Safety Recall: 3.5L V6 Timing Belt

Supersedes 19-045, dated April 12, 2019, to revise the information highlighted in yellow

 

AFFECTED VEHICLES

Year Model Trim VIN Range
2019 Odyssey ALL Check the iN VIN status for eligibility.
2018-19 Pilot ALL Check the iN VIN status for eligibility.
2019 Ridgeline ALL Check the iN VIN status for eligibility.

 

REVISION SUMMARY

  • Under REQUIRED MATERIALS, the Honda Genuine Motor Oil part number was updated.
  • Under INSPECTION, Step 5 was changed.

 

BACKGROUND

During production, a supplier produced some timing belts that do not meet specification. These timing belts may shred or slip, causing the cam shafts to fall out of timing. Camshafts that are out of timing will set DTC P0341: CMP Sensor and CKP Sensor Incorrect Phase Detected and/or DTC P0369: CMP Sensor Circuit Intermittent Interruption and the engine will run rough. Additionally, shredded timing belts may cause the vehicle to stall and not be able to restart, which increases the risk of a crash.

 

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

Inspect the timing belt and, if necessary, replace the timing belt. If the lot codes are not visible or the timing belt is damaged, a cylinder leak down test may be required and, based on those results, further repairs may be required.

NOTE

Only a small percentage of vehicles are expected to have timing belts that are out of specification. Only order replacement parts after you have identified an out-of-spec timing belt.

 

PARTS INFORMATION

NOTES

  • Parts are applicable to all models unless otherwise noted.
  • Only a small percentage of vehicles are expected to have timing belts that are out of specification. Only order replacement parts after you have identified an out-of-spec timing belt.
  • Order the engine block and the applicable cylinder head(s) after a damaged engine is identified by completing a cylinder leak-down test.

  1. Check the cam timing and do a cylinder leak down test.

NOTE

The following steps will determine if there was any valve to piston contact requiring the replacement of the cylinder block and one or both cylinder heads.

19.1 Remove all the spark plugs.

19.2 Do the cylinder leak down test. For information about the cylinder leak down test, refer to the following:

    • See the Online University Self-Study Module WAENC10 Pump Theory and Cylinder Performance Testing

NOTES

  • Rotate the engine only in a clockwise direction.
  • Confirm each cylinder is tested at TDC.
  • A good cylinder should have less than 10% cylinder leakage.

19.3 If the cylinder leak down test results show that all six cylinders have a leak down rate of 10% or less, go to step 20 and finish installing the timing belt.

19.4 If the cylinder leak down test results show that at least one cylinder has a leak down rate that is more than 10%, and the leak is from the intake or exhaust valves, replace the short block and the cylinder head(s) where the leak is coming from. Refer to the service information.

NOTE

If the leak is coming through the crankcase, this bulletin does not apply. Continue with normal troubleshooting.
