I recently bought and 2000 itr with (b18a) ls/vtec turbo. The car came with a p73 ecu (OBD2 ECU) with an obd1 wiring harness conversion. To make the story short, the MIL light came on and I manage to retrieve dtc code 1 which is the primary o2 sensor. Since the wiring harness is obd1, there was only one 02 sensor being used, located on the downpipe. I was just wondering if anyone can give me advice on which year and model should I look for when ordering the o2 sensor? Any help guys, I try to search but could find that much help on the topic.

 

Not only did you buy an ITR with an LS engine but it is using a stock ITR ECU on an LS/VTEC Turbo setup?

 

From what I had heard, the previous owner use a hondata also. Just wondering if you which year and model is the o2 sensor?? U think I should look for 02 sensor for 90-95 ls model??

 

So you are saying it has an ODB1 engine wire harness? Either way, this question is better suited in the hybrid forum.

 

Thanks, let me try the hybrid forum. Thanks for ur help.
