So I recently bought a b18 swapped 92 hatch off a friend of a friend and am having a hard time getting info on the car so I can fix it; other info p75a01 ecu, no idea year model b18. I currently have 2 check engine lights in on the car, code 7 and code 41.
Code 41 for the o2 sensor: The car doen't even have an o2 sensor hooked up. What part number is required to install an o2 sensor to clear this code? There is a 2 wire connection to put one in just a little lost as to which one I need.
Code 7 for throttle: do I just replace the throttle position sensor?
Ideas on the above would be greatly appreciated, here is the motor:

 

still looking for some help

 

Your local parts store.

 

look at the block code, if its b18a1 then go to the parts store and get an o2 sensor for 90-93 ls integra, if b18b1 then 94+ ls integra

 

'90 - '91 Integras are OBD0, '92 - '93 are OBD1, they use different O2 sensors.

'94 - '01 Integra is a safe bet, but any 4 wire OBD1 honda O2 sensor will work, the only difference is the length of the wire between the plug and the sensor itself. Buy an NTK or Denso sensor, stay away from Bosch.

Also, if you're throwing an O2 sensor code on a turbo civic that didn't have one I'd be more than a little scared. It's extremely common to disable the O2 sensor when tuning the car, but if it's not there and it's throwing a code I have to wonder what kind of tune you have (if it was even tuned)

 

Thanks I appreciate the legit answers unlike this smart guy plan on getting the right sensor and taking it to get it tuned immediately, can't trust other people at all

 

Btw, if you're going to get it tuned you might want to just invest in a good wideband O2 sensor and forget all about the factory narrowband.

 

Wouldn't I want to keep it in the pipe to clear the cel and for the tune? I'm also adding in an AEM wideband which I just ordered. FYI was planning to tune with hondata, can I just ditch the narrowband entirely?

On a side note any ideas for the other code I'm getting?

 

You can just plug the whole with a threaded plug and disable the O2 sensor with whatever tuning program you're using.

Either there's something wrong with the wiring going to the TPS sensor or the sensor itself is bad.

 

Your welcome
