1. Does this disconnect the TPM's so they are not sending a signal thus increasing TPM battery life?


Also,
2. Will this method show up as a fault during vehicle annual inspection since the connector is unplugged?
1. No, because the sensors are inside each tire--they can't be disconnected.

2. No, because the resistor "fools" the computer so that the tire pressure looks correct.

Thanks for the prompt reply! So the sensors are transmitting a signal 24/7/365 even when vehicle is turn off?

They transmit every few minutes or when pinged or if there is a change, from what I understand. I could be wrong.

No and no.

If my TPMS light comes on apart from when starting my RAV4 and there is no actual pressure problem with the tires I will simply do as some others have done - place a small piece of black electrical tape on the dash instrument cover to blank it. Would be easy to remove if selling/trading in the vehicle - is getting more difficult for me to crawl under the dash nowadays!

Although the black tape thing may work for some, it's just too ghetto for me. I think the 3.3K 1/4 watt resistor is the answer when my sensors finally give up.

You're right, but you can always get used to anything. I had an old Maxima with a CEL lit for a couple of years with tape covering it. It didn't affect the engine itself so it still passed NY inspection. Until NY required no CEL, then had to get it fixed.

Wiring Differences



I noticed from the first post that the wiring was for a 2009. I was all set to do a 'switched" mod on my 2006 RAV but the wiring was not quite the same.
Pink is in pin 4, not 5​
Green is in pin 5​
Red is in pin 6​
Is the important wire the pink one?

As a stop-gap, I taped over the TPMS light.

Any advice would be appreciated.

Thanks!:thumbs_up:
I have a 2007 Rav4 and YES it is the Red & Pink wires even though their pin positions are different in the plug connector. I tested many configurations with a wire just to confirm. Works perfectly & the annoying light is gone immediately. Thank you to those who contributed to this post, cheers.
