Speed Sensor

[allcaps55]

Has anyone gotten the codes C0205 and C1236 and simply cleaned the speed sensor to fix them? I replaced that same sensor about a year ago, albeit with a cheaper than OEM part, and am just wondering if cleaning might actually help or if I should just go ahead and purchase a new sensor.

No but I have had some bad contacts with aftermarket parts and so using an eraser or contact cleaner has helped a few times

Have you checked your wheel bearings? I wonder if there is too much play allowing the bearing to touch the sensor.

I have not checked for play in them since my last tire rotation about 3000 miles ago although I haven’t noticed any noise coming from them. I’ll be sure to check again once I get a chance to get the truck back on the lift

Well I cleaned out the speed sensor mounting hole, replaced the sensor, and cleared the codes only to continue to get ABS engagement at low speeds and the codes returning after 10 minutes. My next step is ABS wire testing.

Does anyone know where to find the continuity ranges for the speed sensor cable? I’ve been reading that a generic number would be between 800-2000 but not sure if this truck is different.
