Was this work done by ford
Customer: replied 2 years ago.
No my son is a mechanic and he did it, ford wanted to charge quite a lot of money, the recon dpf and sensor were brought from ford
Expert:  Gallagher99 replied 2 years ago.
Hi
Does your son have ford ids software and if you have the code that keeps returning
Customer: replied 2 years ago.
These are the codes P246c
P24a4, p2463, p169f, p269f,
Yes he has ford ids software
Expert:  Gallagher99 replied 2 years ago.
Hi there thanks ok
There's a few codes in there more noticeable is the code for a fuel vaporiser fault as well as blocked DPF codes and soot accumulation codes
This vapourisor is known as the 5th injector and injects fuel into the DPF to aid the regeneration process
The fuse should be inspected first as it's most likely blown
And the fuel vaporisier will most commonly be blocked
This is the most common cause of a blocked DPF in the Mondeo
Also after renewing the DPF the learned values of the DPF history MUST be reset using the PCM service function in ids as if this is not done the PCM will still think it's blocked as it's reached it's soot accumulation maximum level
This can be veiwed in datalogger
Also you can pyshically test the DPF (to see how blocked it is by using a multimeter at the DPF sensor
I can give him a few tests to carry out on the sensor so we know how blocked the DPF is

Thanks
Expert:  Gallagher99 replied 2 years ago.
I know you gave me the codes logged but all these surely can't be returning after being cleared
Regards Brian
Customer: replied 2 years ago.
Yes, they are, we have had a static regen today and these codes are still coming up,
Expert:  Gallagher99 replied 2 years ago.
Hi there thanks
Ok we need to have the sensor values checked first
The DPF sensor has 3 wires on it these checks should be done with multiplug connected
1 wire is a 5 volt reference Feed
1 is a ground and the other is a raw vintage signal out value to the PCM
Check the 5 volt reference is ok using the ground of the sensor
Next Take the reading from the signal out wire using the ground of the sensor and take the readings at the following
1- ignition on
2- idle
3- 3000rpm
4-4000 rpm
And if your don has a miti vac pressure gauge remove the DPF front hose from the DPF sensor and attach a piece if hose and applie 300 millibar ((0.3 bar ) to the sensor and monitor the voltage reading
