Damaged Camshaft Position Sensor (CMP) Causes the MIL to Come On
With DTC P0344
(Supersedes 09-042, dated December 7, 2010, to revise the information marked by the black bars and asterisks)
*REVISION SUMMARY
Under PARTS INFORMATION, part application year range was changed.*
SYMPTOM
The MIL comes on with DTC P0344 (camshaft position [CMP] sensor intermittent interruption).
PROBABLE CAUSE
Excessive camshaft end play causes the camshaft gear to damage the camshaft position (CMP) sensor.
CORRECTIVE ACTION
Replace the front camshaft, the thrust cover, the cam gear, and the CMP sensor.

REPAIR PROCEDURE
NOTE:
This procedure is in an outline form that you can also use as a checklist for the repair. If you need more details, confirm the proper service manual, or view them online:
^ Camshaft Inspection
^ Camshaft Replacement
^ Timing Belt Removal
^ Timing Belt Installation
1. Remove the battery.
2. Drain the engine coolant.
3. Disconnect the upper radiator hose from the engine side.
4. Remove the exhaust gas recirculation (EGR) valve.
5. Remove the EGR valve studs.
6. Remove the air cleaner.
7. Remove the battery base.
8. Remove the intake air resonator.
9. Raise the vehicle on a lift. Remove the right front wheel and the right front inner fender.
10. Turn the crankshaft pulley clockwise so its white mark lines up with the pointer on the front upper cover.
NOTE:
The other pointer is not used.
11. Check that the No.1 piston top dead center (TDC) mark on the front camshaft pulley and the pointer on the front upper cover are aligned.
NOTE:
If the marks are not aligned, rotate the crankshaft clockwise 3600, and recheck the marks.
12. Remove the drive belt and the drive belt auto-tensioner.
13. Remove the crankshaft pulley.
14. Remove the front upper cover and the rear upper cover from the engine.
15. Remove the lower cover from the engine.
16. Remove one of the battery clamp bolts from the battery tray, and round the end of it with a file or grinder.
17. Thread the battery clamp bolt in to hold the timing belt adjuster in its current position. Tighten it by hand; do not use a wrench.
18. Remove the intake manifold.
19. Remove the three front ignition coils.
20. Remove the front bank cylinder head cover.
21. Remove the front rocker arm with spool valve assembly.
NOTE:
Leave the bolts in place on the rocker shaft to hold the springs and washers on the shaft.
22. Remove the front camshaft pulley, and the back cover.
23. Remove the CMP sensor from the back cover.
24. Inspect the CMP sensor and the inside of the camshaft gear for signs of contact.
^ If no contact is noted, check the camshaft endplay.
^ If the camshaft endplay is out of specification, proceed with step 25. If it is in specification, then this service bulletin does not apply. Proceed with normal troubleshooting.
25. Remove the camshaft thrust cover, then carefully remove the camshaft. Place a rag below the thrust cover opening, and along the top of the transmission, to catch any residual oil that flows from the opening, and off of the camshaft.
26. Install a new camshaft seal.
27. Install a new front camshaft with a new thrust cover and 0-ring.
28. Install a new CMP sensor.
29. Apply engine oil to the threads of the camshaft pulley mounting bolt, then install the new front camshaft pulley. Torque the pulley mounting bolt to 90 N.m (67 lb.ft).
30. Set the front camshaft pulley to TDC by aligning the TDC marks on the camshaft pulleys with the pointers on the back covers.
31. Install the front rocker arm assembly, then tighten the mounting bolts two turns at a time, in the sequence shown, until they are all torqued to 24 N.m (17 lb.ft).
32. Remove and clean the timing belt pulleys, the timing belt guide plate, and the upper and lower covers.
33. Make sure the timing belt drive pulley and the camshaft pulleys are still at TDC by aligning them as shown in steps 10 and 11.
34. Loosely install the idler pulley with a new idler pulley bolt so the pulley can move but does not come off.
35. Install the timing belt in a counterclockwise sequence, starting with the drive pulley. Take care not to damage the timing belt during installation.
36. Tighten the idler pulley bolt to 44 N.m (33 lb.ft).
37. Remove the battery clamp bolt from the back cover.
38. Install the lower cover. Tighten the bolts to 12 N.m (8.7 lb.ft).
39. Reinstall the front upper cover and the rear upper cover. Tighten the bolts to 12 N.m (8.7 lb.ft).
40. Remove any oil, and clean the pulleys, the crankshaft, the bolt, and the washer. Lubricate with new engine oil as shown.
41. Reinstall the crankshaft pulley, then tighten the bolt:
^ Hold the pulley with the holder handle and the holder attachment. Tighten the bolt to 64 N.m (47 lb.ft).
^ Mark the bolt head and the pulley as shown, then tighten the bolt an additional 600.
42. Rotate the crankshaft pulley six turns clockwise so the timing belt positions itself on the pulleys.
43. Turn the crankshaft pulley so its white mark lines up with the pointer as shown in step 10.
44. Check the camshaft pulley marks as shown in step 11.
NOTE:
If the marks are not aligned, rotate the crankshaft clockwise 3600, and recheck.
45. Reinstall the drive belt auto-tensioner and do the bleed procedure (2007 J35A7 engine shown).
^ Attach a socket wrench to the drive belt auto-tensioner from above the engine.
^ Slowly (for at least 3 seconds) compress the auto-tensioner, in the direction shown, until it bottoms out.
^ Release the auto-tensioner, then compress and release it three more times.
46. Reinstall the lower half of the side engine mount bracket. Then reinstall the upper half of the side engine mount.
47. Reinstall the drive belt, routing it as shown (2007 J35A7 engine shown).
48. Check and, if needed, adjust the valve clearance on cylinder's number 4, 5, and 6.
49. Reinstall the front bank cylinder head cover.
50. Reinstall the three front ignition coils. Tighten the bolts to 12 N.m (8.7 lb.ft).
51. Reinstall the intake manifold with a new gasket. Tighten the bolts and nuts sequentially in three steps.
52. Install the upper cover with a new gasket. Tighten the bolts and nuts sequentially in three steps.
53. Reinstall the EGR valve studs and the EGR valve with a new gasket (2007 J35A6 and J35A7 engines shown).
54. Reconnect the upper radiator hose.
55. Reinstall the intake air resonator and the battery base (2007 model shown).
56. Reinstall the air cleaner housing (J35A7 engine shown).
57. Reinstall and reconnect the battery.
58. Reinstall the inner fender and the front wheel. Torque the wheel nuts to 127 N.m (94 lb.ft).
59. Fill the radiator with coolant, and bleed the air from the cooling system with the heater valve open.
60. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure:
^ Connect the HDS to the data link connector (DLC) located under the driver's side of the dashboard.
^ Turn the ignition switch to ON (II).
^ Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, troubleshoot the DLC circuit.
^ Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS, and clear the CKP pattern.
^ Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.
