i have a 91 rs 305 tbi automatic...my car has been throwing a code 44 for almost two months now..hooked a laptop up to the car and its showing that the o2 sensor is not getting any kind of signal...replace the computer with a buddies and it works great..buy a new computer and replace o2 sensor i still have the same problem..i replaced the connector and still fixed nothing


what wire going into the computer is the o2 sensor wire? i am going to bypass all the nonsense under the hood and run a wire straight from the o2 sensor to the computer(thats how it is anyways but there is a short/problem with that wire)


thanks in advance

 

The o2 signal wire to the ECM is pin "D7" and the o2 sensor ground wire to the ECM is pin "D6". If I remember correctly the ground wire for it connects to the back of the right cylinder head.

 

awesome..thank you very much

 

 

ok i have the computer out of the car...there is a long block of wires plugging into the computer and a shorter block...where are the d7 and d6 pins into the computer?

 

 

Here is a picture of the connectors in the ECM. Please note the two areas marked in black, those are pins "D6" & "D7" in connector "C2".
