P38 V8 Coolant Gauge Sender Ohms/Temp

Recommended Posts

Does anyone have the resistance measurements (Ohms / temperature) of the GAUGE sender (not the ECT for the ECU) for early P38's?

I was sure it was in the RAVE manual or something but jiggered if I can find it :huh:

Forgive a mere mortal wot hasn't had a V8 now for many a long year.........:huh:

Apparently Rave does reference it somewhere:... saw a reference to section 19 somewhere?

In the Rave manual, it shows a picture of two engine coolant temperature sensors, but in the description, it just talks about one (my guess it is talking about the one with the single bullet connector. It says it should measure 28k ohms at -30 degrees C, 300 ohms at 85 degrees C, and 90 ohms at 130 degrees C.

What is the other sensor for (the one with a two prong connector)?

Found the above comment Here

Also found This and This too, on the basis that the sindle pin sensor is AMR1425, 'green' which I think is correct.:unsure:

Hmm, I cut and pasted the above from my notes files, I should have read it first - I have a second file in my archive with numbers that much more closely match the aulro link that Blanco posted.

As a penance, tomorrow I will put the kettle on and measure one....again, and this time I'll try not to lose the test data :rolleyes:

Just for completeness, added ETC8496 to the list. This might be a useful one for someone, as it's very close to AMR3321 in performance, but packaged like ERR2081, so fits the sensor boss hole in the middle of the 300tdi head. Might be a useful conversion part for someone?
