It's new and clean I don't know what to do¡¡¡¡¡¡¡¡¡
Hi Geraldo, Have you had the code cancelled on a scanner? If not it will still be recorded as a fault. Regards John

Your EGR valve is located behind your throttle body and injectors, and it is attached to the intake manifold. It has two bolts on opposite sides of the valve and a vacuum line running out of it. Disconnect the vacuum line, remove the two bolts, and pull off the EGR valve. The EGR's on these trucks tend to get clogged up with carbon and stick. Take some carb and choke cleaner, and a small pick or very small flat head screw driver and break up the carbon inside of the valve. Be careful not to puncture the rubber diaphragm or you EGR will be no good after you get done cleaning it. Once you get all of the carbon deposits out of the EGR, assuming you buy a new gasket for it, put the gasket between the valve and intake manifold, tighten screws, and plug the vacuum line back in. This should solve your problem!

good evening to you and welcome to fixya
before spending money go and unhook the battery cables and let set for about 2-3 minutes then rehook and start and see if problem goes away and then comes back. if problem comes back or still exist then check the wires for signal and ohm resistance that may be abnormal. check this out and lt me know if i can help you anymore.

Remove the EGR valve and look in the ports in the intake. There is a good chance they are stopped up. Good Luck.
SOURCE: engine light came on and code read po403 egr valve
This code is a cylinder number 8 glow plug failure. These can be read using an ohm meter.
A good plug will register between 0.6 - 2.0 ohms

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.
