Question about Cars & Trucks
The speed sensor have relation with the transmition if is automatic uses a different computer than the manual transmition, the configuration is totally different. you must change the computer and check also the cluster because is networked with the electrical system of the computer. some times you have to replace that one also and the wire harness also. good luck

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .

SOURCE: 2004 Chevy Blazer O2 Sensor
there are two 02 sensors actually on the engine. bank one is cylinders 1 3 5 bank 2 is 2 4 6. it controls the fuel to air ratio, if the O2 sensor is not working, the engine goes into limp mode, which means it is just putting as much fuel as possible into the cylinder, which will effect your gas mileage.
The O2 sensor may be fine, the pigtails off the 02 sensor go bad, the connection. I had in my car, i change the 02 sensor twice, then I found someone said the pigtails may be bad, so I cut the cars wiring harness pigtail, and the one coming off the 02 sensor, and directly wired it with the original truck 02 sensor, and it worked. all 02 sensors look similar, they screw in the side of the engine, and just have 4 wires coming off of it.
Try your origional one, and just bypassing the original wire connector, what I did was cut it off, skinned the wires, put some heat shrink rap on it, combined the wires together soldered them together, and heated the wire shrink rap, so that way it is water proof. car works perfect now.
