I have an 07 endeavor SE with 90k miles. Recently my tire air pressure light starting flashing indicating one of my valve stems pressure sensors is bad so I thought. But it comes on sometimes but not always. Then 2 days later now my radio makes a humming noise when on (whether in cd or radio). Then today my tcl light came on even though I didn't hit the tcl button. When I turned off the car and turned it back on it did not come back on again.

Anyone else had any of these issues? I starting to think that maybe there's an electrical problem or something?

 

Well it doesn't appear to be an electrical issue causing these issues. I hooked up a Snap On computer and the TPMS light was on due to wheels 1 and 4 having low voltage from the sensors batteries dying. The traction control light wasn't throwing a code so haven't figured that out yet but I'm being told it's probably a bad sensor causin it. Haven't figure out the humming noise yet but I suspect it may either be a bad ground wire somewhere or the factory installed amp is going bad.

$130 and both sensors were replaced today.

 

totally worth it.

 

Called around to several different tire shop, they all wanted between $85-$95 per sensor plus $20-$30 to install each sensor. Shopped around and found the sensors for $39 each at NAPA and PepBoys installed them both for $49 !

Now to figure out the traction control sensor ....
