TPMS troubleshooting
Hi everyone... '09 Carrera 2..
Long story but the TPMS is not working.... I have tried 2 different sets of aftermarket sensors, and bought a used TPMS computer. It didn't fix the problem(s).
PIWIS Codes when I checked were
8003 – Control unit faulty / internal error or communication error with the TPMS control module.
8022 – No signal from left front wheel sensor.
8023 – No signal from right front wheel sensor.
8024 – No signal from rear axle sensors.
Gave up took it to the local dealership...finally got to the car a few days ago...basically I was told by the mechanic that the solution that was most likely to fix the problem was replace the 4 TPMS sensors with Porsche ones and get a new TPMS computer. And if I didn't want to do that, just unplug the TPMS computer and deprogram the instrument cluster so the TPMS doesn't show up anymore.
I told the service advisor that I didn't want to told the "the TPMS isn't working"...which is what they basically told me.
So spend $1200-$1400 CDN with doubtful probablilty that it's going to fix it or just get rid of the system..
I would have thought a dealership could investigate it to a more granular level...ie checking the antennae in the wheel wells, any wires connecting the antennae to the TPMS computer etc....that doesn't seem to be part of their repetoire...
Do I have unrealistic expectations??
Any suggestions for trouble shooting??
thanks...Paul

On a related issue, of course the mechanic asked if they were Porsche TPMS sensors..."I said no, should that make a difference?" He said well we might have trouble programming them etc etc...
Do TPMS sensors need to be "programmed"? I understood that if they were the correct frequency the car antennae would automatically pick up the signals after a short drive...
Can anyone shed some definitive information on this process please?

I changed all the TPMS last summer on my 2011 C2S as the batteries were starting to die. Got them at Tire Rack (OEM) and had them
installed at Discount Tire, now a partner of Tire Rack. Reasonable prices and great service. Within about 5 miles they were all functioning.
I did have an incident a while back when, after a routine check with my Durametric, I noticed some codes for the left front module,
the bulb in the frunk which I changed to LED, and some others including the TPMS. I put the original bulb back in and voila, no more codes.
Those modules must be extremely sensitive. Thankfully I didn't start replacing all the electrical components in the front.
The other thing that I am concerned about is mice chewing on the wiring. Best of luck.

I was told by a seller of TPMS sensors about 10yrs ago that the 997.1 don't always play well with aftermarket sensors and he suggested to only use Huf sensors (OEM sensor). Not sure if this applies to 997.2.
That is what I did 10yrs ago and order another set of sensors for a tire swap this spring.
I bough Huf sensors from from TPMSbargains.com
https://www.tpmsbargains.com/Huf-Int...8-997-hufm.htm
for 997.2 it would be the following

The only "programming" I did was to drive around my neighborhood and respond to the prompts from the on-board computer that were displayed on the instrument cluster. Very simple process and they have been working fine since 2018.

Not surprised by the dealership’s suggestions. All they are trained to do is replace with factory parts with little or no troubleshooting. Aftermarket sensors are fine if they have the correct frequency which is 433 MHz for 997.2. Any reputable tire store can test the TPMS sensors batteries and signal strength so at least you can confirm they are working.
Try changing the TPMS settings for tire type (winter or summer) and tire size (18” or 19”) using the control lever on left side of steering column then do a TMPS reset. Doing this reset has worked to fix TPMS faults for others on this forum.

I had Discount Tire replace the 2 fronts on the 997.1, in and out in about 2 hours. It took a bit of driving for the car's computer to recognize them but no problem after about 25 miles. I had earlier replaced the 2 rears with Huf transmitters when I had new Michelins put on, but the fronts being dead wouldn't allow the system to work. All good now. Way cheaper than going to the dealer.o
