Well, honey, to fix that DTC code C2126 on your Toyota Tundra, you'll need to check the tire pressure monitoring system (TPMS) sensors and make sure they are all functioning properly. If they're all good, then you might have a faulty TPMS receiver or a wiring issue causing the problem. Get that checked out by a mechanic who knows their stuff, and you'll be back on the road in no time.
