Limping Terrano

[Nunosi05]

Hi everyone,

I have a problem with my Terrano II 3.0 di, just bought it with this problem, hoping that is not a major issue.

Hope someone can help me with this.

The symptons are:

When driving, the car gives a kind of hickup and the engine light comes on.
Similar to running out of fuel. From there on, the car has lack of power, struling to the smallest elevation, even in the highway.

When I turn off the ignition, and tenho on, the engine light goes off, until next time.

I know that in the last months the car had the turbo and fuel injection pump Refurbished

If I fix the car and don't pass it on, I will surely become a full member as I plan to keep this car for a while

Best regards

If the pump has been refurbished then I would go with fuel filter but I would have thought he filter would have been dome with the pump so it is a bit early for it to be blocked to this degree, you need to look at a recent thread on here started by me called harlowmavs motor, in that thread you will see pictures of the diagnostic socket, we need to know if you have pin 7 or not as the presents or absence of this wire determines how we check the codes, Rick

Hello sounds like its going into limp mode!! Fuel pump fault could do that I think, also maybe turbo because as far as I know it's a vnt turbo that's linked with ECU somehow!

Somebody more qualified than me will be along though

Sorry the pics of the connector are not in that thread, and cannot remember which thread, so look at your connector it is under the dash to the right of the column there are 8 pins in two rows, and if you look at the plastic one row will have a wider part, look at the pins on the wider if it is at the top pin 1 is first on the left pin 8 last on the right if there is a connector next to 8 then you can use a cheap obd2 reader, if no connector on 7 then look in the downloads re code reading it will show a 14 pin plug but bridging the two extreme outer pins on the bottom row has the same effect, just follow the download to get the code once you have that, lots of the codes are given but if yours is not there I have a better list, Rick........ ps if you have pin 7 I am not sure if the paper clip method works but you can try it

My OBD reader doesn't connect to the ECU. So i'm almost certain that there is no Pin 7.

OK then turn the ignition on and momentarily short the two extreme bottom row pins then your mil light should flash the codes, cannot remember the sequence but as said it is in the downloads, quick links next to log out, Rick

Sorry to hear about what's going on with your truck, vp44 pumps can be tricky!
Fortunately you should have a warranty to fall back on:thumb2

 

[Nunosi05]

The pump was sent to repair by the previous owner, don't know if the warranty is something that I can ask for, and they are 300 miles away !!!

The two pins that need to be connected to read any stored DTC's are pin 1 (Check) and pin 8 (IGN).

Hi, first thing that I noticed was a broken wire in the MAF socket, and another one is striping.
Did a quick fix on it.
Now the seems to go a little smoother, the hickups still come up, but in a lower rev range and usually after a roundabout. Which makes my guess that is a fuel related problem.

Will check the code error later in the evening.

 

[Nunosi05]

Ok, so I got the following codes from ecu.

12 - MAF ( broken wire ) fixed

43- crankshaft sensor

73- ???? Doesn't come in the manual

Help !!

 

[terranosaurusdoug]

There is a sticky for crank sensor but its for 2.7, I don't know if it translates to 3.0 or not.

I think Rick, (solarman) said he has a better list of fault codes.

 

[Nunosi05]

Was reading the codes in the wrong way, is 102, 403,and 703.

:banghead:banghead:

OK crank sensor is on the front pulley, follow the wire up to the plug top left front, unplug it and read the ohms, should be 1500 ohms, re 73 this is bad communication ecu-IP so check connectors etc, Rick

 

[Nunosi05]

Will do that , thank you solarman216

Cleared the codes on the ECU, and went for a run.

Before the run, checked for errors and gave the " no errors found " code.

After a while engine light went on, checked for errors and the 703 appeared again.

Could the fault be on pump ECU?

yes they are renowned for it, apparently it was do do with the solder used on the joints and they break down, but if your pump was refurbed they should have addressed that, but do check the connectors first, Rick

Ray is that pic of your actual socket as the shape looks different ?

I thought there were only 2 types or is it my eyes :nenau

Both the black and white connectors are the same, they are both 16 pin J1692 specification. May be a trick of the light?
