- Pop your hood.
- Put the car in Neutral.
- Set ignition to ON.
- Roll your windows down.
- At this point...it should be silent.
- Now put the car into gear. I usually go with 2nd. You should hear the whine start right away.
- Now put your ear near each throttle body and confirm. I could hear each throttle body whining.
I had my service manager convinced it was the ECM...and it turns out that wasn't the problem. Here is a video of the noise well. Car is in gear.
Throttle Body Whine |
Sorry but I've never heard a silent internal combustion engine
Sure I've heard the noise, and I don't have to put my ear next to the throttle bodies. Is it indicative of anything wrong? Absolutely not.
Enjoy the hassle of the dealer trying to get them to troubleshoot something that is completely normal. On the plus side, they might break something unrelated, so you need their service for real
