Marsflex TPMS Sensor Compatible for Jeep Grand Cherokee Dodge Ram 1500 Chrysler Fiat, Tire Pressure Monitoring System Replaces# 56029398AA, 56029398AB, 68241067AA, 68241067AB 433MHz

With the proper tools these sensors are easy to install. I have a Harbor Freight manual tire changer in my garage (doesn't everybody....?) and using that to break and hold the top bead down I used a valve stem installation tool to first break off the old stem and then remove the old sensor. Installing the new sensor, there is just enough clearance to get the new sensor/valve stem assembly into the wheel and then pull up and seat the valve stem with the stem tool.I then drove the van and in about a mile the system recognized the new sensor and the tire light went out.I can't ask for anything more. These Marsflex sensors (only needed one so far) work perfectly. I will probably use the other sensors in the not too distant future as the batteries in the original Dodge sensors wear out. I like to get every last mile out of my car parts!Update: So far I have installed 3 of these Marsflex sensors. They all work fine. The car's tire system recognized the new sensors within about a mile or two of driving and the tire light went out, I didn't have to do anything special.

3 of the 4 synced with no additional equipment needed. One of the 4 did not register at allEdit; The seller sent me another sensor to replace the one that didn't register. All 4 working now with no problems

This product is absolute JUNK! They do not show actual tire pressure readings. All 4 monitors always show 34psi, even after driving 50 miles on a hot day. The product is potentially dangerous. You could have low tire pressure & not be aware, thereby contributing to an accident. Advertising is deceptive, looks like they have some sort of pre-programmed numbers.Tire pressure should vary as the rubber heats up or cools down. These monitors display static tire pressure readings, with all 4 being identical. This is not the way tire pressure readings work. If it were just one then I would think the individual item was defective. But ALL FOUR NEVER change, regardless of whether my tires are hot or cold. This suggests that they're designed to be deceptive. It cost me money to have them installed & will cost money to be swapped out. PLUS I will be out the cost of buying these in the first place. I have been utterly swindled! COMPLETE GARBAGE!

Update: after 6 months, they’re still working perfectly fine. I’ve had zero issues with these and they respond fast to pressure changes. When the temp dropped, the light came on and I could see that all my tires were low. Went to the tire store for more air. Not even 1 minute of driving and they responded with the new pressures in the screen. Very pleased so far!I had Discount Tire install these for about $60. They self-learned in about 10-15 minutes of driving. Hopefully, they'll last. But for now, it fixed my TPMS error and I could see some of the pressures dropping off here and there on the info center. Now all of the tires are showing correct pressures. I had one shop quote me $40 per sensor plus install. Worth the money and risk to buy on Amazon and see how long they'll last.

They fit my 2014 jeep wrangler and no error lights. what more could I ask for

Works

Had to replace all my sensors. Two were completely out and the other two were reading that they were for the front tires and they were actually in the back. I purchased this set based on other reviews and they didn’t disappoint! Easy to install and they synced up to my car after a few miles! Love the price point as the local auto parts store wanted $90 for one. They’re working great!!! I would definitely recommend this set of sensors and would purchase them again!!

These worked without a problem after installation. I just had to drive three or four miles. But after 13 months, one of them has quit working.
