Some days... Error 34 - Injector needle lift sensor and other issues.

[Lazy-Ferret]

I needed to get over to Suz's dads yesterday, to do some urgent electrical work in the garage. He has dementia, and is disabled (completely wheel chair bound), so he has carers going in 4 times a day, and among their duties, they do his laundry.

He had a combined washer dryer which is out in the garage, but when it failed at the tail end of last year, he purchased two new separate units to replace it. With the old machine, the carers put the washing on in the morning, then at lunch put it to tumble dry, then at tea, put a new load in the washing machine etc, but now with two separate machines, the carers put a washing load on in the morning, then at lunch swap the washed load to the tumble dryer, and put a second load into the washing machine. The problem is, the feed to the garage is fused at 13amp, so with 2 high current devices, it keeps blowing the supply fuse, and to make matters worse, he has to have puréed food, which we we order in bulk, and the extra is stored in a freezer in the garage as well.

The problem is, with the carers changing all the time, trying to train them is not working, and despite repeated notes to them that they can't use them at the same time, they still do, often blowing the fuse. The problem is, now, instead of calling us when they do it, they pretend not to notice for a few days, hoping that when we call over, I notice and fix it.

The problem is, being 40 odd miles away, we tend to only get over there every couple of weeks, unless we have a specific reason to go over sooner and because of this, we have had the freezer defrost where the power has been off for 4 days, and the last time we lost £170 of food....

Not only that, but he has an electric buggy, which is stored in the garage, and he always gets home, and plugs it in to charge. He does not look at any of the lights, as we did not want to confuse him with any extra things, when teaching him how to use it. So he did not realise it was not being charged, and went out several times on it over the week, resulting in him running out of battery on one of his trips, and stuck in the middle of nowhere... Luckily we have fitted a tracker to it and happened to actually have popped over to see him when this happened. We had to push him home for over a mile.

Anyway, enough back ground, the time had come to sort out the Power supply out there, and make it safe, and new....

I purchased all the bits I would need to run a better feed to the garage before hand, getting a few great deals from Ebay, then loaded them plus all the tools I would need into my car, ready to set off. I went to start my car and the MIL light stayed on... tried restarting it a couple of times, but it stayed on.. Popped into the house, got my laptop, connected up ECU talk, and discovered "34 Injector needle lift sensor - incorrect signal"

Bummer....

I really need to get over there and sort him out, so since it was unlikely to be a quick fix, I transferred all the bits I had loaded into the my car, over into Jiggly and went to start the car... Only to discover a Flat battery....

POUT...

I jumped Jiggly from my car, and finally set off...

At the top of our road, turned the indicators on, and it blew the fuse!!!!

Now some would take this as an omen that I was not supposed to go out, but not me, I drove back home, changed the fuse, checked the obvious, but found nothing, so packing a couple of extra fuses set off again...

Once there, I started by fitting a small consumer unit and then running the trunking and new wiring etc, leaving all the old stuff as it was for now.. I did hit a few snags, like not having enough trunking, and needing a spur feed for the pond pump, but luckily nothing major.

The old wiring consisted of a mains cable running from the house to a very old brown MK double socket. This socket then had a multitude of 4 gang sockets plugged into one outlet (ouch) and into the other socket was a normal 13 amp plug which had a length of 6amp twin core wire running from it through the wall to the outside toilet light...

Having got most of the new wiring done, and before I swap the feeds over, I just needed to fit a spur switch to join safely my new lighting circuit to the old toilet light wiring. I climb up the aluminium ladder, and holding on with one hand, lean over to grasp the plug, ready to pull it out the socket....

Suddenly, my hand flies back all of it's own, and the ladder launches away from the wall as I got a huge electric shock... Luckily, I did not come off the ladder, and apart from every bone in my body aching, I was OK.

Now, I know the wiring in this house is old, it was wired up back in the 70's by an electrician friend he knew. As Suz's dad knows nothing about electricity, he always got the electrician to do everything, and to be honest, I have in the past, met a couple of dodgy bits of wiring, but just pulling a plug out of a socket should not be a dodgy past time. On closer inspection, the fuse in the plug must of blown at some point in the long distant past, and instead of changing the fuse, someone had wrapped some fuse wire round the first fuse clip, then down to the second clip and wrapped it around that a few times as well, before putting the blown fuse back in to hold the wire in place!!!! To make matters worse, when they had put the cover back on, the two ends of the fuse wire had poked out the sides of the plug, between the top and bottom haves, right where you put your fingers as you grab a plug to pull it out.

I finished off, and got back home, but as the evening wore on, wow did I start to ache more and more... that was a pretty major electric shock...

So, to today.

I went out to check my car over, and found that my injector number 1 has a reading between 150 and 37 ohms, depending on if it is hot or cold. Looked to make sure there was no air in the fuel, and just for consistency, checked the MAF, but they are all ok, so looks like I now need to replace injector number 1... Not sure that was a better day than yesterday or not...

I'm an electrician by trade.

My wife is an FAW ( First Aider at Work).

This info is important! !!!!

Probably a bit late now, but...

If you receive an electric shock. You MUST call an ambulance to be taken to A & E and you MUST be on an ECG for 4 hours.

An electric shock disrupts the rythm of your heart and it takes 4 hours to settle back down.

At any point in this 4 hours you are at increased risk of heart attack.

Please, all take note.

I never knew that... Mind you with our hospitals round here it would take me 8 hours to be seen!!

I have worked with Electricity all my life, Switch mode power supplies, monitors and even 600v DC wave generators, which are truly evil when they attack, but I have always said when working with electricity, you should never get an electric "shock", as when working with it, you should always be expecting a "belt", so therefore it's not a shock if you get one...

This one got me hard though, as I felt I knew I was safe, no power on any part of the circuit I was working on, and plugs are safe, aren't they".

I will bear that info in mind should it ever happen again...

This was the info that my wife learnt last year on the new FAW course.

depends on the person, I have had thousands of mains hits as usually work live, always have, my father used to stick a fine wire into the coil lead on a car distributor, hold it with engine running and put his other hand on another person and then ask why they are jumping, including me as a 10 year old, he would not be showing any action a all, when he retired from the RAE Farnborough they presented him with a digital watch high tech led in those days, it worked great off his wrist but stopped within a few seconds of wearing it, mum could wear it no problem, it was too big for me, still got it, engraved on the back as well, tears now, sorry guys, Rick

I worked at Associated Octel Ltd at Ellesmere Port back in 1967. They used to make the Lead they put in petrol - Tetraethyl Lead.

I worked in the Production Laboratory (as a student) housed in Castner-Solvay section where they split Brine solution into Caustic Soda and Chlorine Gas using a moving Mercury Bed.

The Kellner-Solvay cells had Platinum Anodes with moving Mercury Cathodes the D.C. current was between 3.0 and 4.5 volts depending on production load and there was a huge Ammeter in the Cell Halls that read an average of around 30,000 amps !!

When taking production samples you were OK as long as your footwear was nice and dry but sometimes if the floor was damp with a leak of Brine or Caustic you would get a weird electric shock as unlike A.C. you found it hard to remove your hand from the Buzz Bars. You could not wear Toe Protector Boots as the magnetic field would grab your foot and it you could not break free !

I used to take my spanners and screwdrivers to work and leave them on an external Buzz Bar for a shift and they used to be really well magnetised come hometime.

I replaced the no1 injector today, with the £99 one I got off of Amazon. I went to use the new injector washers I got from Ebay, but they were too small, I now wonder if they are for the petrol model. So... I annealed the old top washer and reused it, but could not get the smaller washer out, so had to leave that as is.

So here is a question...

When I was playing with ECU Talk, i unplugged the MAF, to make a fault, and ECU talk showed it up, and then when I plugged the MAF back in, the Error cleared it's self.

Talking to MadMark, he said when he changed his injector, the Error code also cleared it's self.

So imagine how frustrated I felt, having changed the Number 1 injector, started the car, and the MIL light stayed on. with something aproaching mild panic, I plugged ECU Talk in, and checked the error messages. I still had Error code 34... I tried clearing the codes, and the MIL light went out... Result...

So, why do some codes stay and some self clear... and then why would MadMark's clear, but mine did not?

[Madmark]

They must be wired slightly different as didn't you say your obd plug was different. As soon as I started mine the eml light went out and ran spot on

[solarman216]

As I have found with all Nissan stuff there are variations, just some I can remember, to get the codes on a petrol you flash the connection, on the Mrs TDi you have to hold it on, on my TDi you flash it, many have been able to clear air bag light with various sequences, non worker with the Mrs TDi had to get a garage to do it, there are more but cannot recall at the mo, Rick

That sounds interesting, would of liked to seen that

Surprised you could feel 4.5 volts, my battery bank is high amps and 24 volt and even if I wet my hands and grab pos and neg cannot feel a thing, are you sure there was no higher voltage leaking in from some place? interesting environment nonetheless, Rick

.

think I foofed this up a bit, Rick

[Madmark]

Also on mine I maf goes down there's no ecu light but if I do paperclip test it brings up maf (code 12) I think it was
