Ford Transit Connect 1.8 HCPA 2006 - Codes P1211 & P0251, dies under load - Fixed #

Posted by Liam Hall on May 9, 2012, 6:13 pm

Year of Manufacture *: 2006 '56
Engine Size and Code *: 1800 HCPA
( Optional ) Scanner Used: SOLUS PRO
( Optional) Fault Codes: P1211, P0251

Hi,

I have this van in at present, when driving under load the van dies with glow light flashing.

Code read and the following codes were present;

P1211 'Injector control pressure sensor above/below desired'

P0251 ' Injector pump fuel metering control A malfunction'

I went straight for the vantage pro, supply voltage at IMV was battery voltage KOEO, but sig test was 14v virtually flatline KOER, no pulse at all.

I have read the archives on this one, and there seems to be many factors.

I have checked for fuel filter, this is newish, but not fitted by me.

I have not captured the fuel pressure in live data when the failure happens as I am on my own today, cant drive and operate a scanner!

My thoughts are that I have a faulty IMV, but if anyone has any insight it would be gladly appreciated - I HATE fitting parts that do not cure a fault and make me look daft.

Thanks in advance

Liam.

When I see these fault codes an injector leak off test normally finds the fault

I had considered that, but do you not think I have found a faulty IMV, given the lack of a waveform on the scope?

I will carry out leakoff test tomorrow, just to be sure, but I have my doubts.

Thanks for your input, will follow up tomorrow.

Liam.

IMV?? Sorry to sound stupid but what do you mean by IMV?

So you have no PWM to the IMV(inlet metering valve) if you think it's the IMV at fault could you not put a dummy load across the two wires and see if you have the PWM signal then?

When you say dummy load, do you mean a 21w bulb or similar?

I have also just thought of something else...
is the IMV flatline at batt voltage because there is a duff injector wasting all the pressure, and the rail pressure sensor is commanding more pressure?

I will get the leakoff test done and come back with results.

Performed leakoff test, all injectors similar, no 2 slightly higher but not excessive.

I've ordered the IMV as I feel confident thus far.

Yeah a 21w bulb or similar is what I ment have you tried commanding the pump to maximum pressure whilst your leak off kit is connected?

Are you sure there is definatly no PWM signal on neither wire to the IMV?

Carl

Hi Liam,

Have you checked the fuel low pressure/flow with a gauge ?

Cheers Glyn

I have tried to command full pressure, but solus pro doesnt have the option.

I have tried both wires and there is no pwm signal, I think that the IMV is either shorted or stuck.

If it is the IMV that is cauing the issue then your PWM should come back by putting a load on the circuit with the IMV unplugged?

You dont need a scan tool to drive the pump to maximum pressure

I think the fact that the van runs and drives means that there is a pwm signal to the imv? Perhaps it is a problem with the scope set up?
You could also check the injector leak off under load conditions.

Hi Liam,

>>> I think the fact that the van runs and drives means that there is a pwm signal to the imv?

I'm with Ray on that !!

I'm not fully conversant with Snappy scanners, but presume you can get a duty cycle reading of PWM (shown in %age value) of IMV in live data ?

Would also expect a rail pressure value shown.. What is rail pressure at idle and how does it alter when engine speed / load is increased?
Especially at point where coil light starts flashing..
Would suggest pressure deteriates rapidly around that point ...
May be wrong, but happy to be corrected

.
Cheers, Tony

Defintley agree with tony and ray and I think a pump proof test with leak off bottles connected may possibly show up your fault

I too suspect pump, based on your input and a good nights sleep to further digest the info.

I have a man with sealed rail kit checking the pump on monday - another piece of kit I want, but have you seen the cost?!

Thanks again.

Liam.

This one was pump, unfortunately.

Also have a focus here with the same codes and driveability issues.

I think that I can safely bypass signal tests etc and go straight to a sealed rail kit to prove pump integrity first from now on with these codes.

Are these particularly common does anyone know? The fact I have two may just be coincidence?!

Thanks to all that gave input.

Any recommendations on makes/suppliers of a sealed rail kit and pump dummy kit?

Liam.
