wtf. A low tire pressue light on an '07 ranger?

dougs3.0L98 · Nov 6, 2007

hey everybody! my friend has a 2007 ranger 4.0L Fx4 5-speed.

Before tonight we just figured the drivetrain was the same as my 98 ranger.

Untill a light came on in his dash beside the fog light indecator light. He looked in his manual and the warning light is for "low tire pressure"

When did rangers start having this?

What sensor is doing whatever to tell this???????

an ABS or speed sensor?

me and my buddy are real confused. we're not sure if we even like this little light, what about when we air down for wheeling? i guess we will expect the light to come on?

Check your tire pressures. Drive around and it should reset. If not, you're in need of a trip to the dealer.

Oh, goody....just what we needed. More electronics....

Totally done to save Ford's ass.

Most cars, trucks, and SUVs have this standard today, if not at least an option. Fill up the tires to the manufacturer's specs, drive for 2 minutes afterwards, and the light will reset itself.

IIRC, it is now required that new vehicles have this idiot light. Seems most people don't seem to notice when their car is leaning adnormally to one side.

But then again, If I had a penny for everytime I pass a car on the interstate and see a christmas tree of trouble lights lit on their dash, I would be retired by now.

Nice to have, but no one will notice, and out of those who do, most will ignore it.

The real crack up is how some systems detect a tire pressure differential...

The ABS system is "smart" enough to detect that one wheel is turning at
a different speed than the others and it can tell that you aren't in a turn.

I thought that was how ALL systems detected it?

there a little sensor behind the tire its connected to the valve stem, it tells ur comp what the pressure is in each tire, if u rotate tires or one is low u have to reset the sensors, by lowering the pressure all the way till the horn blows, and u have to do this for each tire, thats how it is on gms, not sure how it is on fords, glad im not changin tires any more, thats was a pain.

Yeah I've changed a few tires on cars with those. They're pretty spendy if you break em. Oops....

Classic GM, reminds me of how you reset the "Change Engine Oil" indicator.

The first time I tried, I didn't know you were supposed to floor it 3 times with the engine off.. Oops, there went a quarter tank. :blush:

From what I have been reading, this is now mandatory equiptment on vehicles as of 2007 I believe, or for 2008, I can't remember. Most systems work by a sensor mounted to the inside of the rim on the valve stem. For rotating tires, GM has the lower tire pressure until the horn blows, Chrysler has a Magnet sensor that you have to hold over the sensor in the wheel until the horn blows, and I have yet to run into a Ford with this yet. I know Mitsubushi (also some Chryslers built buy Mitsu) the sensors are "generic" and will automatically set without a procedure, at least on the few I've done.

I think this is going to be one of those features where I'll tear the dash apart, and pull the bulb, like what I did with my ABS light, since it stayed on when I pulled the relay. I find some of the sensors on some vehicles too picky, where if you parked in a parking stall, and 2 tires were in direct sunlight, or in a hot location, and the other two were in a cooler location, it would/could also set the light off, I've seen this problem constant with Montero's (spelling?). Like what was said, this Idiot light is just another light for people to ignore, and just one more thing to go wrong costing you big bucks in the end. Some sensors start at $500+ per sensor, some are cheap at $40.

Most Ford sensers are held on by a band that goes around the rim, 180 degrees from the valve stem.
