TPMS Problems

[Jonah52]

Hey there. My new to me 07 Denali is reading "Check left front pressure" and it won't go away. I checked the pressure of all 4 and the spare, just in case it had a sensor, and they are all good, but the code still comes up. What is the problem?

Probably a failed sensor. Very common issue. Sensors are cheap.

You could of course first try the relearning procedure. It's easy through the DIC controls.

I hate the relearning process through the DIC. I just bought on of these and it took me a total of 30 seconds from start to finish to reprogram the TPMS. Well worth the investment.

If the battery in the sensor fails I believe it does that too.

So most likely a sensor?

Yes. You do need to put it in TPMS learn mode and trigger all of the sensors to make sure it is indeed the LF. They may not be programmed to the correct location.

Like others have said most likely a bad sensor. Just but another OEM one-they are all over ebay. I've replaced 2 on mine already. I believe the sensors lifespan is 5-6 years but don't quote me on that. If you do the relearn procedure and don't get a honk at that wheel it is not communicating. You go from FL-FR-RR-RL. If you dont get honks at all 4 then you will see the message....

Had it tested while I was at work today. Tire manager said everything was working and all 4 were responding. I got in my car to go home and it still said left front. Do I need to try the relearn myself?

I would.

Give it a shot otherwise I'd get just one and replace that problem child......
