Crd voyager has come up with a fault code p0069 manifold

Customer Question

Crd voyager has come up with a fault code p0069 manifold pressure /barometric pressure correlation I've changed the map sensor and plug the egr vaccum solenoid and maf sensor but still cannot get this fault to clear I also cannot find anything regarding a barometric pressure sensor
JA: Do you have a scan tool to read the codes?
Customer: Yes
JA: What year is your Voyager?
Customer: 2006
JA: Are you fixing your Voyager yourself? What have you tried so far?

Unfortunately being at work I'm only able to type as I am currently working on my vehicle (the chrysler) and completing work on a customer vehicle
Expert:  Gavin Perry replied 19 days ago.

Have you checked the inlet manifold swirl flaps / motor see image that is if it has swirl flaps fitted.

Customer: replied 19 days ago.
My vehicle does not appear to have them fitted

They would be underneath the manifold and what is going on with the wiring.

Customer: replied 19 days ago.
There doesn't appear to be any motor on either end of the manifold and unfortunately I had found a few broken wires but haven't gotten around to tidying them up as of yet
Expert:  Gavin Perry replied 19 days ago.

ok due to time reasons i will have to opt out and let another expert take over regards Gavin.

Dear customer, the error code, as you will understand, speaks of pressure problems in the manifold, this can be due to various factors such as inconveniences in the map sensor, vacuum leaks in the air intake system, wiring problems, problems in the throttle body, damages in the the intake manifold and so on.

There is something that catches my attention in your query and it's that you are indicating that there are some broken cables, I am concerned that these cables are related to the map sensor, as i see in the picture I see that you have several arrangements at the electrical wiring, I recommend that verify very well that the electrical wiring is referring to the map sensor, surely your fault is the wiring.

Firstly I changed the vaccum solenoid as it had a fault for the egr but as the only difference I could see between a vag one ams chrysler was the plug so I swapped the plug and fitted a new solenoid the map sensor repair I believe is fine as if I unplug that connector the fault that comes up is boost pressure sensor a high so I don't believe there is a problem with the wiring repair but the fault only cam about after replacing the egr solenoid
Expert:  sebastian manrique replied 19 days ago.

Dear customer, then you could be presenting vacuum leaks to the intake system, I thought about the wiring failure because of the picture you sent me wherr I see that the wiring is manipulated, but as now you tell me that it was after the EGR valve repair, it could be a vacuum leak inconvenience, it would be nice to get into the live data stream through the diagnostic tool and see how much the manifold absolute pressure is, this is the best way to check if the sensor is truly correct.

Customer: replied 19 days ago.
The sensor is reading 254kpa even with the engine off
Expert:  sebastian manrique replied 19 days ago.

Dear customer, is the signal stuck in 254 kPa and does not change even with the engine running?

Customer: replied 19 days ago.
It stays at that at idle don't think it changes much under load but checked for vaccum without the sensor in by hand and there is definitely vaccum there
Expert:  sebastian manrique replied 19 days ago.

Dear customer, then the problem is with the sensor. Because the pressure when turned off is the same to the atmosphere equal to 100 kPa and when it is under load shall be around 300 kPa, this vary according to the altitude.

Customer: replied 19 days ago.
I should attempt to replace the sensor even though I fitted a new one from gsf?
Expert:  sebastian manrique replied 19 days ago.

No, you should see what is happening with the sensor signal, because from what I see it could be a wiring problem, but if you want to try another sensor, it isn't a bad idea, the procedure itself would be verify sensor and verify wiring, until that there is no variation in the map sensor, the error will not be corrected.
