Went to my dealer because my LF sensor was flakey. They want to change all 4 and charge me about $700. I said no way.

Questions:

If I purchase one myself for the LF and have my tire guy install it how does the car recognize the new sensor? Is there at different part number for each wheel position?
I've found GM part nos 25758220 & 25758221. Which is the proper one for the LF tire?
Is any programing necessary?

thanks

 

Tire shop will know how to program the new sensor so the computer knows it's location. If not, run very very fast.

It uses the same sensor for all positions.

I don't know the correct part number but I'm sure someone else will chime in with that

I got told it was $125 for a new sensor for my truck.. bought one for $30 on Amazon, $15 to install and there ya go, saved $80.

 

2005 – 2009

25758220 – Tire pressure sensor
15234846 – Tire pressure sensor nut

Don't cheap out, get the new nut and O-ring with the sensor. They are generally not reusable because they deform when tightened. Tightening torque is 62 INCH POUNDS.

If you decide to order a new valve directly from Schrader, I believe they still come complete with valve, nut and O-ring, you don't have purchase the "service pack" separately.


Use a trusted tire shop or most folks here have had good experiences with Discount Tire / America's Tire. The tire does not have to be removed to change the sensor. If the shop knows what they are doing and they have good equipment they can just break the bead on the one side of the tire and change out the sensor.

 

Thank you for your help. Now that I know all the sensors are the same I will order one with nut & o-ring. So far everything I've purchased from GM parts direct has been perfect and 1/2 dealer prices. I was mostly concerned about the programing.

Best regards,
Rick

 

I bought a programmer off of Amazon for 16.00. Works great.

 

Interesting. Your link only took me to Amazon. Can you give me some details such as make & model?


BTW I am going to try to avoid my dealer as much as possible. I picked up my car yesterday, they were supposed to change the PS hoses ,but would not be in stock until 4/20.
They changed the clutch fluid, trans fluid, diff fluid, a steering wheel position sensor, battery cable and programmed two FOB's that I supplied.
$2100. In the last 37 years my 1980 has never been to the dealer, what a surprise that was. The TPSM is on it's way and I'm having my tire guy take care of it.

thanks for your reply

 

I just replaced the sensors on my 2007 a couple of weeks ago. I only have 18,000 miles on the car but the original sensors were 11 years old. Last summer I started to get erroneous tire pressure warnings from my Left Front tire even though the pressure was normal when checking with a good manual analog gauge.

I installed the OEM sensors that were in the car at manufacture, the Schrader #20076 that were used from 2005-2009. From what I read your safest bet is to go with the original equipment replacements. There are many different brands available some of which are "programmable clones" and they can be a problem.

Another thing to watch out for is that these sensors have date and year of manufacture codes cast into their plastic housings and I've read of people having bought brand new off the shelf sensors only to find out that they were manufactured 8 years ago. If the battery life in these is 10 years you are off to a bad start.

I purchased mine mail order from TPMS.com. They were about $42 US each and had a manufacture date of October 2016. I found that dealing with a specialty supplier like TPMS.com you are more likely to get a set with a more recent manufacture date. TPMS.com shipped them to me for free so that is another consideration.

I used the TPMS sensor replacement as an opportunity to clean and detail my wheel barrels and brake calipers. A local tire store installed all 4 sensors and re-balanced my tires for $100.

PS I also purchased a TPMS reset tool. I found mine on Ebay for about $20 and it worked perfectly. The procedure is simple and covered by a lot of YouTube videos.

 

What TPMS tool are you guys using? I saw some suggested in another thread but they were $100+

My 2008 had all 4 going out. I bought 4 new OEM (Shrader) sensors from Amazon at $42.00/each. A local OK Tire shop I use installed and programmed them for $110.00.

 

Thanks for the link. Do you happen to know if this works for 2005-9? Other years of C6? C7?

 

when I needed sensors for my snow tire/wheels for my Cruze I found them on Ebay for $88 and took them to Discount tire. They installed and programmed them for free. 2 winters used and no problems of any kind.

 

When mine started going out, I found what I felt was a great deal at Discount Tire--they sold sensors installed and programmed for around $75 each.

 

Based on a good friends recommendation I got these sensors, and they work excellent

 

just ordered a set for my 2012 for my extra set of wheels from Amazon. $84 shipped. should be here in a few days

 

Just check the date codes on the sensors carefully as one of the 4 I got from Amazon had a date code from 2008. Amazon came through with a current replacement, but I'm glad I took the time to look at the codes...
