you can read through the suggested answers and you can read through this discussion to get insight into the problem. Dodge Codes P0315 and P0339

You tell us why they could not clear data

You clear all data,not just one code

The code came back because that system
was not repaired yet & now the shop wants to
get away from your car & work on easier money
making jobs

If you google your PO315 --- the shops really don't
have to go to their data base, as there is info on the problem
on the internet

They either never found the real issue or put one in the car

I think they ran out of knowledge

You appear to still have CPS issues

They could not clear the code because the computer
can not recognize the crank sensor

You & I can see some of the possibles on the computer,
why can't a shop

Scan tool data would show all sorts of issues

They never road tested or looked at data-- to confirm any
work they did

Read the info on that code PO315 for a chevy


You do not give back a vehicle until you drive it 20 miles
or more & all but the Evap Monitors runs & you have no
OBD Codes in memory & confirm your work

Need a better shop for sure

Of course it comes back. You didn't repair anything. Erasing the diagnostic data doesn't fix the problem.
It means that the Crankshaft sensor variation has not been learned. You will need a professional, bidirectional scan tool to perform that relearn.

Depending on the make model and year, the code is for a problem with the crank sensor or the computer memory.

Code 315 involves the crank sensor, and code 715 involves the speed sensor in the transmission.
Both sensors would need to be checked, and I would think the car is still covered under the factory warranty.

the code is for crankshaft position sensor

p0128 is coolant temperature sensor below range, change sensor. p0604 is pcm random access mem ( ram error. it may mean the pcm has failed, have it checked out..
