I've purchased 5 new TPMS sensors and my 2006 Tahoe only wants to talk to 3 of them. These new sensors are installed in Tahoe LTZ wheels. The strange part is that the scan tool read both of the 'bad' sensors when they weren't mounted in the tires. The first order contained 4 of the same part number, only 2 worked were readable with Discount Tire's scan tool and NTB was able to read the 3rd one. I ordered a replacement for the one that neither scan tool would read.
Here's the scoop from today's failure at NTB...this is all on 1 wheel:
Scan tool read the new sensor(uninstalled) right out of the box.
Scan tool read the new sensor that was removed from the wheel.
Scan tool will not read the whatever sensor is installed in the wheel.
Scan tool will read uninstalled sensor when the Tahoe is not in relarn mode.
Scan tool will not read either sensor when the Tahoe is in relearn mode.
Air pressure method was tried, again only 3 of the 4 sensors relearned.
Removed problematic left rear wheel and rolled up next to the left front wheel(weak reception maybe?), tried relearn again, no change in symptoms.
Changed the order of relearning the problematic wheel from last to first, no change in symptoms.
I left NTB, returned home, rolled one of my factory wheels up next to Tahoe, tried air pressure method.....I only got same 3 wheels to honk, but it seemed difficult to be successful with this method. It took several attempts to get it to respond, so I haven't ruled out trying this again with one of my factory wheels. I only had one sensor flaking out in my factory wheels and it would read about 75% of the time(Left Front was intermittent). The left rear seems to be the problem with the new wheels, but we tried to learn it as the left front and still had no luck.
This is crazy. Has anybody got any suggestions? Does anybody actually KNOW how the TPMS works. The best I could find is that it is likely the same antenna/receiver as the keyless entry. The keyless entry is working just fine. I've considered pulling the fuse to try to 'reboot' the receiver. Insanity.
