Marsflex TPMS Sensor 42607-33021 Compatible for Toyota Lexus Scion Pontiac, Tire Pressure Monitoring Sensors for Camry Prius Corolla rav4 Scion Yaris Replaces 42607-33011 PMV-107J 315MHz Set of 4

I've had great luck with these sensors I have replaced all the sensors in my 2005 tundra and my 2010 Camry they work great. I saved a bunch of money too!

These installed well on my 2012 Lexus IS 250. When logging the new sensors with the 2025 Launch Creader Elite, I ran into a trouble code on the Creader Elite. It said “ID registration failed due to a communication error with the ECU while in initialization mode. Terminate initialization by connecting TC and CG of the DLC3 for 30 seconds.” I had to contact AI for an interpretation and it told me "The TPMS ECU got stuck in initialization mode and isn’t responding properly. To reset it, you need to manually short two diagnostic pins — TC and CG — in the DLC3 connector (your OBDII port)." Here are the instructions: How to Terminate Initialization (Safely) 1. Locate the DLC3 Connector • It’s the same OBDII port under the dash where you plug in the Creader Elite. 2. Identify Pins TC and CG • Pin 4 = CG (Chassis Ground) • Pin 13 = TC (Test Connector) • These are numbered from left to right, top to bottom. • You may need a pinout diagram or flashlight to confirm. 3. Create a Jumper • Use a paperclip or jumper wire to connect Pin 4 to Pin 13. • Leave it connected for 30 seconds with ignition ON (engine off). 4. Remove Jumper and Retry • Disconnect the jumper. • Reconnect the Creader Elite. • Retry the TPMS ID registration process. Why This Happens • The TPMS ECU sometimes locks up during ID registration, especially with aftermarket tools. • Shorting TC and CG forces the ECU to exit initialization mode — it’s a safe, Toyota-approved reset method. I had to do the above "shorting method" twice, which was a chore for this fat boy to get down in the floor board to access the OBD2, and then plug the 4 new ID numbers into the Launch Creader Elite twice, but it all worked out. I hope all this helps someone else who has the same problem. Still a lot cheaper than paying garage over $500.00! Now lets pray the Marsflex batteries last at least 4 Years, if not, go with Denso. More expensive, but proven to last.

Really nice product everything works great I like it

Works well with my 2011 Toyota Prius Able to register them using AUTOPHIX 7360 OBD2 Scanner the TPMS warning lights went away after a little bit driving the next day

These work great on my 2007 Toyota Prius

UPDATE - seller reached out and sent 2 replacement sensors. Dealing with their customer support was a pleasure. Updated review to 5 stars. Sensors programmed fine to my 2016 4Runner but one is faulty and does not correctly read the tire pressure. It only reads 20 psi even though the tire has right at 35 psi. I have driven approximately 100 miles and it still is not functioning properly. I reached out to the Marsflex website customer support so we’ll see if they correct this issue. If the issue gets resolved I’ll update the listing otherwise be prepared to potentially receive a faulty sensor.

I liked that the sensors seemed like they were quality made, the valve stems seemed solid and the mechanic was able to mount/install them on my tires for around $100 labor. I don't like that after just over 2 months of being installed, the TPMS light is on again, and the mechanic showed me with his sensor that one of the 4 is no longer working. I guess I'll just by another set of 4 but only replace one at a time to save on the installation costs and keep 3 for spares and keep my fingers crossed. EDIT - after posting this review, I was contacted by the seller who offered to refund/replace the bad sensor, so I'll revise to 4 stars. The labor to have the sensor installed is more of a cost concern than the devices themselves. They do seem like a quality product (good sturdy metal valvestems, appears well assembled), so maybe I just got unlucky.

Had Sam’s Club install these - saved me a ton of money - they work, my tire pressure light is off now.

レクサスGS GRS191に無事接続出来ました。

Value for money good easy to program in the car

I have ordered these and have them installed. None of the scanners are detecting them after the installation. Going back and fourth with Amazon and the seller was waste of time as no resolution or exchange can be provided.

Los instalaron en mi Corolla 2011 y funcionaron bien. Espero que la duración sea buena. Gracias.

I had these installed on a 2008 Lexus RX350. They work great, without any programming issue.
