Which is pin 1 and pin 2 on sensor
Expert:  John replied 5 years ago.

When you look into the connector opening of the sensor there one long pin and one short pin right?

 

Look at the top of the connector where the lock clip is,If you were going to push the connector on to the sensor and you have the sensor in your right hand with the lock clip up,pin one would be the closes to you.( if there is a long wider pin it number one)

Customer: replied 5 years ago.

the sensor I have, both pins are of same size. could you tell me this way. The sensor has a mounting bracket and both pins are parallel to the bracket, one pin is closer and other pin is farther, so this way which one would be pin #1 and which would be pin 2

Expert:  John replied 5 years ago.

When the sensor is mounted,the outside pin is number one like the first picture i sent you.Pin 1 would be towards the front of the car and pin2 would be towards the engine

Well, i installed the sensor, connected battery terminal, but tried to erase check engine light and it still stays on with code P0073
Expert:  John replied 5 years ago.
Does your PCM have two or four connector on it?
Customer: replied 5 years ago.
Computer has 4 connectors
Expert:  John replied 5 years ago.

Did you try switching the wire in case there wrong?

You can use a volt/ohm meter instead of a DRB3 by back probing the connectors
