Herb Posted May 19, 2011 Share Posted May 19, 2011 (edited) are the 2 sensors for Jspec NA any different? my toyota garage tells me that these are different, they have even different part numbers/prices. is that possible or is it just a mistake of my garage?? i think the US-Spec has two different ones!? regards, herbert Edited May 19, 2011 by Herb (see edit history) Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted May 22, 2011 Share Posted May 22, 2011 I've just cleaned mine, as I'd read the guide and figured it wouldn't do any harm. My MPG hasn't been that great either. As per the guide, I soaked the 02 sensors in lemon juice, then '3-in-one Professional heavy duty cleaner degreaser' and finally with some carb spray. I immediately noticed an improvement with the idle (which was a little high before) now idles at exactly 1000 rpm for a few minutes at startup, then drops to exactly 600rpm and holds solid. I'll get some MPG figures over the coming weeks. Would I benefit from resetting the ECU? Also, I started the car up with the 02s removed, sounded like a Spitfire Quote Link to comment Share on other sites More sharing options...
Herb Posted May 22, 2011 Share Posted May 22, 2011 I just ordered a pair of new denso sensors..... Quote Link to comment Share on other sites More sharing options...
Konrad Posted May 23, 2011 Author Share Posted May 23, 2011 Would I benefit from resetting the ECU? It does not harm to reset ECU, only remember to leave it for few minutes without revving during re-learn process. Quote Link to comment Share on other sites More sharing options...
Missile Posted May 23, 2011 Share Posted May 23, 2011 Also, I started the car up with the 02s removed, sounded like a Spitfire I really wanted to do this, but my sensible side said no. Wish I had now... Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted July 14, 2012 Share Posted July 14, 2012 does anyone know if WD-40 would be ok to clean the O2 sensors with after they come out of the Lemon juice, or do you need to get specifically brake cleaner, and if so, would something like this be ok? http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_categoryId_228374_productId_249510_langId_-1?cm_mmc=Shopping-_-Google%20Product%20Search-_-Bikes%2FBike%20Maintenance%20%26%20Tools%2FBike%20Cleaning-_-Muc-Off%20Disc%20Brake%20Cleaner%20400ml&source=shopping#tab1 Quote Link to comment Share on other sites More sharing options...
LOGIE Posted July 14, 2012 Share Posted July 14, 2012 im sure it will be fine but Halfrauds own branded stuff will prob be slightly cheaper. Let us know how you get on as its something ive never got round to doing. Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted July 15, 2012 Share Posted July 15, 2012 Why does it have to be brake cleaner, could it not be something like methylated spirits? As I know you can clean brakes with the methylated spirits, just wondering as I have some methylated spirits at home, but no brake cleaner, weird question I know.

thetrashcanman Posted July 26, 2012 Share Posted July 26, 2012 Anyone know how long it should take for the denso O2 sensor to come from ROCKAUTO? Quote Link to comment Share on other sites More sharing options...
markg1150 Posted July 26, 2012 Share Posted July 26, 2012 does the lemon juice have to be fresh or will cordial do?? think ill give this a bash at the week end she has been drinking a little heavyer lately. but i have just fixed the air con Quote Link to comment Share on other sites More sharing options...
Geo Posted July 26, 2012 Share Posted July 26, 2012 Anyone know how long it should take for the denso O2 sensor to come from ROCKAUTO? Ross's sensors arrived within 4 days im sure. All fitted and working a treat. Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted August 3, 2012 Share Posted August 3, 2012 Ross's sensors arrived within 4 days im sure. All fitted and working a treat. Blime, mine took over a week, although they did have to clear customs, mine are also working great and does anyone know if its a good idea to reset the ECU? and if it is how to do it?

Pull the negative lead off the battery for a few mins, then reconnect, start car, and leave to idle for a few mins, then go for a gentle drive.

C12MMO Posted October 18, 2012 Share Posted October 18, 2012 If I'm being daft, please tell me. What is the correct denso part number for a 1999 j-spec N/A O2 sensor. On rockauto.co.uk I've narrowed it down to p/n 2344630. Before I buy them, is this correct?? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
locutus9871 Posted January 2, 2013 Share Posted January 2, 2013 (edited) Call me stupid too as yes I'm female but do all my own Mechanics on my Supra but was looking at getting Universal one wire O2 sensor's from my local Autofactor's as have a trade account as they're only £11 each. Then all i Have to do is cut the connector plug off the old sensors and solder them onto the wire and heat shrink. Sure this is ok but please let me know if this is not a valid thing to do !!

schemauk Posted June 10, 2013 Share Posted June 10, 2013 Doing this right now, the sensors are currently sat in a pair of 'Purple Ronnie' shot glasses! Not sure how dirty mine were as I had no way to gauge it... They didn't look terrible, but nothing wrong with leaving them in a small glass full of freshly squeezed lemons overnight Also took it as an opportunity to freshen up the heat shield, and clean up a few other bolts around the general area by scrubbing them down and spraying black. Will reset the ECU as above when I stick the sensors back in. An easy job to do that can only do good at the end of the day! Quote Link to comment Share on other sites More sharing options...
