SUBJECT:
Seal on 2 and 3 Pin Plug Connectors
MODELS:
All
Situation:
When connecting or disconnecting 2 or 3 pin plug connectors (for example, on the injection valve, throttle valve potentiometer, or engine coolant temperature sensor), it is possible for the rectangular seal to fall out of the plug housing. If this should occur, the loss of the seal can easily go unnoticed.
As well as preventing moisture from seeping into the plug, the seal also ensures that the two halves of the plug are properly tensioned so that the contacts do not move within the plug. If such movement should occur, the contacts may develop corrosion.
Corroded and/or loose contacts can cause problems with the proper functioning of the vehicle, and may cause difficulty in diagnosis due to the possibly intermittent nature of such problems.
Affected Vehicles:
All models
Procedure:
It is essential that you check that the seal is in place before connecting a 2 or 3 pin plug connector. If the seal is missing, it must be replaced.
