Using IDS, verify that DTCs are present.
2. Verify the vehicle build date.
3. Remove the cam covers.
4. Inspect the part number on the front of the camshaft phaser. You may need to rotate the crankshaft to move the phasers in position. The left cam phaser part number should be 7T4E-6C524-EC, and the right cam phaser part number should be 8T4E-6C524-AC. If either orboth don’t match the updated part numbers, replace the camshaft phasers.
