you can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassemb ly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete
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
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.
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.
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..
CODE PO335 CRANKSHAFT POSITION SENSOR CIRCUIT. CODE PO315 - NO CRANKSHAFT POSITION SENSOR LEARNED. POSSIBLE CAUSES, CRANKSHAFT TONE WHEEL FLEX PLATE IS DAMAGED, TONE WHEEL PULSE RING MAY BE DAMAGED, ERRATIC CKP SENSOR SIGNALS WIRING CONNECTOR PROBLEM, CKP SENSOR HAS FAILED, PCM HAS FAILED.
