Hey Guys and Gals,

I just got two codes on the crossfire, a P0720 and P0600. What do I need to do next?

Thanks

 

Find out what they mean.

720 - Output Speed Sensor Circuit

600 - Serial communication Link Malfunction

 

From Dodge/Chrysler DTC codes list....



P0600­ PCM Failure SPI Comms

P0720 Low Output SPEED Sens RPM, Above 15 MPH





Edit: ooops, tighed1 beat me to it....

 

Thanks guys. I knew that what they mean but now I need to know what that mean. LOL

720 - Output Speed Sensor Circuit (Where is this and what needs to be done)

600 - Serial communication Link Malfunction (Is this the PCM going bad)

 

Look in the service manual, NAG1 - ELECTRICAL DIAGNOSTICS 21 - 109

that would be section 21, page 109. Trouble shooting for P0720 error.



edit: look at page 21 -1 and it lists all the error codes for the transmission. P0600 has a BUNCH of causes to trouble shoot.

edit: and here is the link to get the service manual...

Thanks Mike,

I download the service manual and take a look. Thank you again for the help.

 

I just got these same 2 codes. If you dont mind me asking what was the end fix? PCM? Any help is greatly appreiated for this new guy.
Thanks.

 

I also have these same 2 codes. I have an 04 ltd that goes berzerk until fully warmed up. When I start it the first time for the day, after 1-5 min, the spoiler raises, speedometer quits, brake light, check engine light, etc (BAS & ESP light has been on now for several months) come on and trans is put in limp mode. Once the car has warmed up for 15 min or more, turning it off and restarting clears the problem until the next day (days are not that cold in Calif). My code reader shows P0720 & P0600 and I delete them and of course they come back the next day I start the car. I already tried replacing the (original!) battery. Anyone else resolve this issue or have any ideas? Help would be greatly appreciated

 

Has anyone resolved this issue? And to be more specific, the "brake" light, the brake warning light, and the "check engine" light all come on and the spoiler raises. This is happening more frequently now, sometimes after the car has been running for quite awhile. I have tried disconnecting and reconnecting all the wiring connectors to the PCM and the ESP. Any help at all would be appreciated.

 

Omg i'm about rdy to toss my crossfire in the river. In the last 4 months I've had issues with it. Just yesterday coming home from the gym. I'm at a stop light. Push on the gas and bam the car jerks hard. Car gets stuck in first gear and wont change at all. So i'm going 30 miles an hour with the rps hitting 4 grand mark. I pull over, turn it off same thing stays in first. check engine light comes on along with BAS and ABS. Get the codes p0500 and p0720. Ontop of that thats not the only issue I had. 2 months ago my car would shut off on me while driving. I'd get out and push it to the side. Try and start and it has juice but not enough to turn over. I get it jumped and turns right on, I drive and it shuts off again same thing won turn over. Well check engine light comes on. Come to find out my Crankshaft positioning sensor was bad and needed to be fixed which was only 50 bucks. I swear this car is becoming a total money sink.

 

Check benzworld - post 10 sounds like MB tech with experience and good advice. It's a ml320 but some of it may apply or at least be food for thought.
