PSM Warning Light Comes On During Sweeping Left Turn

[drstephensugiono]

I have an 04 CTT and during a sweeping left turn the PSM warning light comes on an the fuel cuts off. It could be slow or medium speed on dry roads without slippage. I understand it coming on that when I gun it in the rain. Could this be my diff is going bad? Or is my speed sensor loose? Anyone experience this?

Have the ABS system checked for fault codes. You probably have a wheel speed sensor failing.

I suspect the speed sensor but don't know which. Also I replace the driveshaft, but still hearing slight knocking when I start driving from the right front. I was wondering if the front shaft is bad.

If you check for fault codes it might point to which sensor is at fault.
