matth76 Posted July 16, 2009 Share Posted July 16, 2009 Hi A few weeks ago my engine management light came on (was a yellow colour) but the car drove fine. Went to a garage who read the code and it was p2135 which is "Incorrect electric voltage to throttle position sensor". The garage also told me they thought my exhaust backbox sounded as though it was blowing slightly. Anyway the cleared the fault and for the last month it has been fine. Today I parked in a car park and when I got back and started it the engine management light was back on (again a yellow colour) and this time the light saying the traction control was off and the symbol to the right with car "skid" marks. The car would hardly rev and not go much more than 30mph and up hill it would crawl along much slower. Occasionally it would rev very high. I assume this must be what is called "limp mode". Is this correct? When I got to some traffic lights I turned the engine off and on again the traction control lights had gone out and the car would rev and drive normally again, however the engine management light was still on. Has all this to do with the initial fault I experienced a few weeks ago? Is it ok to drive my car (it is driving ok now since turning it off and on although the light is on)? Oil and water temps absolutely normal. Thanks for any help and info. Quote Link to comment Share on other sites More sharing options...
Tony@Abbey m/s Posted July 16, 2009 Share Posted July 16, 2009 Sounds like it has either a throttle pedal and throttle butterfly voltage supply problem. We have had this problem on our mule 350Z JDM car , tried a throttle switch and a butterfly without any luck. We managed to trace the fault to a broken wire in the loom pretty simple job to re wire. any questions please feel free to ask away.

matth76 Posted July 16, 2009 Author Share Posted July 16, 2009 Thanks Mark. Looks like I'm going to have to get my local specialist to isolate the problem. Car is only just 4 yrs old so this is all really surprising on such a newish car. Does anyone have the process of clearing the light manually (without a code reader) - something that I can do myself without any tools?

BladesGrant Posted July 16, 2009 Share Posted July 16, 2009 There is an ECU reset guide in the guides section. Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted July 17, 2009 Share Posted July 17, 2009 Thanks Mark.

matth76 Posted July 17, 2009 Author Share Posted July 17, 2009 Cheers guys for your help. Will hopefully have it booked in to GT Art when they can get a response from Nissan on the parts required and poss costs. So far touch wood car has been fine (still drives very quickly), drives fine just has engine management light staying on (same yellow colour). Only thing that seems to be present (and has been the case since the light came on last time is the exhaust is very slightly louder, like it is blowing as suggested. Sounds a bit better/sportier than normal to be honest but was wondering if this could have any affect on what has happened - ie if an exhaust system is blowing slightly could it cause a fault like this? I assume it's fine to drive the car normally in the mean time? Thanks for the help so far. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted July 17, 2009 Share Posted July 17, 2009 Once you have your issue resolved then you may wish to fit spacers to the rear sensors. Plenty available so no rush. If required just pm for details. Quote Link to comment Share on other sites More sharing options...
witstu Posted July 17, 2009 Share Posted July 17, 2009 What are the spacers to rear sensors? Quote Link to comment Share on other sites More sharing options...
D12BHP Posted July 17, 2009 Share Posted July 17, 2009 I have had this problem on numerous occassions, like you said turn the car off and on and it goes away. Reset the ECU and it goes away. But envitiably it comes back! and the last time it did not go away... it turned out to be a Control Unit, the 350z has number of these to control the electronics from Door mirrors to traction control. Dan from Advance Motorsport fixed mine - give him a shout let him know Sonney advised you call him with Grey 350z.(hes got my car at the moment) 01327 857 577 Good Luck Quote Link to comment Share on other sites More sharing options...
Posidrive Posted July 27, 2009 Share Posted July 27, 2009 Is there a standard ODB-II port anywhere? I have a code reader that I used to use with mu old Subaru and I'd hate it to be redundant now. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted July 27, 2009 Share Posted July 27, 2009 Is there a standard ODB-II port anywhere?

Mark@Abbey m/s Posted July 27, 2009 Share Posted July 27, 2009 If you go with a Rev up remap you can turn the error code of for the rear lambda sensors , which is especially good for when you remove the Cats and fit test pipes. Mark Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted July 27, 2009 Share Posted July 27, 2009 I had this on mine, ECU reset sorted it, but mine turned out to be low on engine coolent... Quote Link to comment Share on other sites More sharing options...
