Intermittent ABS & T/C warning light Indication

Occasionally on our 1999 Windstar, both the ABS and "traction control off" (T/C) warning lights will come on and stay on for an entire drive. No other issues noted with the braking system.

Any suggestions as to what the cause might be?

Thank you.

Well I had a bad wheel speed sensor cause exactly those symptoms.

Just one possible cause.

Thanks.

Where is this sensor located? Is there one for each wheel?

Is it a relatively easy DIY replacement?

Appreciate your help.

(I also saw the other thread about the issues with the ABS module.)
