mellonman Posted January 30, 2012 Share Posted January 30, 2012 i have been trying find a decent lambda sensor to fit in my single turbo down pipe and need a non flage type and the n/a has this type denso 234 4626 pre cat sensor but would it work with the tt ? it still is a 4 wire sensor so was thinking it would be better then the £30 ebay jobbies but would like to know if anyone knows if they fit or what one i can get to fit Quote Link to comment Share on other sites More sharing options...
FOSTA Posted January 30, 2012 Share Posted January 30, 2012 If its the same connector and has the same wires then I can't see why not mate. but don't take my word for it as im not a 100% Quote Link to comment Share on other sites More sharing options...
mellonman Posted January 31, 2012 Author Share Posted January 31, 2012 im not worried about the conector i have the original that i can use if it dont fit, i wanted to make sure it was a 0 -1 v narrow still and would at least last more then a couple of months,im starting to luck out on this i thought it would be easy but there are so many types and all i want is a universal fitment that will last Quote Link to comment Share on other sites More sharing options...
Nic Posted January 31, 2012 Share Posted January 31, 2012 The NA O2 sensors have just a single wire to the plug, the TT O2 sensor has two wires. Quote Link to comment Share on other sites More sharing options...
mellonman Posted January 31, 2012 Author Share Posted January 31, 2012 (edited) i thought wrong then stock gte http://www.densoaftermarket.com/catalog/product_image.php?id=234-4514&part=o2sn and stock ge http://www.densoaftermarket.com/catalog/product_image.php?id=234-4626&part=o2sn all from this page might be a good find http://www.densoaftermarket.com/catalog/catalog.php?part=o2sn Edited January 31, 2012 by mellonman (see edit history) Quote Link to comment Share on other sites More sharing options...
mellonman Posted February 24, 2012 Author Share Posted February 24, 2012 (edited) okay thought i better update this one as i went ahead and brought the 234 4626 denso direct fit sensor and well it has the correct plug and fits well, i can tell the tt owners that this n/a sensor works in the tt the only thing with is the voltage must be a little different as the afr now between 14.3 - 15.0 where as the tt sensor was more close being 14.6 - 14.9. so at least it will stop any leaning out and will save petrol from not having the sensor there. anyway thought i would say these are £60 from the u.s.

The reason you're seeing a more widely varying AFR, is down to the sensor not being heated, so its not kept at optimum temperature, both sensors are the same apart from the TT type being heated. The ECU is just having to work harder to try and keep the AFRs around stoic, and i suspect false economy in the long run. Quote Link to comment Share on other sites More sharing options...
mellonman Posted March 25, 2012 Author Share Posted March 25, 2012 yep the sensor is still working fine, its still around 14.5 - 15.1, some times once warm and restarting the car it goes lean 16.0 at idle for about 15 seconds so would be in line with what ricky is saying, im not sure why as it should be a heated one though.

chazuk Posted March 25, 2012 Share Posted March 25, 2012 Thats good to know I ordered the same one, saves the hassle of fitting the toyota 02 flange to the dp when I already have a spare screw type hole I am pretty sure reading up on Denso if its a 4 wire the 2 white wires are the heater wires?

mellonman Posted March 26, 2012 Author Share Posted March 26, 2012 yeah its a 4 wire 2 white 1 blue and 1 black , but i do agree there is some heating issues this might be because i had to extend mine as it was for the single turbo conversion but it works well enough for me Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 19, 2012 Author Share Posted June 19, 2012 just an update this sensor is still going strong car made 520 bhp 510 ftlb its done about 5k maybe Quote Link to comment Share on other sites More sharing options...
