Default 2004 Freelander with trouble codes: P0174, P1472, P1471, P1775, and P0705

I would really like to know what is going on with my Freelander anyone who has some info for me would be absolutely great!

The other day the DOWNHILL ASSIST WARNING light came on and when I turned off my car then turned it back on it was gone, but as I was driving for a little more the SERVICE ENGINE SOON light came on

I ran a code scan and these are the ones that showed up:

P0174: System to lean (Bank 2)

P0705: Trans Range Sensor Circuit Malfunction (PRNDL Input)

For the following codes it said: "DTC definition not found", but I did some research and it looks like the codes mean the following:

P1472: VIS power/butterfly valves always open?
P1471: VIS balance motor valve always closed?
P1775: Gearbox fault?

If anyone has any info that could help me that would be greatly appreciated!

Thanks

look at the lean code first. look for something broken like a pcv hose. if nothing is broken then smoke test it to see a leak. if no leaks then look at a maf sensor.

Did you get the fuel pump recall done yet?

Regarding the P1471 and 1472 codes, I believe those were the same codes on mine, requiring replacement of the entire intake manifold assembly.

Good luck,
Julian

I am having a similar problem:


We have a 2005 V6. It started running very poorly last week. The power just dropped off and now it idles very poorly and sometimes just stalls completely. It cannot be driven.

I pulled the following codes:
P0171
P1471
P0305

I replaced both VIS motors and it still runs like crap. Can you provide any suggestions?

Question Misfire and Lean. Any Suggestions?

I have a similar problem, only mines is when you floor it.
I bought the car about 2 month ago and its been in the garage and engine has been rebuild. I'm stuck on this misfire codes that keeps popping up.

P1471, P1472, P0300, P0301, P0302, P0303, P0304, P0305

Under normal driving up to 70 mph it would run smooth and no codes will pop up. It's when you floor it at any speed even from stand still, that the check engine light pops up when the rpm reaches around 6000. The car lags all the way up to the 6000 rpm point and misfire randomly until you stop and restart the car. After restart it'll run smooth again like usual.

I have done:
spark plugs, wires, and all coil
have open up both VIS, cleaned, soldered and resealed
checked hose, manifold (exhaust and intake) for leaks
checked and cleaned MAF
brand new timing belts(front and rears), accessory belt, air filter from when rebuild
refilled transmission fluid and front differential gear
checked all injectors with noid light(haven't bench flow test)
check for sparks at all plug wires (ok)

I'm pretty much stuck and it's still doing the same thing. I might be able to come up with some more tested on more of the electrical but for right now bumbed out. Anyone have any suggestions on what else to look for, it'll be a big help and greatly appreciated.

I will keep post on the status of this problem until it gets squared out.

Smile Mines Broken Too!

I'm having the same issues LGREF9, except no as many misfire codes...have you found a solution?

I haven't had the fuel pump recall yet and i'm hoping that will fix my issues. I reeeaaaally don't want to replace the Upper Intake Manifold, that will leave me broke.

Thanks!

Sorry chase nope haven't figure out what's causing it. I'm just driving it carefully so that it doesn't misfires on me and it hasn't been acting up lately except once on the highway when I floored it to switch lanes. I'm suspecting both or one of the VIS motor might be fried and going to do some test this weekend. I remember some oil getting in there when I first opened them. I'll probably forget to post back up here my results but I have subscribe to get email notification so remember to remind me so I can help out if I did find a solution.
