Problem code P2118
I am throwing a P2118 code. Just wanted to confirm that my throttle body as gone kaput on me. I looked the good up in a generic code book and it comes back as:
Throttle Actuator Control motor current range/performance
Does that mean the TB is jacked or is there something else associated with the Throttle I should be looking at. I have a spare TB and just wanted to be sure that's it before wasting time changing it.

try resetting it and see if it comes back on. if youve opened the butterfly without the pedal(i.e. a screwdriver)it will sometimes throw that code. i had cleaned my TB and that code up, i just reset it. havent seen it since.

if it keeps coming back its your TB. most likely the sensor cause if it was the actual butterfly or the gears in the TB it would say it is Throttle actuator stuck open or closed. unplug the sensor and see what the reading is. i think it should be like .4 and up. i forgot what it should be at check the shop manual if you have one if not i will look it up when i get home for you.

Check with a volt meter you mean? I think we have one laying around the garage.

i checked the shop manual and it says this what P2118 means (Open in ETCS power source (+BM) circuit (1 trip detection logic))
and this is the trouble area (Open in ETCS power source circuit, ETCS fuse, ECM)

Can you translate that into English now?
So it might just be a fuse is that what it's saying? Where the hell is this fuse cause I swear I checked all the fuses in the Bay. I didn't check in the inside of the car though.

the etcs fuse is in the engine bay its a 10A fuse. ok found the reading it should be at 0.3 to 100 Ω at 20°C (68°F). you check the 1st 2 pins from the coolant lines side. if that makes any sense.

Found on ClubSciontC
Could have SWORN I checked all those fuses. Guess I'll have to look again.

According to my resource, the throttle motor built into the throttle body is managed by the ECU which uses driver input values via the rheostat/potentiometer in the accel pedal to determine throttle opening angle percentage. However, the main throttle control circuit requires battery voltage as an input going into the ECU to be able to control the throttle actuator on the output circuit side of the ECU. The 12V input to the ECU has a 10A ETCS fuse in line. This fuse is located in the fuse box on left side of engine bay behind the left headlamp housing. I'd check out that ETCS fuse first. It may have high resistence or it may have just blown. I'd just replace it completely with the available spare 10A fuse.
Your engine right now is probably running in a Fail-Safe mode under conditions of a malfunctioned throttle control system. I wouldn't recommend driving while the engine is running under this mode. Replace fuse as neccessary, clear the code, and see if that code comes back. If it does, then your ECU or related circuits may need further diagnosis. But, it's pretty simple checking that fuse first to save you money on additional diagnostic fees.

So, if fuse is still good, then TB bad. Will check tomorrow. Hopefully there will be enough of a break in this freaking TN Monsoon we got going on right now.

Took another look see and found the ETCS fuse. Turns out it was blown afterall. I had to actually look at the one side as one side looked good, but the other side was broken. Fuses are so tiny so my first time looking at it, I over looked it.

Fail. Use a DMM next time instead of just looking at the fuse.
