Hello all, so I was speeding down the freeway when my check engine light comes on and I lost power to the car. Everything was still on but for a couple seconds there was no throttle response. I checked the code and it came up as p0600. Has anyone else encountered this and if so what did you do about it? Thanks guys

Welcome to the forum. What year and trim level challenger (although by your user name it looks like you have a V6)? Are you running a custom tune or any mods done to the engine? P0600 means PCM communication was lost. Could just be a bad connection, chewed wires or the PCM itself.

I do have a 2014 sxt. I haven’t done anything to it at all. Where could I check for myself? I’d rather find something loose rather than a dealer find something loose

You could check the PCM connections. PCM is under the hood on the passenger side. Then follow the cabling to check for any critter bites in the wiring. If it is nothing obvious then clear the code and see if it happens again. If it does you may need further diagnostics from a dealership.

Only other thing I can think of that can cause a connection loss is low system voltage, possibly battery going bad or alternator.

Hi EddiesV6,

We certainly understand why this would be concerning. If you end up addressing this with your local Dodge dealer, please do not hesitate to send us a PM. We'd be more than happy to provide you with an additional layer of assistance as you work with your dealer.

A poor connection or failed ECM driver is probably the root cause of this code. For the most part, the ECM acts as a ground to control these components and modules, as opposed to supplying power to them. A loose or corroded connector is more likely than a frayed or broken wire between both devices. Poor grounds are another plausible cause. The ECM, as well as the activator module, need a good ground to operate. The wiring harness or Can Bus may also be defective and have a short to ground or an open wire.

The best advice concerning the diagnosis and repair of this particular code is to take the vehicle to a professional technician that has a Autohex or Tech II diagnostic computer. The technician can then systematically probe the wiring using the car's wiring diagram and pin values to find the problem.

I was hoping to not have to do that but I checked wires, cleared the code but the engine light came back on as soon as I floored it and hit about 70mph

So I realized I read the code wrong, it was actually p06DD and I checked my oil. It was waaaay too low because my oil cooler is cracked

Yikes. So were there any visual signs of oil leakage on the ground? It's always a good idea to check your oil/coolant levels while filling up at a gas station.

There’s visible oil leaking on the transmission and I found out it’s my oil cooler
