2004 Dodge Srt check engine

[VIPR PWR]

What was happening with the truck to make you think something wasn’t right ?

Either your Cam or Crank Sensor is weak/failing or the wiring to it needs some repair.
A PCM "update" from what it is now to what???
I wouldn't believe that diagnosis for more than a second or two.
Yes, see what Torrie has to say. However if it tripped a check engine light, that has to be resolved. There is no miracle tune that will fix the current issue.

Good luck.

Either or those problems need to be resolved before Im guessing a factory re flash can be done ….

This is one of those examples of where dealerships won't (or can't ) work on something past a certain age. In this case the dealer can pull codes but don't have the ability to flash anything pre-CAN. For a 2004 they would've had a DRBIII in the past; for PCI bus vehicles it's a magic box lol. I'm surprised they got rid of any they had, but then again they aren't made anymore and functioning units are getting fewer and far between.

Either your Cam or Crank Sensor is weak/failing or the wiring to it needs some repair as the e.c.u. is sensing low-voltage.
A PCM "update" from what it is now to what??? What did the dealer claim?

REBOOT THE E.C.U. AS FOLLOWS:
Remove both battery cables. Make sure you remove the Negative Cable and not just the Negative Ground Strap.
Now, touch the cables together for 5 seconds or so then reattach them to the battery.
Note: Simply disconnecting the battery is NOT the same. You have to create an electrical system loop to reboot the R.A.M. in the E.C.U.
It also helps to do this anytime a
Sensor (like a T.P.S. is changed). That way, the E.C.U. sees the new sensor data immediately instead of running off the old E.C.U. memory. Otherwise, it can take SEVERAL start/stop engine cycles to see the new data provided by the new Sensor.


Good luck.

Very nice! Good to have expert input like this available to us

Good idea to get several opinions before trusting the dealership. @dancragin Dan Cragin is another excellent source
