P00BD & Limp Mode - Mk7 2013

[metalworker0]

Can only answer the pattern or genuine question .. if you buy a Pierburg one .. its one of the ones that ford puts on it . and that's a safe purchase.

I would like to jump on the end of this if I may...

DId replacing the EGR fix the OPs problem?

What do people here think of the many aftermarket EGR valves that claim to be equivalent to the Ford offering for a much lower price? E.g. https://www.autodoc.co.uk/vemo/12250305

The reason I'm asking:
I have a 2013 regd. Transit 140 Sport from new. Initially brilliant but it all went downhill after the "piston burn recall" was done, although that could just be coincidence. Engine management light would come on, sometimes going into limp mode, sometimes not. It went back to Furrows under warranty, they said it was the MAFF sensor and replaced it, then fine for a couple of months until the engine management light came on again. This cycle was repeated until the warranty ran out. After that I drove around with the light on until it became an MOT fail. Friendly MOT tester cleared the fault and it stayed off long enough to get thru.

It's been off the road for a couple of years 'cos I'm pissed off with it. Now decide to try to sort it out, if only to sell it. Bought OBDLinkEX reader and downloaded FORSCAN. Cleared the fault and got thru the MOT but now I get P00BD, exactly as reported above, and it goes into limp mode every time I go over 40mph so I can no longer ignore it. With the EGR unplugged it doesn't go into limp mode and it runs fine (apart from the light on the dash). I've had the EGR valve off and cleaned it; wasn't particularly dirty - it's only done 23k miles.

I have absolutely no faith that the Ford dealer can fix it so it's down to me. What is the advice of the experts here? Replace bits of the emission control system until it works? Start with EGR or MAFF? Pattern or genuine?

ORiley youtube info' re' DPF.

Do smoke test - do soapy water test with engine running - rev it up .

Thank you for you responses.

Google AI result just trots out the text for the error code.

But some of the other results, including some on this forum, suggest it might be related to the inlet air temperature sensor on the intercooler. So I asked FORSCAN to look at these sensors with the following results:
IAT 19 C
IAT2 122 C
AAT 11 C
ACT 122 C
EGRP 0 %
MAF 17 g/s
Cold engine, at idle in neutral on yard. Outside temperature about 11 C.
MAF goes up and down with throttle pedal position. EGR position stays at 0% (presumably = closed).

The IAT2 reading correlates with other reports of a faulty inlet air temperature sensor on the intercooler. So I guess I should have that off and check it. I'll let you know what I find.

That should have been IATS2 above.

Unplugged the sensor at the intercooler, FORSCAN read IATS2 and ACT = 20 C, which I guess is some sort of default value.

Removed the sensor and measured the resistance at room temperature = 520 ohm. Dropping into near boiling water made no difference, so I guess it's not working.

New one should be here Friday. Fingers crossed.

This is the forum post I picked up on, although it is talking about Transit Custom (Mk8?). Mines one of the last Mk7s.

I don't think the temperature sensor works the way you think it does

put this into google:-

Is the IATS2 water proof, had it been submerged?

[StanT]

The IATS2 temperature sensor is the green one on right hand side of the intercooler:

which looks like this:

It's a simple thermistor - a (normally) robust, reliable and waterproof component. The housing seals into the intercooler with an o-ring.

This is the one I've replaced it with, black but in a green box

Slightly different but fits fine.

Resistance of the 'failed' Ford original is 500 ohm and gives IATS" reading of 127 C in a cold engine.
Resistance of Lucas replacement, again cold, is 12.2 k ohm and gives an IATS2 reading of `3 C, same as ambient air.
Running the engine at 2000 rpm for a couple of minutes raisde the temperature ro 22 C, letting it idle a further minute and the temperature dropped to 20C. So it seems to be doing what it's supposed to - register the intercooler and air charge temperature.

I cleared all the fault codes and adaptations and the van runs fine, very well in fact. No fault codes, good accelerator response etc. Only concern is the fuel consumption displayed on the dash of 31 mpg over a 20 miles drive at around 60 mph on a dual carriage way. Maybe it will improve as the engine management makes its adjustments over time.

For now, I would just note the intercooler temperature sensor as yet another candidate for the P00BD : Mass or Volume Air Flow 'A' Circuit Range/Performance - Air Flow Too High.

My 2012 155ps has just developed this fault & warning message, it's accompanied by a somewhat worrying noise which is coming from the driver's side of the engine when it should be making boost, noise is reduced once it goes into reduced power mode. No visible damage to intercooler or pipes, turning off & restarting returns power & noise for a short time, screenshot from Forscan. My gut says turbo failing & warning because boost doesn't match expected parameters but I'm open to suggestions before I get to pulling stuff apart.

Better to start a new post.
FWD or RWD?
Likely a split in the inlet hose after the turbo.
