Egr position sensor code.
 

I took my car to get codes checked and i think it said it was the position sensor 1 2 3. He didnt give me a number and i couldnt see the code scanner that well but thats what i think it said. How do i fix this buy a new egr valve or can it be cleaned in a way to make it not have those codes. The car does seem to have a power loss im not sure if this egr valve would make a difference.

you can pull it off and clean it with some brake cleaner and see if that helps.

I dont think the position sensor can be cleaned.

there is no egr pos sen just an egr valve you have a cam and crank pos sen but thats it

type in google, plenty of results come up.

....and a throttle position sensor (oh yeah, forgot that one)! ;)

but still no egr pos sen :)

I know. Me thinks he cornfused the terms.

The 3400 V6 uses a digital EGR valve which does not have a position sensor. the EGR valve consists of 3 separate solenoids, each operating a different size orifice. So there's a small, medium, and large orifice and each can be opened independently or in any combination. 1 only, 2 only, 3 only, 1 & 2, 1 & 3, 2 & 3, or 1, 2 & 3.
I've been fighting an EGR code since i rebuilt the engine in my 94 a couple of years ago. I think it's P0178 indicating a problem with solenoid 3. Except that I've checked the wiring, installed 3 different EGR valves, 2 different MAP sensors, and even swapped PCMs. The code persists.
The PCM runs a fairly sophisticated test to determine if the EGR system is working properly.
Once the engine is warmed up and the car is traveling above a certain speed, the PCM looks for a closed throttle decel with no brakes applied that lasts a certain period of time. The PCM then starts operating the solenoids individually and then in combinations while looking for a corresponding drop in manifold vacuum. If the drop doesn't match what it should be (as stored in PCM memory) the code sets.
Maybe your fix for the problem will be easy but mine hasn't been.

EGR delete... Problem solved. No cons except an engine light. Cleans up the engine bay too :)
