Issue:
Cleaning the throttle body will wash contaminants into the bearings, and will remove the grease from the throttle body that is necessary to ensure its
correct operation. Either of these actions can reduce the life of the component and result in the subsequent failure of the throttle body.
The electrical connectors on the throttle body must not have any types of grease (including dielectric greases), oils, or sealants (including silicone)
applied to help seal the connectors. Applying these products can result in corrosion of the connectors and result in failure of the connector.
Action:
Do not clean the throttle body.
Do not apply any greases to the electrical connectors on the throttle body.
When reinstalling a throttle body, it is important to ensure that all connector seals and wiring seals are in place and are not damaged. Verify that all
connectors are fully pushed home and latched correctly.
Note:
If a throttle body is replaced under Warranty, and is found to have been cleaned, or if oil/grease or sealant have been applied to the connectors, the
Warranty claim could be rejected if this is found to be a contributing factor to the failure.
