Shop Discount TPMS Sensors

2009 Chevy Impala LTZ 3.9 V-6 with 64,000 miles. also, I just purchased a new battery 3 months ago. had the starter, alternator, and battery checked and they all came back good after the 1,000 mile drive back home from Florida. While we were there the car sat a few days and it was completely dead, no light left on or anything plugged in. jumped it and a couple days later completely dead again. We did have new tires put on right before we left and I believe they ruined the TPMS sensors even though tires plus denies it. they worked fine until they put on new tires. would the tpms sensors be looking for a signal and that's why the battery is draining? any advice would help, thank u

No, that's not your battery drain problem. You need to start out by testing the battery and charging system.

Had the starter, battery, and alternator all checked, autozone says they all passed and are working good. am I forgetting something else?

Then you need to test for a parasitic draw.

There is a procedure for finding a battery draw like that.

You will need a digital ammeter and a jumper wire with clips on the ends to do this.
First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 10 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated.

thanks for the info. i'll give it a shot. I have to purchase a digital ammeter since I do not own one of these, where is a good place to buy this and how much?

A real high grade one is a couple hundred but you can get much cheaper ones online or at a parts store like Autozone. They have some down in the $30-$40 range.

hi guys a couple months ago one of my TPMS sensors broke off and my tire pressure light has been on my dash ever since. I was wondering will my car pass New York state inspection with this light on thanks for your help. It is an 08 dodge magnum

I'm not familiar with NY state inspection guidelines. All I can tell you is that is a safety system that is malfunctioning. If I had to guess I would say that it wouldn't pass.

Most sensors are around $100 give or take plus with it was working properly you would know if you had a tire pressure problem....

Laugh - I found a site that specifies what will or won't reject your car and tire pressure was NOT listed for NY.

">>
Tires
(Except spare)

Going off that info it looks like it should pass. (or at least not fail due to the TPMS light on)

I even looked for an "any warning light" on clause and didn't see any. The only warning light it looks like they are concerned with is the SES.

I would have thought MA and CA would be the toughest but it still varies state by state. Here, at last check you can fail for inoperative windshield washers even if it's just out of fluid! In Maine you can fail if tires aren't speed rated for that specific car even if new!

MA any car must pass the safety checks - basics. ABS light on won't fail you. 96 (OBDII) and up must connect or it's a fail! They no longer check emissions here pre OBDII unless it's billowing smoke or something.

Speaking for here they change the rules constantly! I like the idea of the tire pressure warning light BUT you can buy a set of tire caps that tell you the pressure by color for $5 bucks - just do a walk around and look. I can't speak for every place as it changes so much. They do NOT pull wheels off here as too many weren't tightened right or hurt VERY expensive wheels so that ended that. They still better feel ok as they do take the car from you to check it.

This stuff is still very specific to each state. That site if up to date seems like it's helpful to know current regulations and rules for a legit inspection sticker............

Hi! I have a 2004 Chevy Tracker. Umm, not sure of engine size? I know its a V6. Has about 120k miles on it.

In May or June I got a flat tire. It started going flat gradually so we just added air but then one morning it was just completely flat. We added some fix-a-flat and took the tire to have it patched but they couldn't find the hole. It drove fine for a week or so but it continued to lose air slowly so we bought another product similar to the fix-a-flat. This product was supposed to be more permanent. It required that we take out the valve stem to completely deflate it, then pump this stuff in, replace the valve, and re-air.

The next day when I drove to work I noticed that when I got up to about 60-65 my car would shake. The shaking seemed to move across the car. I would feel it first on the drivers side and it would vibrate across to the passenger side. So I had the tire replaced thinking that it was just beyond repair.

This did not fix the problem. A couple of days later I had the tires rotated and balanced. Still didn't fix the problem. I have not gotten an alignment but I've done the test of letting go of the steering wheel to see if it pulls to one side and it stays pretty much straight.

A couple of weeks ago I had another flat tire. This one completely blew out so I thought maybe it had been the problem. But no, it wasn't. It was actually my replacement tire so I guess it couldn't have been the problem since it wasn't there originally. That part is probably completely irrelevant but just in case I added it.

Anyway, the past couple of days the shaking has gotten worse. It starts shaking around 55, sometimes lower and just gets significantly worse as I go up. Any ideas??

It kind of strange that this all started right after you put that stuff in the tire. What was the name of the permanent garbage you put in the tire. Maybe that stuff hardened to the rim and the tire changers didn't bother trying to scrape it off. If they could even scrape it off.

By the way tire techs hate when customers put fix a flat in tires. The stuff also screws up TPMS sensors FYI.
