According to the blinky blinky ABS codes list on the Rovers North site:
Fault Code/Location: 2-13 Rear Left
Cause: Sensor Air Gap too Large/Sensor has been pushed outwards by exciter ring
Remedy: Run out on sensor rings due to rough roads/potholes, installation Check bearing freeplay, or failure fit new sensor bush, refit sensor
So I pulled the ABS sensor out this evening after removing the left rear wheel. The center bolt holding the inner shroud is a bit of a pain to access, but I eventually got to it with a 1/4" ratchet and a short extension.
Once removed, the tip of the sensor had a bit of brown dirt on it which wiped off with a dry rag. It looked like the "dirt" was rusted steel filings, probably worn from the exciter ring (?). I assume the ABS sensor must be magnetized if it's picking up bits of steel particles.
The shaft of the sensor seemed to have a bit of a varnish coating on some spots, so I used acetone and 000 steel wool to get it nice and shiny.
Lastly, I applied silicone dielectric grease and pushed it back into the hole. Tapped on it with a piece of wood and it looked like it was in as far as it was willing to go. Note that I did not disconnect the sensor at the connector point since there was plenty of room to work on it in-situ.
Got into the truck, shorted out pins 5 & 15 on the OBD II connector, switched ignition to position 2 and waited...
The flashing of code 2-13 began again
So I pulled the OBD jumper and tried again, but the code kept coming back.
Put the shroud and wheel back on and took it for a short drive down the street and back, but the light did not extinguish. Tried another reset with the paperclip jumper, but the code will not go away :banghead:
So, am I possibly doing something wrong, or is there a problem with the sensor itself ? I should add that the ABS light has been on for about 7 weeks, and I read that there is a memory buffer for the ABS blink codes. Is it possible that there are dozens of codes sitting in the buffer waiting to be cleared before the ABS light will stay off, or am I being an optimist ?
Any ideas on what to do next ??
Thanks !
