I know that the TPMS manufacture number must be 42607-33021 in order to work on our IS.. So i bought a set from ebay seller:
http://cgi.ebay.com/ebaymotors/ws/eB...id=p2759.l1259
The listing specifically noted the manufacture code is 42607-33021

However, I recieved all four today but none of the code on the sensors matches.
Here are the codes on the front of each sensors.
1st sensor:
0831712561
5BA53A1

2nd sensor:
0831711861
DAC13A1

3rd sensor:
0831711561
051A3A1

4th sensor:
0831711561
299A3A1

All four sensors FCC ID: PAXPMV107J

Are they suppose to be like this? Thanks!

 

Yes the codes are supposed to be like this but are you sure you picked the right part number sensors? For my 06 IS250 AWD its 42607-33030. For 08+ (I think) the part number is different

 

ok thats good than.. Yea i'm sure I got the right manufacture number, cause mine is 07 AWD, and its 42607-33021. Thanks for clearing that up

 

i bought one set of sensors from the same guy who is selling them. works perfectly.

car produced up until mid 06 uses a different sensor.

all other models of mid 06+ uses those sensors. almost every toyota/lexus uses those sensors.

 

Looks good. I think the most important is the FCC ID: PAXPMV107J.
