Clois,

There are different ways the sensors operate, ones that have a single lead, generally require good contact with the unit they are mounted into or "grounded" to. These have a problem with teflon tape and some sealants. Literally, you can attach a wire from the sensor to ground and watch a change in meter readings.

The other type, used currently on several vehicles, have a two wire sensor and do NOT require the casing to be grounded. These are NOT affected by teflon tape.

If your sendor has two wires, you are prbably safe to use the tape. If it has a single wire connection, you will probably want to use a conductive sealant or ground wire.

As a last measure, you may want to check with the supplier.

Hope this helps.
