Anyone have a fuel rail temp sensor they can measure or know what the resistance range is on it? I would measure mine but it's burried too far in the back of the engine bay.

I'm looking for order of magnitude... is it 2k, or 20k, or 200k ohms at ambient or operating temp.

Thanks,

mhamilton,

I don't have an EFT to measure for you, but maybe the pinpoint tests for the engine fuel temperature sensor may provide some helpful information. I know there's a table of voltage readings vs. temperature. The tests begin at the bottom of page 2806 of the Powertrain section of the Workshop Manual, which can be downloaded from this forum at this link:

Thanks Don! Had never stumbled across that pinpoint test for the FTS. Actually reading a bit further down, it gives a pinpoint for the sensor itself. Apparently 500k ohms is the upper limit (coldest reading).

G549822t27 : CHECK THE COMPONENT RESISTANCE on page 2813. So that gives me some good info to go by. Thanks!
