Front O2 Sensor

[cracka400]

ok guys im still trying to work the bugs out in my car. I checked the codes on my computer and I am throwing a front o2 sensor code and cts code. My question is , someone put a 95 ka24de in my 98 240 and im wondering if by chance the computer is throwin the code because someone might have not changed the sensor when switching motor and computer? If that is the case why im throwing a code for it then ill change it over if there is any difference between 98 and 95 o2 sensors. Thanks a ton guys.

There is a diff. in 95 o2's and 98's. The 98's are OBD2 whereas the 95 is OBD1. Sometime in 95 they were swapped to OBD2 but its rare you find one. (at least i havn't seen one) You said they swapped the computer too right? I'd repace it with an OBD1 and go form there. Thats just my opinion.

ok well the is the 95 a 1 wire o2 or 3 cuz in my car i have a 3 wire o2 in it.

The 95 OBD1 front sensor is a 1 wire sensor.
