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

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.

Installed on 2010 Prius by a tire shop. The cars has a Tpms reset, used Google to find the correct sequence and dash error light gone. Hopefully they last more than 5+ years. Will order another set for the 2007 Prius. Thank you

Put these in my 2011 camry se and my friend programmed them with his tool and they work perfectly. If they leak then you need to tighten the core with a core tool..

Two wouldn’t program and it cost me a lot of money. The tire shop, who I’ve used many times without issue spent hours trying and trying to get them to take a program to no avail, so I had to buy a set from them to get them to work. I know cars and how tpms scanners work and they showed me. They weren’t trying to milk me, these legit wouldn’t work. So they had the car a whole day, charged me the labor at $189/hr and then for another set of sensors. On top of the tires, the mount/balance and the nonsense with the tpms, it was an expensive day! They’re cheap parts, until they’re not.

The sensors work, but make sure that your valve stems are tightened. I see, they slightly lose air. If you don't take that step

Good product connected to my car was easy with scanner the tire shop had

Perfectly worked for my Prius. Also before I purchase these, I saw few comments saying that these don't work if installed at Walmart so they went out to fix them. But I got it done by Walmart. And Will update after a while or if something changes.

Perfect fit for 3rd gen Toyota Prius (2010-2015). The OEM retaining nut is 11mm, these are 12mm. The sensors may be a tad bigger than OEM, but the difference is negligible. If for any reason you strip the new retaining nut, the old one will fit this sensor as well. Relearning was easy because it was already programmed, just scan and connect it to your OBD2 and it’ll rewrite the ECU. Took a second for the scanner to read the sensors, but just move the reader a round the stem and it’ll pick it up.

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.

ちゃんと使える

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.
