    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    Thanks for your answer. I used the same tool as you. But unfortunately, this tool didn't work. It wasn't until I bought the Autel TS508 Maxitpms that I was able to wake up all the sensors and then save them via OBD2. I think the Schrader 21507 are absolutely worth the money. Because I often...

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    Like I said, Amazon isn't always reliable. Contrary to the information from Amazon, the Schrader 21507 are perfect for my vehicle. You just can't easily teach them with the China Tester. I used the ****-TPMS TS508 for this. They had to be woken up and the ID#S saved into the ECU via OBD. All...

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    Hello dear friends here in the forum. Today I can share with you my solution to my Schrader 21507 sensor problem. I bought the MAXITPMS programming device TS508 from Autel. Apparently my sensors 1. weren't awaked and 2. The ID wasn't stored in the ECU. With this device, it was super easy...

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    I have been advised by many users that Schrader TPMS sensors are better than the cheap ones from Amazon and eBay, which is why I bought 8 sensors to replace my winter and summer tires. When ordering, I checked very carefully whether they were approved for my vehicle, I looked at the year of...

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    That's also the reason why I registered here in this forum, because I get great information and help from you and from you too, so that I don't make any mistakes and I also really enjoy exchanging ideas, because in Germany the US car forum isn't quite as big as it is here and that's why I'm...

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    Unfortunately, I order from Germany and have to rely a lot on the specifications here. Amazon is not the place where I like to buy spare parts. Especially since many fakes are sold. I have now sent a message directly to Schrader asking for clarification. Because somehow you have to be able to...

    Amzon is not a reliable source when it comes to defining cars. I was on the website of TPMS.com and there is my Tahoe listed. See pictures

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    As I answered above, I have this tool lying around in the car. I also put in new batteries. No matter where I put the nose of the tool down, I don't get a honk signal. Not even when I deflate the tire. ‍♂️

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    I tried the sensors with the same tester as you described to me. Nothing works. I also pressed the relearn button and deflated. That didn't work either. ‍♂️

    I cannot learn the Schrader 21507 TPMS sensor in the Tahoe 2007

    Hello dear community. I bought new TPMS sensors from Schrader model 21507 for my Tahoe through Rock Auto. In the past, I always had some cheap ones from Amazon or from China. Either the batteries were empty after 1 year, or, as is currently the case, the entire sensor unit was simply lying in...

    Dear all friends, I'll give you a short update because I found the mistake. As I had already written, the workshop (Cadillac and Chevrolet authorized workshop) replaced my airbag and simply removed the relay and did not put it back in again. When my Tahoe didn't start at all, I first had to...

    Urgent Need Help. DRL light and tail Light want work all other lights are fine..

    I was able to find a circuit diagram in my manual and marked the relay, the fuse and the continuing cables in red. I have a guess because when I was at the GM dealership, and they did the conversion they forgot to put the two relays STRTR and PWR/TRN back in place. My Tahoe just wouldn't start...

    @Doubeleive First of all I want to thank you for the tips. I have to inform you that 3 days ago I had a recall from GM US here in Germany, where the relay for the heater wiper water system had to be removed because, according to GM, there was a risk of fire and my passenger airbag was removed...

    Hello dear friends. I have a problem. I have noticed that my DRL and rear lights do not work when I turn on the light switch. The normal headlights, high beams, fog lights, front brake lights, turn signals and reverse gear lights all work fine. The only thing is that the DLR lights don't...

    Buying advice for brake discs for a Tahoe 2007 LTZ. Are performance brake discs absolutely necessary?

    Hello dear friends. I wanted to ask you which brake discs you use on your Tahoe's. I could order from Rockauto, but I have to pay more than 120 euros for shipping. So I have to look around Germany. Now I have the option of buying normal ventilated or slotted brake discs. Unfortunately, the...

    Tahoe 2007 LTZ 2WD 5.3 Transmission drips between the transmission housing and the engine block. Which seals do I need

    Hello @Geotrash, I have now checked the number on GM Parts Giant and it turned out that it is not the correct number for my Tahoe; the number GM 24202535 is given to me as the correct component. Have you possibly confused 2WD with 4WD here?

    Thanks @Geotrash for your answer. It is not Engine oil because, engine ist totally dry. It is a red oil and if you smell on it it is transmission fluid. Thank you for your help. The bushing that I have to replace I think I have to remove the front cover and push the bushing out. Because...

    Hello dear friends, As I already wrote in the headline, my gearbox (Tahoe 2007 LTZ) is dripping directly at the connection between the gearbox housing and the engine block.

    Thanks for the information. I was change them I think 40000 km ago. As I'm answering before, I will first order new spark plugs and for safety also a full set of wires. So i think in case I Drive with LPG maybe a spark plug had a defective. But it is not that you feel it hard. It is only a light...

    I am with you. I think I have to test first others before spending the money. I will see why it is only at the wet weather condition. It is not a ruff riding only you feel that he will not run as smooth as in the morning. Because at night he stays in a warm, dry garage. I will check first with...
