Dealer doesnt know... im assumeing its a narrow band oxy sensor..


if its indeed a wide band sensor, can i pull an A/F reading off the obd2 port using obd2 scanning software??


Thanks

 

Yes if the scan tool supports OBD2 parameters; the O2 sensor is a federal required sensor reading.

 

And no, you likely have a narrow band (standard) O2 sensor, the only exception would be if you have a hybrid or a ULEV-certified engine. But, nonetheless, you can pull A/F readings from both.

 

?
actually i do have the ULEV certified engine, forgot to mention in original post, so i can pull wide band readings from odb2 port ??

 

With a scanner that can do realtime datalogging you can.

Starting in the 98-02 Accords with ULEV F23A4 engines, they used a wideband O2 sensor and a 32-bit Powertrain Control Module (computer) to cinch down on emissions by giving the computer more accurate information to adjust the fuel and spark supplies. Given that your engine is ULEV, you probably have a wideband O2 sensor, an easy way to find out would be the price. An OEM narrowband is usually about $100 or so and a wideband would cost $200+ from a dealer.

Wideband readings are usually a three digit (xx.x) number, which only the air number of the ratio is given, i.e. 14.4, which, in turn, would really be 14.4:1 or a perfectly balanced stoicheometric mixture in terms of dimensional analysis in chemistry.

 

thanks.. ill call dealer and double check on price, do you know of any good odb2 dataloggers off hand? was considering buying the auto enginuity one, it seems to be able to log o2 sensor voltage(lambda?) but not display an actual a/f ratio, does the ecu just see lambda and convert that to an a/f ratio?

 

They made the 7th gen V6 in a ULEV certified version?

 

I dont stink so... I cant find anything on it. It may have qualified though, because the J35A3 I have in the MDX is ULEV, but only has the window stickers for it.
