whitneybra Posted June 9, 2014 Share Posted June 9, 2014 Hi my 34 boost sensor has broken. Now im chasing a new one. I tried Ebay and the normal places so i decided to see nissan. They looked the part up and of course there is none. There system say the part is no longer made aswell but then says see part 22365-6p51a which is a nissan navara boost sensor which has the same plug and look very similar so my question is has anyone used the navara sensor.

75coupe Posted June 9, 2014 Share Posted June 9, 2014 I have the boost sensor from my s2 r33 if you want, i removed as part of upgrades... $30 +post or pickup Link to comment https://www.sau.com.au/forums/topic/444206-34-gtt-boost-sensor/#findComment-7307336 Share on other sites More sharing options...

That one above is the Map sensor for the ecu, I assume it has the same terminal setup, but are you after that or the boost sensor for the gauge in the dash?

I think its the Map sensor but written on the part is boost sensor which is kinda the same thing.

GTSBoy Posted June 10, 2014 Share Posted June 10, 2014 On R34s there are 2 MAP sensors. One is for the gauge and is usually on the driver's side of the firewall, and the other is for the ECU (to know when it has boost) and is more central. I don't know exactly where they are on R34s because my Neo is in an R32 and therefore I have the R32 gauge sensor (to the outside of the brake booster) and the ECU sensor is actually bolted to the top of the engine because there isn't an appropriate place on the R32 firewall. The sensor in the OP photo appears to be the ECU's boost sensor.

iruvyouskyrine Posted June 10, 2014 Share Posted June 10, 2014 It's not a MAP sensor in the typical term. The only function it provides is boost monitoring. If more than 14psi is seen it provides the ECU with a fault code. I believe that's the only fiction that it provides.

whitneybra Posted June 10, 2014 Author Share Posted June 10, 2014 i was under the impression it did more then just detect 14 psi and chuck a fault code. They found mine was broken when tuning and repaired it that was well over 12 month ago and now its fully f**ked and the car wont even boost with out chugging. i was running over 14 psi with no enging codes with a nistune.

GTSBoy Posted June 10, 2014 Share Posted June 10, 2014 With Nistune you can uncheck the monitoring of the boost sensor. Just like you can do the same for the TCS/ABS systems if they aren't present. You can't run 14 psi on a standard Neo ECU anyway, because it will chuck a wobble well before you get there anyway (R&R - and probably hit the TP limit from the AFM signal). So you need Nistune to be able to even think about it. So you would just turn off the sensor in Nistune anyway. But if you didn;t want to, you could always arrange for the equivalent of a boost T bleed arrangement to limit the amount of boost that the sensor sees. A simple self-relieving pneumatics pressure regulator would probably do the job. Set it to no more than 10 psi - that's all the sensor would ever see. Job done.

Ben C34 Posted June 10, 2014 Share Posted June 10, 2014 It's not a MAP sensor in the typical term. The only function it provides is boost monitoring. If more than 14psi is seen it provides the ECU with a fault code. I believe that's the only fiction that it provides. It does *something* else in the ecu. But what exactly is hard to pinpoint or use to tune. In nistune there is a boost duty table. It affects that which in turn affects fuelling. There was a guy that accidently hooked his up to the inlet manifold so it was reading vacuum and the car ran super lean and was un driveable.

GTSBoy Posted June 10, 2014 Share Posted June 10, 2014 The boost duty table is the wastegate control, I believe. Not fuelling. Link to comment https://www.sau.com.au/forums/topic/444206-34-gtt-boost-sensor/#findComment-7307794 Share on other sites More sharing options...
whitneybra Posted June 10, 2014 Author Share Posted June 10, 2014 All great information but my original question is to do with the replaceing of a broken unit with the navara equivlent that nissan say will work and is linked to now that the origanl unit is no longer made part number 22365-6p51A instead of the 22365-6p500. How would i go about making sure this part is working in the same way as the origanl.
