5. With the i-HDS, check to see if the PGM-FI and TCU software has been updated by using the J2534 rewriting
application.
•

If they are up to date, the procedure is complete.

•

If not, go to step 6.

6. Update the PGM-FI and TCM software using the i-HDS J2534 rewrite software with the MVCI or DST-i. Refer to
Service Bulletin 01-023, Updating Control Units/Modules.
7. Reset the throttle position learned values by referencing the throttle body removal and installation in the service
information, then do the PCM idle learn procedure. Refer to service information for additional instructions.
NOTE
For more information on the PCM idle learn procedure, see the Tech2Tech® video, "A Look at PCM Idle Learn".
SPARK PLUG INSPECTION PROCEDURE
1. In some cases, the DTCs may return. If this happens, inspect the spark plugs.

•

If the spark plugs are OK, the procedure is complete. Continue with normal troubleshooting.

•

If the spark plugs are fouled, go to step 2.

2. Replace the spark plugs per service information and check for stored DTCs.
NOTE
Make sure to write down the stored DTCs on the R.O.

REPAIR PROCEDURE B
If there is a whirling noise coming from the engine, follow the procedure below.
1. Warm up the engine by increasing the engine speed to 3,000 rpm for two fan cycles.
2. After the warm-up procedure is completed, let the car return to idle for 10 seconds.
3. After 10 seconds, slowly increase the engine speed up to 3500 rpm (this should take at least 20 seconds).
4. Once the engine speed reaches 3500 rpm, release the accelerator pedal and let the engine speed return to idle.
5. With the hood closed and inside the cabin, compare the audio file here to the noise heard.
•

If the noise is similar, continue to step 6.

•

If the noise is not similar, this bulletin does not apply. Continue with normal system troubleshooting.

6. Remove the cylinder head cover. See service information for additional instructions.
7. Compare the appearance of the camshaft lobes to the photo below.

•

If the camshafts appear similar to the no good photo, go to step 8.

below.

4. Raise the vehicle on a lift.
5. Remove the right front wheel and the engine undercover.
6. Remove the cam chain auto-tensioner (chain case) cover.
7. Slightly rotate the crankshaft counterclockwise to compress the auto-tensioner. Line up the hole in the lock and
auto-tensioner, then insert a 1.2 mm diameter lock pin.

8. Rotate the crankshaft clockwise back to TDC on the No. 1 cylinder to secure the lock pin in place.
