On affected vehicles, the CVT (continuously variable transmission) drive belt may slip during acceleration. To increase customer confidence, American Honda is extending the warranty for this potential problem to 7 years or 100,000 miles, whichever comes first. This extended warranty covers only CVT drive belt slippage and CVT start clutch judder below 15 mph (see Service Bulletin 07-049, Warranty Extension: CVT Start Clutch Judder). Any other customer complaints with the CVT are covered by the normal 3-year, 36,000-mile new vehicle limited warranty. Do the diagnosis in this service bulletin. Then, only if needed, install a CVT lower valve body kit and update the ECM (Civic Hybrid), or replace the CVT (Civic GX, Civic HX, and Insight).

SYMPTOM MIL is on, and DTC P1361 (TDC sensor intermittent interruption) or P1362 (TDC sensor no signal) is set, or the engine makes a rattling noise. PROBABLE CAUSE Excessive end play in the camshaft. CORRECTIVE ACTION Replace the cylinder head assembly. DIAGNOSIS Remove the valve cover. Check the camshaft for excessive end play. The maximum allowable amount of end play is 0.5 mm (0.02 inch)(see page 6-40 of the 2001–02 Civic Service Manual). • If the end play is more than 0.5 mm (0.02 inch), go to REPAIR PROCEDURE. • If the end play is less than 0.5 mm (0.02 inch), proceed with normal troubleshooting. REPAIR PROCEDURE 1. Remove the cylinder head (see page 6-30 of the 2001–02 Civic Service Manual), and discard it. 2. Inspect the TDC sensor and the timing belt covers for damage (see page 6-57 of the service manual). Replace any damaged parts. 3. Install the new cylinder head (see page 6-50 of the service manual). 4. Check the engine oil level; add oil if necessary.
