I have noticed that now my TCS light comes on intermittently, along with my check engine light.(Engine light stays on, but when I reset it, it will stay off for a while then when it comes back on, the TCS light also comes on) Code p1519. I know this pertains to Idle Air Control Valve, but they seem to come on at same time.Is the circuitry related, or in close proximity with wiring?
Thanks

you should look into whatever code it is throwing and try and fix it. resetting a CEL will only be temporarily.

The only code I get is PO1519, which is idle air control solenoid. What does that have to do with the TCS?
thanks

im triying to think of what the TCS is, i know what the TCU is.

TCS is the traction control system.

OK, thanks guys and gals.I will pull the throttle body, the AICV, the TICv, and clean all associated components.This will probably fix my problems with idle speed.Now, is there anyone who can tell me how to determine which wheel snsor is bad, causing my TCS light to come on?I have an O'scope, and know how to use it.What should a normal signal look like? I could just check them all and compare, looking for a deviation, but if I have more than 2 bad ones, I still would not know for sure.It is expensive and troublesome to swap them for no reason.Thanks for all the help in the past.You guys and gals are great!
