#136012, "Help with CPS upgrade"


          

hi all,

Recently I had problems with Idle, so I checked the basic and found that the CPS is broken, I order one, and included the pigtail. So went ahead to make the cuts and splice, etc. Installed the new CPS, but after a few minutes the RPM start going all over the place, and finally the cars shuts down. I can't start it up again until a few minutes pass by.

When I exchanged the pigtail I put the cables in the same order, taking the connector's "hook" as a reference point.

How can I know if I did the right way but something else is wrong.

Thanks in advance.

I am confused by your wording. Are you looking for an upgrade?

What does his mean: " How can I know if I did the right way but something else is wrong."

I did the upgrade (exchange).

And I meant that, how can I be sure if I put the cables in the correct order, or maybe since it is a new CPS, something else is wrong with my car.

Hope this clears things up.

Hi, rechecked the connections and I hear a faint sound when I reconnected the sensor. Still the car won't start.

Any help?
