More then likely you are having trouble with your gas tank venting system. That should have left a code, but not always the case, check it out!

2006 gmc envoy loses power and stalls out


Take your Envoy to a competent mechanic and have it checked for OBD codes, etc. Otherwise, you are just replacing parts at random without identifying and solving the real problem(s).

Take it in and find out why its back on, or take it to Oriellys and have them read your code for free

My service engine soon light came on the instrument panel on my 2004 GMC ENVOY


You need to go to a auto parts store like Autozone, they will read the fault codes for free and provide you with a printout of the reason for the check engine light being on.

Has anyone had an engine problem with their 2006 Envoy Denali...took it to two auto repair places and they both said the engine needs to be replaced


What did they say is wrong with it? The I6 engine is a very good engine, don't hear that often, especially with an 06. Lots of people have over 200K miles on it and still running strong. Mine has 178K and still going strong. Now if yours has the V8 engine, I haven't heard any good, OR bad for that matter.

My 2003 GMC Envoy XL's check engine light is on and idles rough. I suspect an O2 sensor and was wondering if a person can buy an analyzer to heck it themselves instead of paying a mechanic? Richard


You can take your vehicle to a place like Auto Zone, they can read the fault code with scanner, or you can buy a OBD II scanner for anywhere between $50 to $100. Interpreting the codes may require some knowledge of the car though.

The check engine icon is turned on. How do I retrieve 2006 gmc envoy fault codes without the expense of an analyzer tool?


A number of Auto parts stores offer "FREE" diagnostic scans in the hopes that you will buy their parts although most have a "no obligation" policy. Autozone .... Advance auto parts are a couple that offer free OBD II scans

I have a service engine soon light and the code that appeared when check is 1481, do you know what this means?


Service Engine Soon (SES) or Check Engine Light On, DTC P0480, P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness) #05-06-02-012B - (10/19/2006)

Models:2004-2006 Buick Rainier
2002-2006 Chevrolet TrailBlazer, TrailBlazer EXT
2002-2006 GMC Envoy, Envoy XL, 

Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set.

This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This contact may damage the insulation of the wires enclosed in that harness.

Replace the wire harness: 
Part Number 89024920 Description Harness Assembly, Engine Cooling Fan Wiring

Good luck and keep me posed.

Coolant Temp Sensor


The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.

P0410 Service Engine Soon light


There are many, many resons for the check engine light to come on the dash. Just because a parts store reads the code for a certain system, does not mean to just go ahead and replace the part the code says. Many different things can affect any particular system. Replaceing and EGR- lets say, because of an EGR system code may not fix the problem. Anything from broken wires, computer programming update, to clogged passages, to a bad catalytic converter can cuase an EGR code. Tech JK
