Rated 5 out of 5 by from It works! Needed to replace my old sensor. Swapped it out and it works like it is suppose too. Its a pretty straight forward deal. Not much else to say. Highly recommended.

I'm looking for a short sweep water temp sender 29.5-450 ohm 1/8 npt. Will this work?

Asked by: Nagrom
This unit worked good for my meter.  Remember your gauge you are using need to match to the type of sender you need. So check on your gauge to see what sender you need, otherwise you will get the wrong temp reading.  This worked for me

Could I impose upon you to post a link that can show what sensors are used on AutoMeter electrical liquid temperature gauges? We use quite a few of your electric liquid temperature gauges on test equipment and need a sender-to-gauge P/N chart.

Asked by: Jake529
Thank you for your question. We do not have a comprehensive list, however, our current standard is that full sweep temperature gauges will use 2252, short sweep temperature gauges will use 2258, full sweep pressure gauges will use 2246 and short sweep pressure gauges will use 2242.

Hello, Can you please confirm that this sender is universal for metric and imperial short sweep gauges? Thank you

Asked by: Cusco
Thank you for your question. 2258 works with both imperial and metric gauges. The sending unit delivers resistance to the gauge, the gauge is then designed to show the appropriate reading for that resistance. A metric gauge would be designed to convert that resistance and show it in metric readings and an imperial gauge will do the same with imperial measurements.

What is the size of the nut on the wire end of the sensor?

Asked by: Nutty
Hi, thank you for the question. The thread size on the terminal end of 2258 the sender is 10-32 UNF-2A.

Do you sell just the 2258 sensor? I don't need the brass fittings.

Asked by: toddhillse
I purchased that sending unit from Autometer but it came with the fitting adapters guessing that is the way it comes

I have tpi tech gauges and looking for replacement temp sensor. I have bought one from you but it reads 50 degrees cooler than it should. unfortunately I do not remember the model I bought. can you help

Asked by: 1950 chvy
Hi there, thank you for reaching out to us. TPI-Tech is actually a different company and it's unlikely that our sender resistance range will match what your gauge requires. In addition to the 2258 sender, we also offer a 2253 sender that may be closer, but there is still no way for us to make any recommendation without knowing the resistance range your gauge requires.

I have the Autometer Water temperature gauge in a 1968 Mustang, 351W engine. The current temp sender makes the guage "start" at approx 220F when the engine is turned on. As the motor warms up it reaches 250F. What sending unit do I need?

Asked by: MENNO
Thank you so much for contacting us. First off, make sure you're using the AutoMeter temp sender that came with the gauge. It is not compatible with any OEM sending units. Secondly, if a temp gauge like this is reading high, it's almost always due to an insufficient ground. Make sure the gauge is grounded to either the engine or to a frame rail, and that the gauge ground is not shared with the ground for the gauge lights (we separate them out intentionally). If you'd like a more in depth take, check out this article we wrote on temp gauges: Hope this helps!

what resistance reading should I get at 15 degrees C from a E21792. -27 sender?

Asked by: irish
Thank you so much for contacting us. That particular is technically rated to operate optimially between 100 and 340 degrees F (38 - 171 C). There is not a spec for temps outside of that range published. You can see all of the sender specs here: As a general rule of thumb, if you're seeing temp gauge read low, you probably have resistance to ground on the sender side (teflon tape, etc can cause this). If the gauge reads high, you most likely have an inadequate ground on the gauge (we recommend an engine or chassis ground and keeping the lighting and gauge grounds separate).
