Nm35 Throttle Body Replacement

[loymclure]

recently my TB started playing up, while i was driving i would lose all power and not be able to accelerate I also noticed that my revs had lowered to near 0 when i started the car. Some days when i started her up same thing id get a engine light and have no accelerator. Speaking to craig he said look at the Throttle Body.

after ringing up numerouse places chasing a genuine part i was told

A. There were none in the country

B. and Quote from email http://www.nissanparts.com.au "The throttle body is $2118 available out of japan."

after a bit more googling i found these guys

www.PECONLINE.com.au

and they did it for

"Item: Nissan 350Z Throttle Body (042)

Total: $286 incl. delivery"

if any of you need this part try these guys.

It was also a very simple swap out job no learning no messing around.

Good to know, did you run the part number thru Jesse streeter by any chance?

[loymclure]

lol nah, who is Jesse Streeter?

[Commsman]

I suppose you did all the cleaning etc first?

And I also assume the new one fixed your problem?

Reads as though it was an intermittent fault. Have you had it in long enough to make the 'all fixed' call?

[loymclure]

nah not sure if its fixed the issue. lol was there supposed to be heaps of cleaning involved? coz all i did was remove the old one and put the new one in. I took it for an hour drive and couldnt get it to fault?

[Commsman]

Lol, a lot of TB issues are fixed by cleaning it. Was wondering if you tried cleaning first, before replace it.

I hope it has fixed your problem though.

[loymclure]

lol man honestly im so lazey when im not at work, i just cant be stuffed trying to fix stuff, id rather just buy a new one and know itll last another 10 years before i have to replace it again (knowing i wont have the car for another ten years also helps).

ahhhhh i cant lie with a straight face once i replaced it i opened the other one up by cutting the pop rivets off to see whats inside. What i noticed inside is, i don't think cleaning out will fix any issues, there is only three gears, a DC motor and a Spring. if there was a sensor of some type yeah cleaning mite aid this but its pretty much mechanical besides the DC motor that has a + and - terminal. It has no other electronics.

I did a cable throttle conversion and tuned it with the emanage, it worked well, you will lose variable cams though. Very laggy.

[joshm35]

Upgrade cams, cable throttle FTW

[loymclure]

Yeah issue happened again this morning, started car, had no accelerator with a solid engine light. turned ther car off and turned it back on every thing was back to normal took it for a drive down the street and while i was driving (about 60 km/h) same thing happened engine was still on engine light apeared lost my accelerator, slipped it into neutral turned the car off, turned it back on and engine light went away and car was working again.

any ideas?

[Daleo]

What is the fault code?

[loymclure]

cant get the fault code? dont have a code reader thinger and if i turn the car off it resets its self.

[scotty nm35]

The codes are stored in the ecu, even when you restart the car. Sounds like the pedal sensor.

[loymclure]

yeah i just realised this thanks scotty and dale, had a go at it and got two codes, (thought you needed to get the code when it was happening)

P0121 Throttle Position Sensor/Switch A Circuit Range/Performance Problem

P0235 Turbocharger Boost Sensor A Circuit Malfunction

Car idles fine when its cold and warm?

not sure what the boost issue is, not running any boost controllers. last thing we did to it was swap the turbo for Hi-Flow and put in a boost guage, also i think i have one of your presprung waste gates scotty ? none of these should be throwing a code yeah ?

[scotty nm35]

It will most definitely throw a code, as the wastegate will now hold 15-16psi and the car when cold is expecting no more than 7-8psi. You can perhaps just pull the plug off the boost sensor and stick a bung the hose to stop that one.

The other code is the same one I get, it is saying the throttle pedal sensor isn't within spec, and it limits the throttle. You can actually still drive like that, but you have to put your foot to the floor to accelerate a little. Do you have cruise control or a throttle controller plugged into the pedal harness? Otherwise you will need a new pedal assembly to replace the sensor, $220 I think from Amayama or $400 from Nissan.

[loymclure]

I have Cruise controll, i just unplugged it and will drive it round for a bit to see what happens. ive had the cruise control for ages, this fault has only recently started happening. ill buy the new pedal assembly and throw it in. do you have a part number for us please? cheers

[loymclure]

since the cruise control has been unplugged she seems to be running ok... 2 hours of driving and nothing. not holding my breath but will just have to see what happens.

[bigkevracer]

Funny, sounds like my fault. But mine doesnt present itself on the stock ECU...

[gptech]

Hi, I know this is old but what was the end cause of the OP's problem?

As my wife's Autech is doing the same thing and throwing the 0121 error code and yes it has cruise.

Thanks,

Grant.
