the CMP sensor . The retaining bolt requires tightness at 9 N.m which equals 78 lb in. The last step involves reconnecting the CMP sensor electrical connector along with the ground strap.

  Q: How to service the camshaft position sensor on Chevrolet Tracker?

  A:

  Service of the Camshaft Position Sensor begins by unplugging the electrical connector from the camshaft position (CMP) sensor. Use a permanent marker to mark the housing of the cmp sensor and the Cylinder Head and afterward move the cmp sensor housing bolt from the Cylinder Head and carefully remove the sensor . Place a new o-ring on the cmp sensor housing before installing it with engine oil lubrication. Avoid applying force to the installation of the cmp sensor housing because the offset drive coupling needs to interact with the offset slot on the camshaft. Position the offset coupling of the cmp sensor while aligning it with the drive slot before putting the cmp sensor housing into the Cylinder Head . Make sure to maintain proper alignment of the offset coupling throughout installation. Fasten the cmp sensor housing bolt but do not fully tighten it before turning the housing until the alignment marks meet. The cmp sensor housing bolt should be tightened to 15 n.m (11 lb ft) before reattaching the cmp sensor electrical connector. The last step is to apply a timing light to verify ignition timing.
