Engine stuck on 3000 and check engine light

  • 240,000 MILES
Hi guys,
I have a problem that before 2 days I was fixing my radiator so temporarily I removed the wire of crank shaft positioning sensor which is installed in my gearbox. When I installed that wire again the check engine light appears and I didn't able to take my engine race above 3000 rpm.
engine stuck on 3000 rpm and vibrate

example - just like we put full gas and rpm stuck on 6500 rpm.
Do you

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.

If you already suspect the Crank sensor as being the source of the problem, then inspect it for damage.
