Nissan Sunny 2007-2010 P2122 And P2127 No Acceleration. by GAZZUZZ(m): 9:03am On Oct 28, 2018
Driver calls in, states vehicle RPM is @ 1.7rpm steady and he's unable to drive the car. I tell him to take out the battery and leave it for a few minutes and try again.

trys it again same thing.

Driver scans vehicle, scan reveals P2122 and P2127 the codes are permanent codes.

it's a weekend and I am very busy so I ask him to find a way to move car down to the workshop from ajah (law sch).

he finds a way (Don't know how he did it) and sat morning car is in front of workshop.

I decide to do a quick 15min assessment of the associated symptoms

Plugged Scanner scanned...... codes.. www.nairaland.com/attachments/8034971_img201810280636019_jpeg09a2fbc44ad4b02f2594b284c6befecd

Clear codes, but re-scan and same codes pop up again. Meaning code is permanent.

So I take out the Throttle pedal and Inspect the potentiometer, I was hoping to find fluids or corrosion or a damaged contact inside. (Sorry no pics for that), found nothing.

put it back together, adjusted the contacts a hoped it would start working again (fluke things grin ) same thing, no response from accelerator pedal with engine running. cry

My 15mins was up, I had a wedding to attend, so I abandoned it and headed home.

Church wedding over, sitting in reception, but my mind is still on the nissan. I receive a call about a client who wants to pick up his vehicle, but they can't find the keys, I tap my pocket and the keys are with me. sad leaving Mrs Gazzuzz in reception I head back to workshop (5mins drive) drop off key, and did another 15min check on nissan again. This time live scan, checked input voltage when pedal depressed, readings varied according to pedal positions (meaning pedal was fine)

But output readings on throttle body when pedal depressed were static. So I just assumed a faulty Engine ecu undecided

Next plan was to find someone who had conquered this error and find out how it was conquered.

Placed an Sms to my Oga patapata of Nissan, I was very vague in my explanation but His response was "you might have to change the unit"

next I called my Oga in Nnewi he said same thing, that he just solved one same way.

I was having hope small small... next thing phone rings..... Its the Mrs.

I abandoned ship again. Went back to reception and my people were ready to go. On my way home, I called another Oga in PH, he said it's a wiring problem check harness, said he had seen similar issue and it was a wiring problem.

my head is now full.

5:46pm I message Uncle Autoelectng gave him a brief description of the problem, and asked if he had experienced same type of issue he said yes, but it was a transmission related fault. He promised to get back to me.
ill tell you one thing about Uncle, he likes all the info. Model year, engine type, production year, transmission type, etc, last last I sent him the vin and messages were quiet for a while.

In the morning 5am I opened my messages and saw a video link Autoelectng sent, it was not in English, but I understood "mechanic" (it's a universal language)


https://www.youtube.com/watch?v=Kn992Ci8UyE

His message was sent 2:41am.

5:52am I was out of the house straight to the workshop.

This is now a full explanation of what the issue is and how it was solved.

There is a rubber stud at the base of the accelerator pedal, with time it disintegrates (carefully looking at the floor mat you will see the remains)

www.nairaland.com/attachments/8034947_img201810280627127_jpegd96798d6a4c03ada9159d9bc39f738d9

when this happens, the app sensor on the pedal gives off a higher than usual resistance @ idle. The engine ecu has set parameters for the operation of the throttle pedal sensor, and any slight deviation from parameters throws a circuit code and disables the function of the pedal (That's why we love toyota grin).

www.nairaland.com/attachments/8034948_img201810280628146_jpegb04d04f419d21a4d2bf74866b55e6961

Looking closely at the pic above you will notice a large hole with no rubber stud top left and pedal resting on base (you need to understand "mechanic"wink

First plan was to test an see if this would work.

Got a good old used slippers (saving technicians since 1801)

www.nairaland.com/attachments/8034950_img201810280629168_jpeg9a6a0e821173841a792c338c3832b419 .

pinned it behind the pedal base, cleared codes and for the first time since this problem started, I went back to read codes and they were gone shocked

www.nairaland.com/attachments/8034972_img201810280634321_jpegcc227ba298ab28a648c9cd93e10873f3

Started car and pedal worked perfectly, idle back to normal.

So I say to my self, how will I ensure this 1801 saver remains in place without falling? Or should I just re-design the pedal?

I vex and brought out my welding machine and a 10mm nut, welded it to the base of the pedal and installed a screwed a 10mm bolt in place to allow pedal rest on bolt grin this was more like killing an Ant with a sledge hammer.

www.nairaland.com/attachments/8034982_img201810280645023_jpegbe823ccb87031fe7245ca01865226607

Looked good and firm, tested it and it worked, but long term, metal to metal contact without any lubrication will cause a small dent that will grow, it might take several years, but it would happen.

So I decided to use the rubber stud, and place it inside the 10mm bolt, it was a very firm fit, I had to pull really hard and finally it sat perfect, not requiring glue to hold it in place (but I sha put o!)

www.nairaland.com/attachments/8035014_img201810280630215_jpegcf7928aa3f6421d6f88ec0ac64f5eb75

Tested and it worked perfectly. Phone rings it's wife : Hello baby you have the key of the IX with you? I tap my pocket angry have to run home cheesy

Thanks for viewing.

I guess it's because of such inexplicable nuances that Nissan will always warn to never replace the sensor but the whole peddle assembly.

@ GAZZUZZ your understanding of mechanics and electrical systems is very apt .

If one understands that sensors are mere fabricated devices leveraging on conversion of mechanical or physical variations to electrical pulses for its detection, it'll be very easy to troubleshoot the problems.

Yesterday, I parked my 2007 VW Passat and discovered one of the dashboard warning light was on . I googled the symbol and it was "fuel tank cover off " grin I wondered when the midnight street urchings car Vandals started stealing tank cover .
I opened the lid and discovered it was well screwed in place. I had to unscrew and screw it back any the warning light went off ... It was a case of two electrical conductors not making correct contact... Sometimes all these sensors grow rusty and malfunction and one might start treating a false alarm forgetting that the whistle blower might be the culprit. Thank God u didn't change the unit grin

As long as you don't go above the 2003 model, you'll be ok. The Xterra is a work horse. I used mine for 4 years and I only carried out the routine service required. The parts are fairly cheap to get. I'll also recommend getting the ones with 'auxilliary' gear.

Your analogy does not exactly cohere with the case in question here. All that happened was your fuel filler lid was not properly mounted. (And this is a common enough scenario). If it had been defective and you had found a way round it you could well beat your chest for beating VW to their tricks! The pedal assembly had become defective and an improvisation was made. If this was to serve beyond a temporary expedient, then as the term goes on this board, it’s Kazeemization. The ideal is to replace the assembly and return the mechanism to factory specs (hm…that phrase sounds recently familiar).

fastest shortcut to being a very good mechanic...

get an extremely used and abused naija vehicle (rare brand) and make up ur mind to fix it......

PS have enough spare time on ur hands or resign from ur current one.
