Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
Sanders, I think many of us got lost in the weeds with this haha. I don't think the tube is meant as a suggestion for you (I think it was a technicality on the function of TMPS sensors). I think the bypass module (little black box) is recommended to you as a possible way to mitigate the issue.
My suggestion to you is having a shop with a shop-level scan tool verify your tire pressure monitoring system (TPMS) is adjusted to "Load Range C" and "32 PSI". If anyone has changed this setting in your computer (out of good faith), it may be causing your issue.
Obviously you did not read all the information posted above. A pressure sensor converts pressure into an analogue electrical signal. ALL H3's requires 30-35psi to send the proper signal. However, I've tested, and can confirm minus -17% @35psi variance=warning.
With the simulator, the bcm always gets the proper signal tires set @35psi, regardless of the actual tire pressures psi. Bottom line, check your tires before you drive!
TPMS is on hold for a bit. I'm on to the 02 sensors now. Got 3 out fairly easy. The one on drivers side in front is giving me problems. I sprayed with Kroil and tap. Will do this about 4 times today. Try in morning . ? now is can I put a little anti-seize grease on new ones? I will spray the connections with electronic spray. Heat maybe cook the grease? Things to ponder.
I've used Kroil many times and it always works. Spray and tap. Don't get in a hurry. Yesterday I sprayed and tapped 4 times on the drivers side forward. This morning I put the 02 socket on and out she came with very little effort . Waiting for my new 02 sensors to arrive. They will be installed with the copper anti-seize . I put the old ones in brake cleaner fluid. Tomorrow I'll finish cleaning them. Pack them away, Why? I don't know. I do dumb things to entertain my self. However some time ago I took them out of my Lexus RX 300. Cleaned them. Reinstalled and worked great.
brake cleaner can damage them. the safest way is to just burn the tips clean on the stove or with a torch. it will remove the unburnt fuel caking them/ (black soot)
Burning the tips doesn't clean the element. Best way, perform an induction clean while they are installed. Uninstalled, torch/heat up the the tips and dunk them in water, or heat up the tips and clean with crc.
