Arrrggghhh - 2

ok. so today I got my no1 fuel injector in.

car starts, runs and seems much better than it was at idle and revving. Took for a very VERY short spin round the back, and the MIL light came straight on, but rather than come on and off like before, it stayed on.

Now I am not sure if the length of drive I did was enough to show up any other faults, i assume not-engine wasnt fully warmed up, it has thrown a code. Now I have number 18 - Fuel Quantity adjuster etc.

sigh. so, who knows what this one is?? if it helps, this code came up a long time ago, but did clear, so wasnt present BEFORE I did the injector, and the car had been driven a good 30 mile, so not sure why this has turned up, unless its to do with the new injector?

 

[Timbo_1975]

Unlikely really. The FQA is integral with the pump.

I would clear the codes, then restart the ecu, so it can relearn and go from there.

 

[clivvy]

When you say restart ecu, do you mean just clear the codes, or is there a way to reset the ecu??

 

[Timbo_1975]

yes- disconnect battery for an hour.

 

[clivvy]

Ok, this was done before I fitted the injector, but will do it again...

Best of luck with it, hope it's all sorted soon.... ...... I've got you down on my list to try a few Peak District lanes!! :thumbs

Have got my bus running again (still a few bits to sort, but running )

helps.

ok, I reset the ecu again this evening, then went out on a drive, covered about 7/8 mile maybe a bit more. MIL light came on after a while, engine was already warm. MIL went off, came on a couple of times, but mostly stayed on. I got just a slight judder when it did, no real loss of power but i wasnt really kicking it. Got 50 just fine, mostly traveled at 40. When driving, car feels MUCh spritelier, and theres a much more pronounced whine presumably from the turbo/K&N.

Anyhoo, because of the MIl i got a bit nervy, so headed home. parked up, and literally as we settled to get out, it stalled. now its the part i dont like, the stalling. Anyway, I re read the codes, I still have code 18, and 47 has coem back, which I expected. I will order a CKP sensor tomorrow from Andrew Pages, cos I have no idea where else to get one from. The thing that is bothering me is code 18 - Fuel Quantity adjuster/position sensor-malfunction. Says it could be - wiring, supply voltage, fuel quantity adjuster/position sensor, ECM, or fuel injection pump.

I had a visual check of the pump, no leaks, dry as a bone. I tried to trace the plug from the pump, unsure which one it is though, can anyone giev me some advise on checking this code 18??

Also, when it stalled, could that have been cos of the CKP sensor error?

I'm sorry i cant help you more with typical causes of your fault codes - ive not had any on my truck yet (touch wood!!)

The CPS could well be the problem as far as the stalling is concerned, they often fail when hot, especially about 10mins after shutting down a hot engine- typical failure mode is she wont restart til cooled off. A tell tale sign is the tacho needle stays on 0 whilst cranking.

With regards to the FQA, can you check the pump wiring visually at the multiplugs ? You'll need to carefully r&r the rubber boots behind the plugs to check for secure wiring as well as parting the plugs to check the pins.

Thanks for this, i'll speak to Andrew Pages tomorrow about a new ckp. Last time they said its direct from bosch, so I think i will make them promise i can return if incorrect.

As for the FQA, can you direct me to where the pump wiring is, is it the set nearest the intercooler? I am not sure about the rubber boots either...!

 

[Timbo_1975]

If you have the Bosch system you will have a large circular connector just to the left of the intercooler, along with 2 smaller sqaure ones- one for the CPS (two pin), and the other the glow plug supply (very thick red wire).

If you have the Zexel system, then its a rectangular plug.

There is a rubber boot that covers the rear of each half of the connectors and is secured with a cable tie.

 

[clivvy]

ah right, I have zexel. so I know where the plugs are, but not sure which plug, but obviously can trace that now, will have a look see later this week!

cheers timbo!:thumbs

 

[clivvy]

you know the ckp sensor, is it the same on any other vehicle?

 

[clivvy]

helps!

dammit. I spoke to Andrew Pages just now, they do sell a ckp sensor, £70 odd quid, for 97 onwards terrano 2. I asked him to describe the plug, he said rectangular...well, mines not, is sort of rounded. same three pin, just different casing...now what do i do?
do i now give in, and go to Nissan Dealer?

 

[clivvy]

...additional. i called a nissan dealer, they think they found it, £188. sorry, but thats £100 dearer than the most expensive one i have seen so far, only it has the correct plug on the end, cant i just modify the plug?

 

[clivvy]

CKP sensor anyone? Seems I have an odd one. when i ring places for quotes, they can find a sensor for a 97 terrano2 no problem, but describe the plug as square ish, where as mine has rounded sides, any one else have this problem, can i just swap the plug end??

 

[makeitfit]

Any chance you can get a pic of it to be safe. I think I've still got a spare s/h one but what shape it is and where it's living now:augie

 

[Liam]

Have you considered that the one fitted on your motor might be the wrong one? It is possible that yours is incorrect but I suppose the only way to be sure would be to call a Nissan garage and give them the numbers on yours for verification. I do recall from my time in the motor trade a long time ago that car manufacturers usually had alternative suppliers of some parts and these might do the exact same job but looked different. Worth a check with Nissan to see if this might be the case. I would be inclined to try another part regardless of shape if the connections are the same. You must remember that companies often make cosmetic changes to parts for ease of manufacture and also so that their part might be used in other vehicles.

 

[Timbo_1975]

Just to amend my post, the CKP is infact a 3 wire item- only the earliest were 2 wires.

The 3rd is a screen of the cable to reduce interference, which terminates at the ecu's earth point.

 

[clivvy]

Makeitfit-I'll get a pic up tonight.
Liam-yes, I do wonder if it's wrong but the plug fits the socket do...
Timbo- mine is three pin, and the car shops sell a three pin one, but with a square socket, so it's unclear if this will fit my plug?

I'll get sone pics up tonight, this is turning into a mystery!

 

[clivvy]

ok, heres the pics:

and this is the one i can get cheaply:
