Help! New TPMS reads 1 psi after install
 

Hello all. Sorry if this topic has been covered, but I am having trouble with the tpms. The car is a 07 TL type s and I was wondering if there is a relearn procedure. I called Acura and they want to charge a minimum of $200 just to check the problem and maybe fix the issue by reprogramming the sensor. Please if anyone can help and sorry once again if this was covered.

P.s. I bought the replacement part at rockauto and it says to follow same relearn procedure as oem but no instructions.

OEM unit relearn procedure is super simple, mount the new unit and boom... it register with the car. since you bought the no name one from Rockauto I am not sure how they can even program it.

Thank you for the reply. I just came back from a drive and it read for a while at the wrong psi then the system wiped out, like didn't display any psi to any tires. This was the same symptoms the original had. I wonder if it's possible the receiver went bad and not the sensor.

Its not the receiver, next time when you 1st start the car up, goes through the menu where they display individual wheel pressure. You will see any abnormal sensor.

The same thing happened with the old sensor that's why I thought it was bad. So I had my tires replaced shortly after driving had the code for the sensor. It would read erratic psi like 60 psi when only being at 34 psi. After having a reading it wiped out the system then cycle all over again. This is why I replace the sensor.

Just as an FYI I purchased 4 of these last December when I replaced my tires for the first time on my '08 TL. https://shop.advanceautoparts.com/p/...981/16970019-P

had 10 years on the originals so figured I'd change them all with the new tires. They all showed 0 psi when starting and driving the car and literally within 30 seconds all 4 popped up with the tire pressure at once. Nothing was done by the Honda dealer where I got the new tires put on as they specifically asked me, when they were at that point, if I wanted them to program them and I said don't do a thing from what I read they'll show up automatically.

ETA: at the time they were installed all were 2 psi off but on their own they're all on the money to the correct psi now.

Go to discount tire! They have tools in order to relearn the individual sensors and link it back to the ECU. Although, if the sensor is inadequate for the vehicle, you may have to buy a new sensor. They sell them too, and will program them. But you're right, if it is not the sensor, and relearning is futile, then the ECU may be improperly conveying signals and that sounds like a problem you'd need to see a dealer or Acura mech about.
