does anybody know what this part is called in my 2001 dodge neon ? I think it is a sensor but ain't sure. Thanks

 

code P0601, P0132, P0134 are some of the codes I am getting.

 

Welcome to the 2nd Gen Neon forum.
I see you don't have any replies yet, so I'll see if I can get things started on your trouble shoot.
The P0132 & 134 codes are for the upstream O2 sensor.
The P0601 code is for a ECM memory checksum error. Did you happen to disconnect the ECM with the battery still connected?
