P003A code

did a search didn't find anything to work with..

links, thoughts? I know its turbo related...is it something I can do?

[DmaxMaverick]

According to my research, the vanes and/or unison ring aren't able to move their full range. It or they could be fouled/dirty/broken, or it could be a solenoid issue. I'd start with cleaning the solenoid contacts, and checking the harness for any damage (easiest to access, I'd imagine). What remains in internal to the turbo.

WOW a new sensor is between $35 to over $500..hope cleaning it works

[DmaxMaverick]

Good luck!

I ordered a new one, I have 425k on the truck...

[DmaxMaverick]

What did you order? $35? $500? Something else?

I understand the 425K miles. Not really much to complain about.

I ordered the cheap one..10 days to get to me so this morning Ill take the oem sensor out and clean it to get
a few more miles out of it....*update*..I pulled the original and all looked ok, the "plunger" was free floating...
I hit it with some cleaner anyway...I dont think thats the problem, but the new one is 9 days away..

found this link and it didn't make me feel any better...possible turbo replacement...the one in the truck now
is a rebuilt....

any thoughts on another rebuilt turbo?? sources? I have 425,000 miles on the truck..

the new sensor has a more harder to depress spring than the OEM..

[DmaxMaverick]

Is that a good thing? Was the OEM sensor just tired? Did it fix anything? Do extraterrestrials really like peanut butter candy? Inquiring minds want to know.
