Check engine light and power loss in Ford Endeavour: Possible throttle valve problem

Hi, I had a similar problem with my 2011 Ford Mustang. It turned out that the accelerator pedal module was faulty. This can actually cause the check engine light to come on, the engine to run rough and stutter, especially when accelerating. Increased fuel consumption can also indicate this. Yes, this was indeed quite an issue as it took time to diagnose correctly. But once the problem was found, the car felt like new again. Definitely get your car checked by a professional. Good luck with that!

Hey, glad to hear you were able to solve this problem. I hope my Ford has something similar, that would probably be easier to fix. Can you remember how much the repair cost you? And have there been any other problems since the replacement or was that it? Many thanks for your help!

(Translated from German)

Hey, sure, I still remember. It cost me €205 to repair the accelerator pedal module and the Ford has been running like clockwork ever since. And the problem with the throttle valve? I actually had that too, but it was fixed at the same time. Since the visit to the mechanic, there have been no more problems. You're welcome! I'll keep my fingers crossed that yours runs smoothly again soon.

(Translated from German)

Wow, that's great to hear and reassures me a little. 205 sounds reasonable, and I'll be happy if my Ford runs as smoothly as yours after the repair. I've already made an appointment with the mechanic. I hope everything goes well! Thanks again for the quick and helpful reply! You have helped me a lot.

Problem actuator stuck closed

It sounds like you're suggesting that the actuator might be stuck in the closed position. This could indeed cause the symptoms described. However, it's important to have a professional mechanic diagnose the issue to be sure. If the actuator is stuck closed, it will need to be replaced or repaired.

I have pulled the throttlebody off, cleaned it and lubricated it. Are there additional steps that I can take either through this app or with my multimeter to test the actuator?

You can use your multimeter to test the throttle position sensor (TPS) which is part of the actuator. Set your multimeter to Ohms and connect it to the TPS terminals. As you manually open and close the throttle, the resistance should change smoothly. If it doesn't, the TPS might be faulty. However, this is a more advanced check and if you're not comfortable doing it, I'd recommend taking your car to a professional mechanic.
