Might be there to dampen the sensors response.
ie be there to cover for not enough filtering in the code, and resultant =
timing/fuel corrections, that result in a lack of smoothness in the way =
the engine runs.

Subject: [Diy_efi] coolant temperature sensor extension (?!)
I pulled out my coolant sensor while working to replace my water pump =
and thermostat.
Strange (?), the sensor is mounted in an extension. The aluminum =
extension has what looks to be a sensor on the end of it. When I =
seperated the two, the actual sensor looks normal except for what looks =
like a little lithium grease inside the extension where the actual =
sensor resides.
What's odd, is that the threads on the extension are the same size =
threads on the sensor.
Why would this combination exist? Am I missing something, here?
Can I dump the extension and just put only the sensor back in the =
block?
Does anyone have any incite into this combination/situation?
Thanks,
Bob
