Top 20 2006 GMC Yukon Questions & Answers

If it has a misfire there should be a code. Even if the engine light is not on it may have a stored code that may point you in the right direction.

Check voltage at the 20amp locks fuse. If good, check voltage coming out of door unlock relay. One of the locks is likely pullig down the voltage due to partial short in solenoid coil.

check ICS for correct operation engine idle speed is 850 -950 rpms for auto and 750-850 for manual at 1200 rpms you are not on the idle circuits but on power circuits run the fault codes

A lot depends on how long the engine ran without oil. If the starter will still crank it, you might be lucky. If the engine has a lot of miles on it, it might be best to overhaul it, since rings and crankshaft bearings suffer the most .

55 go 62 psi at the rail

Hi Kenn,here's a video showing you how to reset your tire pressure monitoring system

I believe rear a/c unit is under passenger side wheel well cover in cargo area. You can clear the drain by shooting compressed air through it.

You did not say which engine you have in your truck,, But GM cars and trucks usually places the oil pressure switch on the drivers side of the engine near the front.. This car uses a very expensive switch.. make sure this is your problem before replacing .. you find switch.. (go to oriellys web site and look it up to see a picture of what you are looking for). TAKE The wires off of it, take a wrench or socket of the correct size and remove it. Be very careful.. Do not over tighten, you do not want to damage the threads in the block. Damage to these threads can really complcate your life.

same thing happened to me. also interior light stayed on and power locks wouldnt work. It was our door latch assembly in drivers side door. part is $110 - $250 depending on where u get it

You wanna shut it off Check tire pressure, Check owners manual

CHECK ENGINE LIGHT ON. CODE READS PURGE SOLENOID. MAKE SURE FUEL CAP IS TIGHT. UNDER HOOD ON TOP OF ENGINE YOU WILL SEE A GREEN PLASTIC HOSE WITH A SCREW ON CAP AND VALVE. THIS IS WHERE SMOKE IS PUMPED INTO FUEL TANK AND LINES TO FIND WHERE FUEL VAPORS CAN LEAK INTO ATMOSPHERE. THIS IS FOR EMISSIONS ONLY.IF IGNORED WILL HAVE NO EFFECT ON ENGINE PERFORMANCE, BUT IF YOU HAVE TO PASS EMISSION TEST LEAK HASE TO BE FOUND FOR CHECK ENGINE LIGHT TO GO OUT.

Get the gforce chip out of there & see what happensYou put the problem in there with the mentioned items

If you car is 4 years or older you might want to replace all 4 sensors. They only last for 4-6 years. If you need to replace them I found a good source fort TPMS. Just pick your year make and model. Keep is simple. That is what I like. http://www.tpmsdirect.com/ Let me know how it all turns out.

Well it depends.If the circuit board was wet it could conduct electricity and cause all kinds of problems. You could split the case and just dry it out with compressed air. The bigger question is did the moisture short out any of the capacitors or transistors. You wouldn't know that until after you dried it out. If the computer has to be replaced, you may have to get it reprogrammed by a dealer or someone with the necessary equipment.

some cars need to be clare by a good mechanic because need read information on book service

It could be the motor is bad, the wiring is bad, or that the control is shot

First you have to retreive the trouble code from your computer.The reason the light comes on is because the computer has stored a fault code in it.You will need a code reader to do this or you can get your local autoparts store to retreive them for you.

Hello: Open the hood, on the drivers side remove the cover of the fuse box, on the inside of the cover is the layout of the fuse location. Check the lighter fuse. If fuse is open it could have been caused by plugging a phone charger into the lighter socket. There are other receptacles in the truck that are made for accessories like chargers navigators etc.

TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched to the tire/wheel positions in the following order: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

The TPMS sensor matching process is outlined below:

1. Set the parking brake.
2. Turn the ignition switch to "RUN" with the engine off.
3. Turn the headlamp switch from "OFF" to the parking lamps setting four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The "SERVICE TIRE MONITOR" message will be displayed on the Driver Information Center (DIC).
4. Start with the driver's side front tire.
5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with Step 1. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage or a key.
6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
11. Put the valve caps back on the valve stems. The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the "CHECK TIRE PRESSURE" message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The "SERVICE TIRE MONITOR" message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed.
