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:

Can't find it... not even mentioned in the BeCM docs.

Found this for you, ... any good?

Table

That's the ECU coolant sensor (2-pin), I'm after the gauge one (single pin).

I've only ever seen figures for the Ecu sensor.

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:

Thanks Blanco, hadn't figured it as the same as earlier models but that likely leads to a more informative section of the RAVE manual...

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:

Measured a new Bearmach AMR1425 sensors today. Also did AMR3321 and ERR2081 since they were handy. Posted here so they don't get lost again.

(First column is Temp in C, Second is Resistance in Ohms. Open in a text editor if you don't do spreadsheets.)
