P2119 — Throttle Actuator "A" Control Throttle Body Range/Performance

This one came in runs on 2cyls. Codes for throttle body. Decide to check why only 2 cyls before checking throttle body which I will most likely find bad throttle body. Found Injectors are shutting down for 2 and 3. Grab capture of cam/crank and find crank signal dropping out/lots of noise. Installed new sensor and signal is clean now. Found cyls 1 and 4 now shutting down. So, restart at different times and the missing cyls will change. Sometimes 2 and 3 then other times 1 and 4.

Is this a function of limp mode on these? I found no documents in alldata. I want to insure this will run on all 4 before replacing throttle valve.

Hi Shane, Did you follow the flow chart for the code? All Data has a good flow chart. No Parts cannon.

Is the ckp sensor oem? Aftermarket sensors don't work well on Mopar. But no , that's not how limp strategy works

I had one recent with aftermarket sensor that shifted crank signal off enough degrees that ecm set cam and crank codes. Crank pattern by itself looked good. Will have to check but believe one used it ngk or ntk branded. Have seen injector disable on cat protection from missfires or from decell fuel cutoff.

I had that problem with my patriot …08..to get it to work i had to reset the adaptive numerator….my autel has a special function of that in pcm section….you have to do this when a crank sensor gets changed in these!!

I believe it is a function of reduced power. I also have not read anything about killing cylinder injectors,but discovered it while chasing a p0069 &p0101 on a '14 Malibu due to a loose intake manifold after another shop replaced MAF and throttle body. Pcm would kill injectors when code would set. Not necessarily the same injectors each time. Chase the p2119 and not injectors circuits.

Solve the Code for the throttle body, and the misfires will go away. This is part of the ‘limp home’ strategy on many newer vehicles that have throttle codes. It cannot trust the throttle, so it disables power and cuts cylinders. This is normal operation. As I stated: solve the throttle code and it'll run fine.

Tim, You are absolutely correct. I have had these before. Sometimes you can clean and lube the throttle plate, relearn. Usually, you just have to replace it. Mike

Did repair for code and fixed injector problem. Too bad it is not in SI on computers reaction to the code. Or at least I did not find it. So, now we know how chrysler handles it for this model. :)

No idea on a Dodge, but Volvo from 2001 or so will certainly cut cylinders when the throttle body is frozen. Not always the same cylinders, either.
