Finally registered

Hi everyone, I finally registered & I wanted to share my success. I have been looking at the posts for 5-6 years when those little lights pop up on my dash (& eventually go outl).

Last week the skid light (Traction light) & CEL (Check Engine light) came on .
I have 83,900 miles.
The Trac light has come on before & eventually goes off.
After 5 days it continually stayed on.
I searched Google & found the most logical reasons on Tacoma World.

(sensor bank (PO 137 02)), (regulator), pre & post sensors...etc).
I picked up a cabin AC filter & installed it..... routine maintenance (yesterday Mon. 7-11).
I did not know that O'Reiley would check the codes.
I was going to have O'Reiley check the codes today (7-12) but the lights went out after I installed the filter.
One of the treads on CEL & Trac Light stated that he replaced the heater relay & it solved his problem.
My only explanation is that my (really) dirty filter was putting a strain on the relay or unit because I used the defrost a lot lately to burn the dew on the window in the morning.

Hope this adds a possible answer if any of you have this problem....
Regards......
