Engine and loss of power light came on.

Your vehicle is equipped with a computer. The computer monitors nearly everything. If there is a problem, it records the problem and stores it. Using an OBD2 scanner, a person retrieves trouble codes from the computer.

Here is a guide to show you how

There are many different codes. Each one identifies a different problem. Once the code is obtained, a shop or anyone can look up the code and identify where the problem is coming from.

I am not sure where you are located, but most nationally recognized parts stores will scan it for free and tell you what they find.

If you get the code, let me know and I can tell you what it means.

Just to add to this one if the reduced power light is coming on then your having a failure in your electronic throttle system. Get the computer scanned for codes and post the exact code numbers not the code descriptions.

It all depends on what the actually problem is on how much it will cost to fix. If the computer doesnt detect the problem next key cycle the system resets itself. It will only go into reduced power mode when the computer detects a problem in the throttle system. Usually the problem doesnt fix itself get the codes read and post them.

A plugged cat doesnt turn on the reduced power light that turns on because of a issue with the throttle by wire system. They said the power light came on meaning the reduced power light. Plugged cats will not turn that light on but thanks for the info on the cats.

Your welcome thats what were here for.

Was a professional scan tool used or diyer scan tool to read the codes?Also what are the exact code numbers not code descriptions found?The two codes your talking about shouldn't case those symptoms. Have you had a exhaust back pressure test done yet?

Have you checked the EPs fuse in the under hood fuse box?Its the square fuse with a clear top you can look thru the top of the fuse to see if its bad. Also have the car scanned for codes and let me know what the exact code numbers are not code descriptios are.

So the reduced performance light comes on?If so there is a failure in the throttle by wire system. You need to get me the exact code numbers not code descriptions?

Sure, you could have. You need to have the codes read to determine why the check engine light is on and that should get you pointed in the right direction.

The first thing you need to do is take it to a auto parts store and have them scan it for codes. Let me know what the exact codes are.
