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. 5. Do the Idle Learn Procedure: • Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are turned off, then start the engine. • Let the engine reach its normal operating temperature (the cooling fan cycle twice). • Let the engine idle (throttle fully closed and with all electrical items off) for 10 minutes. 6. If you are working on a 2001 Civic 2-door EX, do the Cruise Control Learn Procedure. • Drive the vehicle, and set the cruise control above 40 miles per hour. • Continue driving the vehicle for 5 to 10 minutes. NOTE: You can use a smog/chassis dynamometer to do this step instead of driving the vehicle. Do not do this step with the vehicle on a lift.
