2002 CL500 CEL Code P0122 Throttle Position Sensor?

Hi guys! I'm new here, having a problem with my CL500.

When stepping on the gas, it takes 2-3 seconds to start going. Check Engine light on. Just got it checked at AutoZone, code P0122 Throttle Position Sensor.

Now looking online, I do not see any site even selling the sensor by itself, correct me if I'm wrong but replacing the whole Accerator Module (Gas Pedal) will correct the problem right?

Maybe I will try cleaning it first before buying a new one for $140.

Also, I just bought this CL500 used. I filled it up with oil, the wrong kind, and also overfilled it, triggering the Oil Level Warning Shut Car Off Light on the dashboard.

I got my oil changed, figuring it would fix the light since it's not overfilled anymore, but it still goes off every once in awhile.

What should I do for that? Or is it not a big deal and will correct itself eventually?

Thanks!

Yes, you need the whole pedal control assembly. They fortunately aren't too expensive and are a frequent cause of the problem your experiencing.

Easy to replace as well.

I feel so stupid asking this.....

How do you take the damn pedal off? I don't see any screws or bolts, does it just slide off and then unplug? I

Look closely and you will see it is held on with at least one bolt (or nut) near the top center of the unit if I remember correctly.

Then it will unplug.

I have a pedal for sale if you still need.

Its also simple to remove, just a small flathead screwdriver to pop up the circular cover to expose the 10mm bolt. Undo the bolt, gently lift and pull the pedal. Theres lastly one electrical connector that has to be undone. Thats it.
