What is a P404 diagonise on a 2006 GMC Isuzu 5500serietruck

I would suppose that they are not common and would have to be ordered. So try a GMC dealership in your area.

Here's a link to your code.

Hi there:

Recall for the Saab 9-7X: power-window and door-lock switches

Make: SAAB Model: 9-7X

Model Year: 2006-2007

Manufacturer: General Motors LLC Mfr\'s Report Date: AUG 15, 2012

NHTSA CAMPAIGN ID Number: 12V406000 NHTSA Action Number: EA12004

Component: VISIBILITY, POWER WINDOW DEVICES AND CONTROLS

Summary:
General Motors (GM) is recalling certain model year 2006 Chevrolet Trailblazer EXT and GMC Envoy XL and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, SAAB 9-7x, and Isuzu Ascender vehicles, originally sold or currently registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. Fluid may enter the driver\'s door module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.

Consequence:
A short in the circuit board could lead to a fire, increasing the risk of personal injury.

Remedy:
The remedy plan is still being finalized. A notification schedule has not been determined yet. Buick, Chevrolet, and GMC owners will be notified by GM. Buick owners may contact the owner center at 1-800-521-7300, Chevrolet owners at 1-866-694-6546, and GMC owners at 1-866-996-9463. Isuzu owners will be notified by Isuzu Motors. Owners may contact Isuzu customer service at 1-800-255-6727. SAAB owners will be notified by SAAB Cars North America and for inquiries, owners may call SAAB customer service at 1-855-880-0808.

Notes:
GM\'s campaign number is 12180. Owners may also contact the National Highway Traffic Safety Administration\'s Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1-800-424-9153)

Do It Yourself Diagnosis and Repair

p0404-- egr flow range/performance--- this indicates that there is a problem with egr or curcuit, remove egr and clean carbon from base where it sits on intake. it may just be clogged with carbon. good-day !

There is a malfunction in the StabiliTrak system.
The only fix is to take it to the dealer. They will more than likely pull a diagnostic trouble code {DTC c0196} and reprogram the EBCM (Electronic Brake Control Module).

This is common problem with
2006-2007 Buick Rainier
2006-2009 Chevy Trailblazer
2006-2009 GMC Envoy
2006-2009 Saab 9- 7X
2006-2009 Isuzu Ascender

Diagnosing and reprogramming is a simple procedure, and most dealers won't charge you to do this service.

Best of luck!

replaced the EGR valve

Code EGR P404 is a problem with EGR (exhaust gas recirculaion), you have to replace the valve, check here for parts: partsamerica
The part costs $80/$100,. Having it done by a qualified mechanic, which is always the best choice costs around $250/$300.
