Isnt good; the bad news is, this is an internal failure. Sometimes you can clear the code and it won't return. But most of the time you need to replace the PCM. Something inside the logic get garbled and throws that code.

Good news...the PCM is an emissions related component. I believe it is covered under warranty for 8 years or 80,000 miles. Check with your dealer. Just like catalytic converters and such.

P0601 - Internal Control Module Memory Check Sum Error
Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes: A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions: With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

Hope this helps (remember to rating this answer and leave some testimonial comment).

this code relates to the EVAP LDP , the pump sensor needs investigating ,this is used to prevent fuel fumes escaping to the atmosphere

Or worse, if it has bent valves, so yes do check compression. That is an interference engine design.

Would you like us to guess at something for you, without having the vehicle to look over? Have you checked for fluid leaks? Considered you have to flush the fluid every 3 years ,or the steering rack fails?

Hi there, check to see if your power steer reservoir is full, if so then your power steer pump has failed, they usually make a noise when low on fluid, that would be the first place I would check, then check for and fluid leak from the reservoir , hope this helps

Under the hood prob under your battery

could be a line or steering rack

remove old nstall new nothing to it

what have you tried

Near the end of the acclorator cable.

It is almost a sure thing that you have put a lower amperage fuse in a higher amperage socket. To verify, look at the fuse box cover, it usually has a legend of what fuse goes where, and what the amperage is. Make sure that you put 15A fuses in 15A slots etc. Also make sure that the fuses are not burned out, look for the little piece of metal that make the connection, and make sure its intact.

The PCM is VIN specific so unless you have a Chrysler Star Scan tool and the VIN codes, there is no way for you to do this. Take it to a dealer.

The PCM output drivers for the coils have failed. No uncommon. New PCM is required.

Have the computer scanned for trouble codes. If a fault code is set, post them here, or google the code to get descriptions.You should have the fuel pressure checked to see if it is at proper pressure. A weak or tired, old pump just may not be getting the pressure needed. There would be a specific pressure required for your car, but multiport injection is usually about 40-50 psi. If a shop tests pressure for you, they can find your required pressure, and then check for it..

There are cheap OBDII testers at Walmart 30 Bucks you can pull the codes yourself to see what it says. Also AutoZone will rent these for a deposit when you bring it back the give you your deposit back.If the engine turns over and is not starting I would check the Cam sensor first then the crank sensor. Each spark plug has its own Coil on top of it. These do not fail often rendering the auto in a no start condition. Another thing to check is the Fuel Pressure regulator this holds the Fuel rail pressure at an optimum firing pressure to get best spray from the injector if it is low or just simply not building up pressure this could be some of the problem, (BUT) this still in most cases allows the engine to run it will do so just poorly. Also if you can not remember when you changed the fuel filter last try this as well a dirty fuel filter can stop a engine from running. And last but not least just because you hear the fuel pump coming on does not mean it is operating how it should and producing the correct pressure threw the fuel system. The pressure should be tested to see where it is at.
