can't communicate to ecu

[piggychu]

hi all

i bought a 350z few months ago,the only mod is a blitz induction kit and a 5zigen cat-back system . when i bought it the CEL is on already ,the car drives very well nothing wrong with it so i dont bother .few weeks ago the car start goes wrong , it can't drive to high rev ,it seems been limited the rev .

Then i took it the nissan dealer to check it , the mechanic said they can't communicate to the ECU so they can't do anything with it . and the other mechanic said he had plug in his laptop and it come up the result is o2 sensor but not 100% sure which one ( that's 4 o2 sensor in total )......the only thing they sure is the car was running safe mode.........

 

can anyone tell me any 350z specialist near oxford ?

and where can i buy the o2 sensor apart from nissan ( they charge £200+vat each )?

 

Thanks for your help

You have Jez@Horsham in Chieveley or a bit further and you have Mark@Abbey M/S. Both will be able to sort you out and are traders on here, give them a search

 

O2 sensors

[narcotix]

Is it a UK car or a JDM Import?

 

I know some ODBII readers don't work with Imports ...

[Jez @ H-Dev]

We should be able to help. We've got O2 sensors in stock too

 

Give me a call / pm if you'd like to chat about it.

Have you tried ECU reset? You can also get the codes

It's in the guides section

Quick reset tip.

Disconect the -ve battery terminal for at least 10mins and depress the brakes pedal fully to discharge the capacitors which will comopletely reset the ECU and evrything else on the car then reconnect the terminal and job done

If that fails(unlikely) then i'm afraid you are up sh%t creek and deperate for a paddle

Couple of things:

 

Check all the fuses under the cover next to the Battery.

 

Also check all the fuses in the fusebox.

 

I presume the car still runs? If so it can't be anything major.
