On a 2002 Envoy you turn the key to run but don't start it. Then push and release the gas pedal 3 times within 5 seconds. The change engine oil light should blink for 5 seconds meaning you have reset the system. If it doesn't blink for you do the procedure again. I'm pretty sure its the same on a 2003. Good luck.

What can cause a high cooling fan speed error in a 2002 Trailblazer?
These errors are caused by software problems in the PCM. General Motors warrants this defect for unlimited mileage. Take your vehicle to a dealer for a free PCM upgrade to correct this and NUMEROUS other concerns (stalling, high idle, high fan speed, shift problems)
This is garbage- GM will tell you get real- totally rubbish. The problem lies in their monopolized parts (Dealer stock item only) Common problem - expensive part (entire fan assembly) and labor- (entire front end disassembly) I paid appx. $600.00 for this error code to be cleared. Good luck!
EVERYONE SHOULD BE AWARE THAT IF YOUR PCM FAILS IT IS COVERED UNDER THE (LONG TERM) EMISSIONS WARRANTY. YOU DO NOT HAVE TO PAY TO HAVE IT REPLACED. IF THE DEALER WANTS YOU TO PAY FOR A NEW PCM THEN CALL THE 1 800 NUMBER FOR CHEVY (ON THE WEBSITE)
This two answers helped me a great deal. I had the exact same problem on my 2003 Trailblazer. The check engine light came on, I took my vehicle to autozone and they told me the code was P0495 (cooling fan speed high)but they did't know how to fix the problem. After loking at this two previous answers, I called the dealer and they told me that it would cost me $89.00 to reprogram my PCM. I took my vehicle to the dealer and before checking my vehicle, the mechanic noticed the noise my vehicle was making (like a jet engine) and told me that in addition to reprograming the PCM I needed to replaced the fan clutch. The total cost was going to be $747.00. I didn't have the money so I went home and looked on eBay. I purchase a brand new fan clutch for $130.00. I am not a mechanic and it took me about two hours to replaced the fan clutch. You need a 12" crescent tool to remove the fan clutch from the water pump pulley. After replacing the fan clutch, I was on my way to the dealer to reprogram the PCM but noticed that the vehicle was working great so I skip the dealer and went to the 7 eleven and got me a six pack to celebrate. My vehicle is working like new. I hope this could help somebody out there. Good luck
I have the EXACT same problem. My local Chevy dealer wants to charge me $800 to repair! I looked at the fan clutches on eBay (ZBRA) for $130. I noticed they have an electical connection but I couldn't quite see one on my clutch fan. Am I just not seeing the connection or is it possible that I don't have one. If I don't have a connection, is there a place to plug-in the new one? ALL 2002+ TRAILBLAZER/ENVOY/BRAVADA/SAAB 97X ETC HAVE A FAN CLUTCH ON THE I6 ATLAS ENGINE AND THERE IS ALWAYS AN ELECTRICAL CONECTOR TO IT. LOOK FOR A DANGLING WIRE THAT MAY JUST CONNECT TO A PLUG ON THE SHROUD.
If you do not know when it was changed last I would highly recommend you go ahead and change it. With this many miles on the odometer it just makes good sense to not take a chance.
A lot of times with the computerized niceities on vehicles "OC" means open cicut. Trace the wire and look for a broken/disconnected/or loose wire (it could be a live or active wire)) Open Circut on these units means that the sensor has failed.
The above problem is correct, but the actual problem is a sensor behind the grill. It is grey or black in color, it is the ambient temperature sensor. The cost is about 60 bucks dealer only item. To get to this sensor you will have to remove the front grill there are six screws, you will also have to unplug the headlight washers if equiped. The whole process will take about ten minutes.
The Camshaft position actuator solenoid controls the exhaust camshaft retard position. From 0 to 25 degrees. It is driven by a pulsed electrical signal from the ECM... much like that of a fuel injector. It is located on the front-passenger's side of the motor... on the head. Removal requires the partial removal of the steering pump. It is prone to failure mainly due to debris in the motor oil that flows into it. An oil change and/or removal of the solenoid actuator to clean of the screens of it can sometimes resolve a related DTC.
How do you replace the front sway bar link?
Replacing sway bar links is relatively easy for the 'average' do-it-yourselfer; although it can be frustrating trying to replace them on your back.
They are usually loacated on the lower control arms as a long 4-6" bolt or PVC rod connected to the sway bar itself, which rides along the undercarriage of the car and connects to the opposite control arm in the same manner. It is, essentially, a torsion bar that refers weight to the opposite side when you are cornering to maintain steering control.
Depending on the year of your Taurus and the configuration of links that you have; as well as if it is already broken or not; first spray it down with penetrating oil and let it soak to make removal easier.
Raise the front end EVENLY and brace the control arms with jack stands (the hanging weight on the control arms can help keep the bolts from spinning when you start to loosen them. The floor jack braces will keep the control arms from falling too far once the bolts are loose.)
Once the old parts are removed, replace with new pieces from your kit in the reverse order. Rather than trying to pry down on the sway bar (to make the bolts reach), lower the car VERY GENTLY with the jack stands in place until you can tighten them properly (according to the directions in the kit).
Once they are properly tightened, raise the car enough to remove the jack stands; lower the car, and you should be good to go. Probably wouldn't be a bad idea to have the alignment checked, too.
How do you remove the resonator from a 99 vw passat 1.8t?
Unfortinatly you have to cut it of. There isn't a sleeve like the DownPipe. Get a Downpipe-back exhaust, or cat-back!
My Envoy has the inline 6 cylinder and gets about 22mpg on the highway. I'm not sure about city driving but it isn't much less. If I had to guess I would say 17. Both are acceptable to my in exchange for the comfort that comes with my Envoy. I noticed that the gas mileage goes down considerably if I "get on it" too much. If you are driving the Envoy hard, like taking off fast from stop lights or hitting passing gear quite a bit when your out on the highway that would have a significant impact on gas mileage. It does with my Envoy. I drive like an old man. I cruise at about 70 mph on the highway and the tachometer is right around 2000 rpm. Maybe a little below that. In town I drive the speed limit and accelerate at a normal speed too. I never hit the accelerator so hard that the transmission drops a gear and the engine rpms jump up by a few thousand rpms. If your driving habits are like mine then I would check the oxygen sensor.
How do youReset envoy security system?
There could be many reasons for this failure. Normally it is caused by a faulty passlock sensor. The ONLY way to be certain is going to be by using a class 2 scan tool with the ability to read more than simple check engine lights. The security light blinking is much like a check engine light and with this tool you can find the trouble code associated with the no start condition. There is a simple relearn procedure that you can try. It may work, but if it doesn't you are going to be stuck getting this to someone with the proper diagnostic equipment to find the failure. Here is how the relearn is done.
- Turn ON the ignition, with the engine OFF.
- Attempt to start the engine, then release the key to ON (vehicle will not start).
- Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
- Turn OFF the ignition, and wait 5 seconds.
- Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle is now ready to relearn the PasslockTM Sensor Data Code and/or passwords on the next ignition switch
transition from OFF to CRANK).
ImportantThe vehicle learns the PasslockTM Sensor Data Code and/or password XX the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
- Start the engine (the vehicle has now learned the PasslockTM Sensor Data Code and/or password)
Even if this does work, i would still have the vehicle looked at as it may happen again and be permanent. Feel free to contact me with any questions or if you prefer a second opinion. Good luck!
