3.0 SDV6 - P242D and restricted performance.

Hi. Has anyone replaced an exhaust gas temperature sensor on an SDV6? I have a P242D code coming up after a few miles (I’m assuming it’s trying to start a regen). Restricted performance disappears if you stop the car and restart and then reappears a few miles down the road.

No obvious symptoms and MPG hasn’t dropped.

Have you tried to force a regen by driving for about 20 mins at higher revs than normal

Is that a thing?

I've come from an L322 and I was under the impression regens could only be forced with the aid of software.

With the L322 it needed at least 1/4 tank of fuel and a steady 50mph (which was 1200rpm in top). This was the criteria for a regen and no amount of added revs made any difference.

I think the problem is that the temp sensor is not telling the PCM that the regen can begin.

Happy to give it a go if that isn't the case though.

No need to rev for a regen as Kooky says. Just a long run above 50mph with a good load of fuel in tank.

Had both replaced. The code is P242D. It’s post DPF if the code is to be believed, I just wondered if anyone had had the same issues.

P242D-00 is related to the second (post cat) exhaust temperature probe (cable or sensor fault)

Had it in to LR today for further diagnostics. Definitely the sensor. Quoted £400 to replace. Fortunately it was the one that takes 1.8 hrs not the one that takes 7.5

I have 2 Indy’s in my area. One wouldn’t do the work as it was under warranty and the other couldn’t see it for 3 weeks.
