This is one that has been giving me a hard time for a while, so I'll start from the beginning...

I was at a friends house and parked in his driveway. Only I turned the key off before putting it in park. I turned the key to the on position, shifted it in park, and turned the key off. When I went to leave his house later, the ABS light came on...

I had the ABS light checked and there were 4 codes for the right rear wheel sensor. I replaced the right rear sensor two days ago, and the light didn't go off. So I took it back to where I got it scanned and the guy cleared the code for me. But when I started the car again, the ABS light was on, and he scanned it again. This time it was one code: right rear speed sensor open/short circuit.

After this, I came home and ohm tested the old ABS sensor and the new ABS sensor. The ohms were exactly the same, leading me to believe that the old sensor wasn't bad. So I am here asking for help to see if anybody has had the same problem or can suggest the next step for me to take. All responses are very much appreciated, and I thank you in advance.

 

Broken wiring before the connector for the speed sensor. The abs wiring harness is a favorite chew toy of mice.

 

This kind of question belongs in the General Tech section, so I'll move it.
