#8 of 37 Tire Pressure Sensors by 5571madrid Jan 07, 2007 (5:38 am)
Replying to: ealexand46 (Dec 10, 2006 4:38 pm) 2004 Suburban has factory installed "automatic" tire pressure sensors. I had them all removed with a tire replacement due to a defective one and its high replacement cost (~$70 each).   Idiot light is now constantly illuminated and odometer display reads "check tire pressure". Dealer claims there is no way to remove the annoying reminders. Has anyone had success in eliminating these and suppressing the dashboard reminders?

#9 of 37 Spark Plugs, Tire Sensor Indicator by johnny4016 Jan 10, 2007 (7:15 pm)
Replying to: toe1 (Jul 30, 2007 9:33 pm) I just replaced my spark plugs & spark plug wires on my 04 Tahoe Z71. The owner’s manual and dealer tell you that the stock plugs are good for 100,000 miles. BS, on all 8 of my plugs the tips where a dark brown in color. I had 51,300 miles on stock plugs. They use AC Delco spark plugs, which were obviously bad. I replaced them with the E3 spark plugs. I bought the new E3 spark plugs at Kragons for $5.99 each; this is less than half the price most places are charging for the Denso Iridium plugs. The E3 plugs are a 3-prong plug in which all the prongs are attached together at the top. They look very cool and are suppose to give a lot better and hotter ignition burn of the fuel. By the way, my Tahoe was running great prior to me changing out the plugs and wires. You can not tell by the way it runs or the mpg it gets if the spark plugs need to be changed. On my last tank of gas I got 18.2 mpg with the bad plugs & plug wires. I suggest that the plugs be inspected at a very least at 50,000 miles if not sooner. 100,000 miles is way too many miles. They were all easy to get to except the one in the back on the passenger side. There wasn't much room to get a socket in there. Also there is a heat shield around each spark plug. The spark plug wires go through the end of the heat shields and attach to the spark plug. There is a spring on the inside of each heat shield. You can not see the spring until you pull the spark plug wire off the spark plug. This is very hard to do because of the tension between the spring and spark plug. You will need at a very minimum a pair of Channel lock pliers or pliers to pull the spark plug wires off of the spark plugs. It is amazingly hard to get the spark plug wires off of the spark plug. I also replaced my spark plug wires with MSD 8.5MM Super Conductor Spark Plug Wires. They are a lot better than the stock plug wires and only cost $64.95 for the set performanceproduct.com. I recommend these plug wires or if you could afford to put out $283.00 plus S&H & Taxes then buy the Nology Hotwire spark plug wire set. Don't wait until 100,000 miles to change out your plugs and 150,000 to change your plug wires. You will be happy you did it. In addition, you will not need to put the heat shields with the springs inside them back on when you use either of these spark plug wires. I’ve read from a previous post that someone said the springs where caring some of the spark from the coil through them, and grounding out on the heads causing a little loss of power and mpg. He said you could see this at nighttime. I didn’t check it out prior to changing my spark plug wires but it does make since that they would by the way they are installed. So this is good information about taking these springs off. They are not visual do to they are inside the heatshield. I recommend that if you buy a better spark plug wire set then just don’t put the heat shields with then springs in them back on. I guess you could try and remove the springs from the shield also. But by the time you get the shields off using a pair of pliers you won’t want to put them back on, believe me. To the person who has his tires air sensor light that comes on and stays on, this means that one of your tires has below the recommended tire pressure. I have 45psi in mine. I run 305 70R16. I just changed my tire pressure to 45psi. At 45psi compared to 35psi I get approximately 2 more mpg and my Tahoe rides a lot smoother. If your tire pressure drops below I believe it’s 28-psi the indicator light and your DIC will let you know. My sensors work great and have let me know in the past when one of my tires had a slow leak and the tire pressure dropped. I have an air pump I plug into the lighter, which works great for pumping up the tires. I bought it at Wal-Mart for around $10.00. It’s small and also has a light on it so you can see at night if you need to. I keep it in the back of my Tahoe and recommend this to everyone.
#11 of 37 Tire Sensors on Tahoe by qrutherford Feb 19, 2007 (7:42 pm)
Replying to: toe1 (Jul 30, 2007 9:33 pm) I recently took my factory wheels off of my 07 Tahoe and replaced them with some 20" wheels. Now, I am receiving a "CHECK TIRE PRESSURE" message. I have tried to relearn the tire positions, but that did not work.. Does anyone know what to to do about the tire sensors? Are they attached to the factory wheels???

Replying to: qrutherford (Feb 19, 2007 8:42 pm) Yes, the sensors are inside the factory wheels.   Who replaced your wheels? Did they not know that the sensors are installed inside the original wheels and that they should take those and install inside the new wheels?   Arrie

Replying to: toe1 (Jul 30, 2007 9:33 pm) The tire sensors are located on the valve stems on the inside of your tires.   So if you replaced your rims you should have unscrewed the tire sensors and screwed them onto the vlave stems of your new rims. They are very obvious on my 2004 Tahoe and can not be missed. They can be broken by the mechanic if he/she is not careful when removing your tire from the rim.   Wal-Mart broke one of mine and had to purchase a new one from the dealer. It is a dealer item only. They cost about $64.00 each for the 2004 Tahoe. The 2007 might cost even more since the system on the 2007 is a little more advanced.

Replying to: toe1 (Jul 30, 2007 9:33 pm) No, he thought they were like the 06 sensors, but he said they were different and didn't find them.. then we were told that we would have to buy some.
#16 of 37 Got a 2004 Suburban? What tires came on it? by jeffnc May 09, 2007 (9:21 am)
Replying to: toe1 (Jul 30, 2007 9:33 pm) Trying to find out what were the original tires for a 2004 Suburban. Please reply with size and exact make of tire originally equipped (i.e. 17" Bridgestone Dueler A/T). Also please state 4x4 or 2x4. Thank you very much for your time.

Replying to: ealexand46 (Dec 10, 2006 4:38 pm) Here is a link to a site that will tell you how much your speed will be affected by a different tire size other then your stock tire.   http://www.1010tires.com/TireSizeCalculator.asp?submit=yes&vehicle=yes   Touchlinc
