F23a1 and f23a4

[20accoedex01]

I asked this topic on driveaccord.com but all I got were stupid replys from a idiot so I figured I'll ask it here since if gotten lots of help from y'all. I have a 01 accord ex with the f23a4 the oxygen sensor is bad but I don't have 300 for a new one. My lx with a f23a1 that was wrecked has a brand new sensor. Could I take that sensor and the ecu from the lx and put it in the ex and just reprogram it to my key?

They sensor may work just compare the plug ends first. Not quite sure why you think you would need the ecu, a o2 sensor wouldnt need it to swap. As long as the plug is the same that is all you need.

The sensors are not the same. They share a plug and it'll fit, but you will get a code for the o2 sensor if you try to use the cheaper F23A1 sensor. And you will fail inspection for that code. So there's no reason to try and use it in an F23A4.

The F23A4 sensor works differently from the F23A1 sensor, so the computer will not be able to understand the data it's sending. Even if you swapped the ECU to try and bypass this, you'd most likely still get a code. That is a really complicated, flawed workaround to just spending the money on a new, proper sensor lol

They sell the F23A4 upstream sensor on RockAuto for $110.79, by the way.

Good to know, i wasnt aware.

Yeah buy the sensor from RockAuto, there is a 5% discount code good til the 20th too to knock off a few more bucks.

Ok well since I'm having issues with the f23a4 I can get a jdm f23a here in Houston for 400 will the f23a4 ulev ecu run the jdm f23a? Or do I need a f23a1 ecu cause it's the lev calibration, came as the fun f23a

 

[20accoedex01]

I ment jdm not fun. And same not came

You didn't have $300 for a sensor but now you're doing an engine swap and buying a $400 engine...? Why? What's wrong with the one you have now?

Cause I'm getting 200 miles in a tank of gas and it makes no sense to spend 300 on a sensor when I can get the whole motor for 400

Oh and I keep getting the p1381. I posted that issue in a new topic
