Customer Question
loses throttle response and won't...
My 2004 Maxima goes into limp mode frequently, where it loses throttle response and won't go over 2000 rpm. Sometimes if I shut it off, it will run normally on restart. It also has a "Weak throttle response" mode. Throttle body has been replaced four times, the last time with a new Hitachi. Also replaced accelerator pedal assembly. Each time a part was replaced, it ran fine for a while, but then went back.... Engine code involves voltage A ...voltage B...

P2135 engine code
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

That is a Throttle Position code.

Where did you buy these throttle chambers you installed?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
My mechanic put in remanufactured ones, I believe. I ordered the Hitachi from partsgeek
Customer reply replied 2 years ago
My mechanic also "repaired" the wiring to the throttle body wiring connector. I took it to him about 4 times for this problem
Customer reply replied 2 years ago
I have to go out for a bit. I will look for your reply and respond in about 20 minutes.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Oh, that could be part of the problem. After Market electronic throttle chambers never work right.

What was wrong with the wiring?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
I'm not sure about the wiring.
It was my understanding that the hitachi was identical to oem.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

No.. everyone thinks that, but they are not.

Can you find out what he had to repair as far as the wiring?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
I believe he found it wasn't making contact at the connector to the throttle body and spliced in some new wire.
I was thinking it might be a good idea to replace that connector and wiring with oem, but my local dealer said he couldn't get it.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

It was a problem with the connector?

Ask Your Own Nissan Question
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

I don't see connector issues to often on these cars.

I would see if you can get a throttle chamber from the dealer. When you get these reman Throttle chambers from auto parts stores, they use the OEM housing where it says Hitachi, but the internals are far from it.

Ask Your Own Nissan Question
Customer reply replied 2 years ago
I bought the hitachi new, or represented as new
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

where did you buy it? Can you return it?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
partsgeek.com
it has been a while...don't know if i can return...many months
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Yeah... I have seen cars come in to the dealer so many times with After Market electrical parts and had to put OEM parts in to correct issues like this.

I would say maybe around 6 months ago, a customer came into the dealer with a 03 Altima V6, where he replaced the throttle chamber and was still getting codes and couldn't perform the idle relearn. I looked at it, and saw it was after market. I put a OEM one on and took the after market one off, cleared all the codes, performed the idle relearn, and car has not been back since.

Is that the same code you keep getting?

Ask Your Own Nissan Question
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

I need to step out for a few. Can we continue this conversation on this in about a hour or so?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
I'm not sure, only read the code once.
okay, later
Customer reply replied 2 years ago
The relearn seemed to work fine...
Customer reply replied 2 years ago
But this same problem for about two years.... sitting unused alot
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Thank you for waiting.

How many times has it been to the shop for this issue? Has it been the same shop?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
It was in several times:
1. Replaced throttle body.
2. Then, wiring
3. Replaced throttle body.
4. Much later, 4th time...did entire Nissan diagnostic proceedure...replaced throttle body.
Then, later, I bought and installed the new Hitachi.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

So if the wiring and everything is good, then it sounds like it has to be the throttle chambers you are getting. Which does not surprise me.

How long does it normally take for the code to return once it's cleared?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
When new parts (throttle body, pedal) were installed, it would run right for a while, maybe a couple of weeks. Then, limp mode and cel.
Last was new pedal....the more I have driven it since then, the more often it is limping.
But, still runs right sometimes.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Why did you replace the pedal? Did you have a code for it?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Guy at parts store who read the code for me said that was probably the pedal.
So, if I order a throttle body from Nissan and same problem persists after it is installed, do you think they will take it back?
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

If you have the dealer install it and do the relearn, you have a 1 year or 12 mile warranty on the part and labor. So if the dealer was to look at this, and replace the throttle chamber for you, they would then be liable for this if the code returned.

But I know the dealer is expensive. But if the issue continues, wiring would need to be checked, and it could possibly be a Ecm issue.

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Yeah, I have been concerned about the ecm/ecu possibility...expensive.
After the second throttle body, I took it to the dealer. He said, "no problem, we will just reprogram it." $150 later, "your car is ready." Couple weeks later, same problem. Dealer say, "hey, not my fault, reman throttle body." So, I guess I need to find the next closest dealer...
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

See, they blamed the throttle chamber also. I would get a throttle chamber from the dealer. Have the idle relearn done and go from there. After Market electrical parts can't be trusted to work properly

Engine codes.com lists these possible causes for P2135 for '04 maxima:
- Faulty Electric Throttle Control Actuator (TP sensor 1 and 2)
- Electric Throttle Control Actuator harness is open or shorted
- Electric Throttle Control Actuator circuit poor connection
- Faulty Accelerator Pedal Position SensorRead more: http://engine-codes.com/p2135_2004_nissan_maxima.html#ixzz3k1Vai8zWI'm not seeing the throttle body, but I do see wiring and pedal. It is triggered by variance in two TPS voltages. Are the throttle position sensors in the throttle body?
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

The throttle chamber has all those tp sensors built into it. That link is incorrect to say that the accelerator pedal is part of the issue. This link I am giving you is right out of the factory service manual.

https://dl.dropboxusercontent.com/u/105565483/1d.jpg

You need to start by replacing the throttle chamber with one from the dealer.

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Is the wiring connector that connects to the throttle body available from the dealer already wired up? If so, I think I'd like to replace it before I take the car for service? Can you get me a part number?
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

It is not. It would only come with the whole EGI Harness. If you would like to replace that connector you would need to go to a salvage yard and snip it off a old harness.

If you have any more questions on this, please feel free to ask.

If not, and you're satisfied with my help, please Rate me. I hope I have provided you with Excellent Service.

Thanks Jay!

Customer reply replied 2 years ago
Thanks for all your help, Jay.
OK, I looked into the "rewiring" that my mechanic did. I removed the electrical tape that he applied from the connector at the throttle body to about 4 or five inches back. It looks like all of the wires, I guess six of them, are bundled in a ridged plastic "conduit." Then, inside of that they seem to be bundled in pairs inside of typical plastic insulation, with each member of the pair in its own colored insulation (green, yellow, etc).But, without stripping back that outer insulation any further, it looks like there is bare silver-colored wire, maybe braided, wrapped around the pair within that outer insulation, perhaps for shielding? This has just been jumbled up , leaving the last inch or two from the connector uncovered. It looks like this shielding wire from one pair would have been contacting that for another pair inside the tape he wrapped. Would you just tape it back up, wrapping all six as he did? would you try something like aluminum foil, or perhaps braided wire (from where, hardware store?) to rewrap the pairs and tapre them in pairs before taping the whole thing back up?
Customer reply replied 2 years ago
I bough a scan tool and I also have these codes: P0123, P0223, for high input voltages on A and B of TPS/pedal. And P1122
Customer reply replied 2 years ago
yep, sure looks like shielding. But must have terminated somewhere before connector, because the wires cross each other before it.
Not three pairs of wires, but a one (green, black) a pair, and a trio).

I will be online later this evening..

Customer reply replied 2 years ago
I wrapped each of the three bundles in Al foil and covered with electrical tape. Reset the ecu/ecm; normal operation for two days, about 6 trips of a few miles to twenty miles.
Recently it had been limp mode most of the time.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

You redid the shielded wire on the harness and it seems to be good?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Well, like I said, I wrapped them in foil and electric tape.
But, who knows...in a few days I may be back where I was.
Might be just unplugging and resstting that had effect.
Customer reply replied 2 years ago
It seemed every time a fix was applied (replace throttle body or pedal) it would be good for a while and then degrade.
Customer reply replied 2 years ago
Odd thing is I can see any splices or other fixes he did, he just peeled back the shielding as far as I could tell.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

i do know of some throttle issues. but normally it sets App codes. Lets see how the repair works out and let me know..

Ask Your Own Nissan Question
Customer reply replied 2 years ago
ok, will do.
Would you think peeling back that shielding wire for a couple inches from the coonector would have any effect?
Another odd thing was a LOT of like...silicon gel inside the connector. Conductive paste maybe? I scraped it out with screwdriver blade.
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

That silicone keeps everything tight together with in the harness.
