Do all 1nzfe cars have the same codes?

[blxebxrry]

I've got a scion xB and it has the same engine as the Yaris the 1nzfe, you guys seem more active than the xB forums so I figured I'd ask if the codes are the same

we've narrowed it down to the evap purge valve but everything I was told to check checks out and nothing looks wrong with it, before I get a new one I wanted to ask here.

I replaced mine a couple of years ago or so when I was chasing some ghost faults (come to find out later that the ODB II reader I was using was bad). Then I used my buddy's fancy ODB II reader (tablet style), and if I remember correctly P0441, 442, and 446 where the only ones that showed up, which pointed to the evap purge valve. I was scratching my head, because I had just replaced it. I didn't want to spend another $70, so I bought one from EBay for $12 and the fault went away. Been trouble free since, and actually I just did my emissions check this past Saturday, and passed with flying colors! :biggrin:

yes in fact most toyotas share codes

replace the purge valve thats mounted up on the intake pipe, 10-1 odds are its whats failed, clear the codes then go drive at 46-63 mph for 3-5 mins that should do the emissions readyness check and tell you if youve fixed it or not

honestly i grabbed a pair of used units for 5$ at a wrecker and tossed 1 on my XB-2 and it solved it...and it tossed that same stack of codes
