If the latter, and you have a remap that upped the max boost pressure (as it should have) it is possible that the remapper failed to also change the warning limit data in the ECU.... What I mean is that the standard ECU data will have min and max points for every sensor on the vehicle - it uses these data points to decide if a sensor or some other function is "OK" or not. If, say for sake of argument that the ECU has a limit of 21psi for boost programmed in, but the remap ups the boost to 22psi, and has not altered the data point of a max of 21psi for the sensor, then I can see an error code being thrown up, even though the sensor is fine.

Just a thought, as a lot of remaps are simply not properly thought through on many fronts!
Thanks Steve. I'm wishing I'd said no to the performance remap and just had the EGR delete.
The boost sensor is new as the old one snapped when I tried to get it out of the blown intercooler. The P012b code is the same as I was eventually getting with the blown jntercooler. I say eventually as for the first few weeks there was no error code, just intermittent limp mode.
I can delete the P012b code, but it comes back almost immediately with the car ticking over, so minimal boost. I'm using Torque to log data as I drive, but can't see anything worrying in the data.

Try an ECU reset by disconnecting the battery. It's possible the new sensor has upset the ECU....

Thanks Steve. I've already tried that, but not deliberately to reset the ECU.
I accidentally left the lights on for 3 days after checking the front fogs following refitting the front bumper and then going away.
(Wife "reminding" me I needed to shower and get going)

I disconnected and recharged the battery for about 3 hours.

Just an update. A few weeks on and the truck has been fine so far. I've still got P0122b showing but no DEL and no performance issues. Fingers crossed it stays that way as I've a 9 hour round trip coming up at the end of the month.

Does anyone know if the old intercooler has any scrap value? If not it can go in the metals skip at my local tip. But I'll need to take it in my wife's car as the truck isn't allowed in without a single visit permit!

Pain in the ar$e this!,
I'm currently renovating my house and gardens, jumped on my local council website, entered my reg and got the permit.
Then after 3 or 4 tip visits one of the tip workers came over and said 'You've registered the truck as a car'.
I said 'I just went on the website and just followed the instructions'.
Pickups and Vans are allowed at our tip providing they don't exceed 3 tons.
So I've had to apply for a light goods permit, currently over 2 weeks (they have said at least 3 weeks to get one).
You have to send a picture of the first 2 pages of the V5, a photo of the truck from the front showing reg, and from the side also showing reg.

I first met this problem in Northants over 15 years ago, there are still some tips that let pickups in, my local one won't let one in under any circumstances.

I normally hire a skip.

Cambridgeshire lets you in with a pickup on its own .up to 2t trailer on a car. However that is only for individual trips not regular . However whatever you take dont go looking like a builder in anything, they will turn you away!
They are less tolerant when busy!

Thanks for the replies. I'll keep hold of the old intercooler and call in at a scrappy next time I'm passing. Which probably means it'll sit in the garage for a couple of years.

To take my truck to the tip I need to apply for a specific dates pass and tell them what I'll be dumping. Too much trouble.

I'm happy hiring a skip if I can fill it, but for odd bits and pieces that's too expensive

If I leave anything metal at the bottom of my drive it is gone the next day...
