Strange values on some sensors

Post by Robdav99 » Fri Apr 12, 2019 5:45 am

Hi everyone,

I've been using forscan (great software btw) to diagnose some faults with ny car, p2263 mostly, sometimes p003a-16 and sometimes p0234.

I think I've narrowed it down ti sticky turbo vanes so will look into fixing that soon.

While Ive been looking into the above I've noticed some very unexpected readings on sensors.

Dpf pressure is 114kPa
Egr error is nearly 100%
Turbo vane pos goes slightly beyond 100%
Exhaust gas temp is exactly 100c and never changes

What are your thoughts?
Im wondering if the car has had a dodgy remap for dpf and egr delete or something? How can i check that?

Any ideas would be great.
Thanks Rob

2009 s max, 2.0 tdci.

We get engine malfunction message and esp light from time to time but I think I've figured that out, think its sticky turbo vanes.
Its the strange dpf, egr and exhaust temps values I've got on forscan I'm wondering about.

I would fix the issue for the fault codes your getting first and then recheck. It may even be the adapter your using as most are cheap and are not fully supported. The fault you have has a few things to check and a mechanical fault is a possibility. Have you read through viewtopic.php?f=6&t=3111#p12952

Thanks for the reply.
I think I'm using a decent lead, I was recommended this one.

The engine malfunction faults are getting less common since I put some Wynns Diesel turbo cleaner in the fuel and it seems to be helping even after just half a tank.

I have commented on that thread a couple of days ago for clarification on if I can adjust the threaded bit on the actuator to account for the error and hopefully they'll see it an respond soon.

Cheap connector but values may be accurate or may not, I’d be wary of magic potions, you don’t get Technicians in dealerships pouring them in to solve issues nor are they recommend my manufacturers. What fault code keeps returning?
