My car came with a P75-A03(stock). and i popped the primary o2 sensor circuit because of faulty directions on a wideband simulator and toasted the computer. also around that time i got a code for my secondary o2 heater circuit. So I replaced the secondary sensor and replaced the computer with a P75-A04 computer. With that i fixed the 2 primary o2 sensor codes but not the secondary. With the P75-A04 ECU I was throwing a fuel tank pressure sensor code and AllData said that the code was on 98+ integras, and i have a 97 so the computer was looking for the sensor and it isnt there.
So then i bought another P75-A03. it got rid of the codes for the fuel tank pressure sensor but it brought back the seconday o2 sensor heater circuit code. i redid the flow chart and it says the "subsitute with a known good ecu".

First P75-A03 Computer it throws these codes.
P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P75-A04
P0453 Fuel Tank Pressure (FTP) Sensor Circuit High Voltage
P0451 Fuel Tank Pressure (FTP) Sensor Range/Performance Problem
Second P75-A03
P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

I have no idea what is going on. Any help will be much appreciated.

didnt feel like reading much but even if you have swapped out the o2 sensor do it again i have had a few cars come into the shop here with same issue and we replaced o2 sensor it was still there so we bought another o2 and it was gone never fully trust thsat an aftermarket part is definetly going to be good right out of the box
