No improvement after replacing throttle positioning sensor

Hello I'm Danny,

What was the original problem? Did the car have a Check Engine Light code? Any information helps.Thanks for using 2CarPros.
Danny-

The original problem was that the engine reduction speed light came on car running very sluggish. Car was coded to say throttle body needed replaced. So throttle body and sensor were replaced but the car still running the same.

Hi and thanks for using 2CarPros.

Have you gotten this taken care of?

Let me know.

No, I have not.

Okay:
There is a relearn that I have tried to send you several time. Every time I try, it deletes what I sent. I am going to try one more time. Make sure to delete any trouble codes prior to doing this. If it resets while you are in the process, delete them again so the ECM can continue to learn.

Relearn without a scanner:


1. The engine speed is between 450-4,000 RPM.
2. The manifold absolute pressure (MAP) is greater than 5 kPa.
3. The mass air flow (MAF) is greater than 2 g/s.
4. The ignition 1 voltage is greater than 10 volts.
5. Start and idle the engine in Park for 3 minutes.
6. With a scan tool, monitor desired and actual RPM.
7. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
8. Ignition OFF for 60 seconds.
9. Start and idle the engine in Park for 3 minutes.

Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.


10. After the 3 minute run time the engine should be idling normal.

If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.

11. After the drive cycle, the engine should be idling normally.

If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.

12. Once the engine speed has returned to normal, clear DTCs.

Please let me know if you got this.

I got in car drove it accelerating and decelerating several times above and below seventy miles per hour. Now car is running fine that did the trick. Thank you very much.

You are very welcome. I kept seeing your post and tried a few different times to send it to you, but every time I tried, the reply was deleted for some reason.

I am glad it worked.

Take care and let us know if you have questions in the future.
