Just getting back into the Civic game after 10 years. A slight detour with a RSX-S, S2000, and NSX-T. Last week I purchased a 1997 DX Hatchback with a LSVTEC and GReddy Turbo. The LSVTEC is built with a 1999 B16a Head, B18B1 Block, ITR P73 ECU, and what I believe is a 96-98 DX Harness.
I knew buying the car, that it was not running at its fullest potential. The guy I bought it from only had it for a couple of months and bought the car in its current state. No useful information was given to me from him. I still have no idea what it has for internals.
I noticed the Check Engine Soon light did not come on, and to no surprise, I found the bulb missing. Plugged it right in and there it was. Originally, it was running on a P75 LS OBD1 ECU with a jumper harness, but again, I have since changed it to a ITR P73 OBD2a ECU. I was able to retrieve 3 codes, P0135 O2 Sensor, P0325 Knock Sensor, and a P1337 Crank Fluctuation Sensor. For the time being, I will ignore the Knock Sensor code as I will be getting a Hondata soon. P1337 was fixed when I performed the CKP Wire mod (connected C1 and C4, then C11 and C14). Now for the O2 sensor.
My car is OBD2 running a OBD2 ECU, just wondering if there was a difference in O2 sensors. If there is a difference, what year and car O2 sensor should I get. Do I go with a 1999 Civic Si B16a o2 sensor to match the head? B18b1 O2 sensor to match the block? 1996-1998 to match the Engine Wire Harness. ITR O2 sensor to match the ECU?
Thanks
