TPMS Sensor Programming Help, MaxiTPMS Tool

Maintenance/Repairs

I have a 2014 Acura TSX and am having difficulty programming the new sensor.

The new sensor I got is a STANDARD MOTOR PRODUCTS TPM1A

I’m trying to program it with an Autel MaxiTPMS TS508

This brings up the information for the current sensors on my car, I select the sensor I want to copy the ID from to the new sensor, and then get to the screen where it’s supposed to program the new sensor, and I get a “No sensor detected (-2)” error

so I thought that perhaps the new sensor I got was dead upon arrival.

I tested this out by doing
Quick Mode → Acura → TSX → 01 /2009-12/2014(315MHz) → 2 Scan Single Sensor → Pressed the Y Button →

It lists the correct sensor ID that is on the new sensor, and says it has a good battery.

I’m not really sure what I’m doing wrong. I can’t seem to program the sensor with my tool, but my tool can detect that the new sensor is there.

Thanks for any help!

New sensors are sometimes in sleep mode until there is a pressure change greater that 6 psi.

Hey thanks. That would make sense, to save battery. Is there anyway to expose it to that pressure without installing it in the tire?

Why would you not install it? On my Acura they reset by driving over 15 mph, but maybe the tire shop initializes them first. Don’t know.

You bought sensors and a tpms tool. Vs having shop put them in? Wouldn’t it have cost the same? Then ur done.

Are you going to install it in the tire yourself???

I presume OP is attempting to test the sensors before installing them, just to make sure they work. Makes sense. To do this it appears OP may have to put the sensors in a pressurized environment to get them to wake up. I wonder if something like one of those pump-up garden-sprayer gadgets might work? Google ‘one gallon pump garden sprayer’ for example. Another idea, maybe a discarded bicycle tube. Cut if off 3 inches from the valve on both sides, put sensor in, and figure out a way to clamp both ends air-tight, pump it up.

Or simply go to a tire shop like most of us do. Some things require innovation, others just common sense.

A test chamber can be made using pvc pipe, @davesmopar has a picture of one.

OTOH, it takes 3 minutes to install the sensor in a tire/wheel, it will end up there anyway.

Indeed. I’m looking for a way to test to make sure that I have a good sensor and that I can program it before it’s installed. I was going to have a shop install it for me, after I verified that it was a good sensor and I could program it.

I’m surprised a product doesn’t exist that can expose it to a few PSI before installing it. I tried a few chemical bug sprayers, but the TPMS sensor was to big to fit in the hole of the chemical sprayer.

I googled a pressure chamber, or pressure chamber, and way to expensive for just testing a TPMS sensor.

I think I may just have a shop install it and gamble that it’s a good sensor. At least I’m able to verify that the battery is good. Thanks that I didn’t know they were in “sleep” mode to preserve battery, but it makes sense.

If you have a wheel barrel/tire then break it down and throw the sensor inside of it, or lawn mower tire or whatever… Just try to think outside the box… Then air it up to test…
Not that hard to find something… Worst case just have the shop either test it for you or see if they will just throw it inside your spare or a used wheel tire they have laying around to test it… The sensor does not have to be mounted to anything, just has to be in some kind of pressure chamber… Again, think outside the box…
