Injector Fault Codes, V8 4.4L P0205/P0305 |
|
Getting the above codes.
From what my cheap OBDII says its in cylinder #5. I hope that means Cylinder 5 vice injector #5.
P0205 is talking about a Injector Circuit Open Cylinder 5
P0305 is a misfire in cylinder #5
I ordered a reman Injector to replace however not sure that will fix my issue.
94K miles on the vehicle, just finished checking autobox fluid level. Got down off jacks and cleaned the Throttle body. Then stopped for the day. Next morning I am getting these codes when starting.
I used a BT OBDII reader minutes before I started, and the code showed up on a free app called "Car Scanner".
Then I stared the vehicle and it ran rough.
What should I try next. Sorry forum wouldn't let me post in Fault Code Area. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

You could measure the resistances of injectors.
If you have an odd one it’s faulty.
Could be connections

OK so here's my plan:
I have ordered a rebuilt injector, a ignition coil, and a full set of injector o-rings.
I will first change the plug in Cyl #5, test run. If codes remain I will switch out the coil with another coil from the other bank and see if the problem moves.
IF so I know it could/should be the coil, which I will have next week.
While doing the work I will test resistance on each injector I can get too, noting all information. Will also look into the elec charge on the connections for the injectors and coils, just in case.
Will be looking for all those tests on forums tonight.
If anyone reading knows links to these would you mind replying with the link?
Injector resistance testing
Coil Testing
Coil supply and injector supply charge testing, and anything else you can think of while I have the coils out for the plug changes.
Today as tied up with a yard sale my wife was doing, and I am worn out, LMAO. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

To me if the injector is faulty it could explain the misfire codes.

Thanks Pete, now do I just compare with others or is there a specification of such resistance.
I have some not all of the workshop manual, never could figure out how to download it from Topix in one shot, would it be there? 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

No it won’t be there.
Just compare with others.
If it’s failed it will be obviously different.
Maybe making the display read 1 (infinity)

OK so I was able to pull the connections and test all injectors on 1-3-5-7 Injectors.
1-3-7 were .000
#5 showed 0.007
So does this mean the injector on Cylinder #5 is an issue I guess?
Also sprayed brake kleen around all injetors, joint connections that were opened when cleaning the Throttle Body and no change in RPM's, so it seems buttoned up pretty good I guess.
Not sure which Ohms level I set it on, first one I came too, so possibly a lower value level would look more dubious.
I'll pull plug #5 tomorrow and see what it looks like. Might switch around a coil from the other side of the engine to see if the CEL moves to that cylinder, although looks like I might have found it, or at least part of the problem. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

I figured something was wack cause I should get
Some kind of resistance from a good injector. Thanks for the info. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Injector Resistance Help removing #5 injector |
|
OK so rn the resistance test again and got more logical numbers. 3 of 4 on that side @ .015 and #5 showed 1.0, so number 5 is the issue. Stuck open I imagine,
So how do I remove that one injector?
Anyone know of a how to? Just need to know the order of removal and items I need to remove.
I assume fuel rail (total unit) needs removed to get at #5, then Remove and Reinstall then put back the fuel rail.
Is that essentially it.
It is a V8 4.4 L as mentioned in earlier post. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

sorry I'm not sure.
looked at one here
https://www.ebay.co.uk/itm/RANGE-ROVER-VOG...SwJihcfmsu
I would:
Disconnect the wiring
unbolt the rail from the mounts. (4 bolts?)
It then maybe easier to remove all the inkectors from the inlet manifold. and once loose, replace the one injector on the rail

Ok might have gotten ahead of myself but all clues pointed to a stuck open fuel injector. Checked oil and it had definitely grown. I had just changed the oil very recently and knew the oil level was right on point.
Can’t really smell that good so no order was detected by my nose which is no good.
Pulled the fuel rails on both sides with injectors in tact. Cut key on off and on to pump up the pressure in the rails and confirm the leaking injector. Well no fuel coming out of the injector or any of them.
So I imagine that I will slide these back in and go about testing the coils by switching them around. Of coarse this means injectors and rails need to go back in.
Is there Andy thing I should check before sliding these back in. I will probably pull and clean the injectors one by one a best possible until the new o rings get here. Any suggest9ns on removing the cross over hose so I can separate the fuel rails or should I leave it alone and just pull the injector clips and injectors?
Really wanted this to be simple. Oh well down the rabbit hole I go 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

I was assuming it was a stuck closed injector
That’s was the code means.

Thanks. Ok sounds good then. |

Ok thanks for the clarification.
I'll pull and test them when I clean them. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Well switched out the bad injector after running all thru my shade tree testing and cleaning. Replaced all with new o-rings. Then started it up and had a bad leak on #3. So I pulled the bank 2 rail and pulled the injector. Thought it was going to be a bent rail but to my surprise one of the o rings were defective and just needed switched out. Ho said nine sets were too many.
Enjoyed 15-20 minutes road test before yeap the CEL Was back on. When does the CEL bulb burn out.
This time it is a fuel system circuit A high pressure fault and some coolant sensor issue.
I have currently checked all of the plugs removed from the injector work and plugs for coils removed when changing spark plugs. Also sprayed elec contact cleaner on all connections I could get to in engine bay. Nothing Shaking. Running well however shifting seems a little off and the studer is back in the auto box. From these faults I reckon. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic
