DETAIL

Improvements have been made to the retention of the crankshaft position (CKP) sensor and the CKP sensor heat shield on vehicles within the above VIN ranges. New bolts have been introduced into production which hold the CKP sensor and a new heat shield in position more securely.

The diagnostic steps and repair procedures detailed in this bulletin were developed as an element of the Land Rover Way OPERATION PRIDE. This TIB provides a library location for PRIDE information within the Land Rover North America technical literature system.

ACTION REQUIRED

If the crankshaft position sensor is found to be loose or if it is replaced for any reason, the improved bolts and a new improved heat shield should be installed.
