i just had a curious question. i read that someone had same problem as me with codes 4 6 and 10 and read that all 3 of these share the same ground. i traced it and the iat and coolant temp and tps share this wire(green/white). so i spliced into the green and white wire right at the ecu plug and just jumped it to a ground to see what it done and it got rid of the code 10 (iat sensor) but didnt fix the code 4(ckp sensor) and code 6(coolant temp sensor) and i actually gained a tps code lol. any idea on this problem? btw car is 90 crx si with built b16 turbo converted to obd 1. things i have replaced: coolant sensor, ecu, dizzy, iat sensor. nuthing has fixed it and im currently trying to sell it but may consider keeping it if someone has some insight to this problem ive had since the build. just curious on if anyones had a similar problem. thanks in advance
