What does the PO441 code on a 1997 Dodge Ram 1500 mean?


  • Hi, i can help.
  • That code means "Evaporative Emission Control System Incorrect Purge Flow."
  • This most of the time is nothing more than a gas cap that is not on tight of the seal is worn out. Make sure it is on tight. If it looks tight then the seal is bad and the cap should be replaced.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

What does code ccd mean on overhead display 1997 dodge ram 2500 diesel 4x4 automatic?


It means "Crystal Clear Display" but in basic term its called a ccd bus, basically the OH console module is not communicating with body control module so you want to check power and ground pins or you just might have a bad module, sorry.
A self-diagnostic test is used to determine that the
compass mini-trip computer module is operating
properly electrically.

CCD communications test.
Following completion of these tests, the compass
mini-trip computer will display one of three
messages: “PASS,” “FAIL,” or “CCd.”

if the “CCd” message is displayed, the use of a
DRBt scan tool and the proper Diagnostic Procedures
manual are required for further diagnosis.

PO700 PO740, check engine light on. Run a test on


PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.

Emissions failure due to an evap code


Your emission sensors seem to be just a 'spec' out of normal (I would not call them defective!), but it could also be tainted fuel. Just to pass test I would buy the gas treatment at your local auto parts specifically for emission testing. Ask them at the counter. It will get you passed.

Transmission light cod P0740


PO740 is a TCC/lockup code.TCC stands for Torque Convertor Clutch.In between the engine and transmission is a torque convertor.Inside the torque convertor is a clutch.This clutch engages to eliminate slippage inside the torque convertor.When a malfunction occurs in the system,which is activated by solenoids,and a computer,a TCC code will set.There is a diagnostic route specifically for that code,to determine if the malfunction is electrical,mechanical,or hydraulic.
