Throttle won't go above 20%

13_370_13

Im having the same issue with my 2013 370Z with no mods. Seems to really be an issue on the 2013's from all the research ive done. I haven't had a chance to clean my throttle bodies to try and diagnose the problem due to the weather and the car is stored for winter so there is no getting it out to see how it runs afterwards. Ive tried shutting down the car as some has stated that it would temporarily fix the problem but that doesn't work either. Also it does happen after my car has sat for a long period of time. like 10 hours or more.

please keep us posted, i think its time i also wrote to nissan consumer affairs, ive had this issue for about a month now. First dealer said it was the throttle bodies(both, yeah right...) its been at a second nissan service dealer for 3 days and they havent been able to find the problem yet. Then nissan wonders why we prefer to work on our own cars instead of taking it to them

I think it's time to get a little more methodical about this so we have some data to talk to Nissan with. Being able to say that many others have this problem will help get this work covered by Nissan.

If you have experienced the following symptoms:

• Throttle response limited, but not RPMs, and
• Stored/Pending codes P0101 or P010B - Mass Air Flow "A/B" Circuit Range/Performance

Please reply to this post with the following:

• Year
• Miles
• Nismo/Non-Nismo
• 7AT/6MT
• Intake mods
• Comments on when it happens, how often, work performed to fix it, etc.

• 2013
• 35,000 miles
• Nismo
• 6MT
• Stillen G3 intakes with dry filters
• Only happened once and went away after restarting the car. Both codes were pending, but no CEL.

Good idea, Brad.

Ill have to check with the dealer if they found pending codes, supposedly they didnt when i asked about 2 days ago, car is still in the shop. I believe my car isnt actually limited in RPMs, but seeing that when i stepped on the gas, it did limit RPMs between 2.5-3.5 rpms, depending on gear or RPMs at the moment i stepped on the gas, i didnt want to push the Z hard and risk damaging something else.

-Had the pending code, no CEL. So I had the Throttle Bodies cleaned, Seafoam ran through the system, and the MAF's cleaned with specific MAF cleaner. Throttle body cleaner can work but can cause the seal for the MAF to swell so I opted for the latter MAF cleaner. Issue hasn't popped up again since but only time will tell.

Update, had the previously mentioned resolved and hasn't resurfaced since. Pending code hasn't come back either.

AAM S-Line Mid-pipe. K&N drop in filters.

I have this problem repeatedly. No rhyme or reason as to the onset, but my quick remedy is to unplug the passenger MAF (P0101) for 10-15 seconds, blow out the connectors, ( i suspect there is an intermittent connection to the MAF sensor at the plug) and then replug the passenger MAF sensor. The Z starts and runs normally then. No limit to throttle opening or fuel delivery. The problem does abate but the pending code remains and needs to be cleared.

How old is your battery? I had the same issue in my 2010 nismo last summer.It would do it to me after the car sat for a couple days. I brought it in and the dealer showed me the battery was very weak. They put a new one in and it never did it again. So get the battery checked itf you have not already and all the best of luck

I just had this happen to me last week (limited throttle response) and took it into the dealership for diagnosis. The car was running horribly, but no check engine light. The next morning was when the check engine light showed with the code P0101. Luckily the dealership told me everything was covered under warranty. (but I see this wasn't the same for some others) They flashed the ECU for me, and so far so good.

My fix has resolved the issue. Still issue free since performing fix.

Mine hasn't come back since doing almost nothing...so I'm wondering if it is just some sort of glitch on startup.

I purchased a 2013 370Z at the end of February. The car is a Touring with the Sport package, manual transmission in excellent condition with 36000 miles. The second day of ownership the ses or mil light came on. I wasn't too concerned until it went into limp mode a couple of days later ( didn't have any power over 2500-3000 rpms ). I took it to the shop and the codes indicated the MAF sensors were faulty. Replaced the sensors, all was good....for about four days. The ses light came back on wtf!!?? Apparently there is a tsb #15-058 for codes P0101 and P010B for all 2011-2015 370Z coups and roadsters which is an ecu re-flash and should be covered under your emissions warranty. I just had mine done today, hopefully this fixes the issue.

My 2013 has the same problem. Sport package w/ manual trans and no mods. Codes that showed was P0101 P010b P0101 pending P010b pending. Have yet to clean the maf sensor and throttle bodies

When I do my oil change next month, I'm going to clean my MAF's and throttle bodies then too. I've had the OP's issue for 2 months now. It's happened 4 times now. I took it to the dealer and I didn't have any CMDTC's. I"ll report back if the issue is fixed or not when I clean my MAF's and throttle bodies.
