Error Code Engine light came on after car was serviced. Error code po605?

I can't remember what a PO605 code is off-hand, but I do know that it is a PCM code, and not a BCM code. There are 2 different computers.

po700 automatic transmission control system malfunction. code po605 engine control module ROM error. code p1192 inlet air temperature circuit low.

Its whats called an error code in my opinion.... Here's what to do...locate your ECM ,pull the plug spray with QD cleaner ....and reinsert..... 99 to 1 your light will go away....oh u may have disconnect the battery after wards to actually turn it off but that should work...hope that helps

Dear Oti,

Replace The TCM. This Code Comes Up When Transmission Gets Stuck In A Gear.
Hope This Helps.

Its the TCM- Replace the Transmission Control Module. WITH THE DRBIII PERFORM QUICK LEARN AND REPROGRAM PINION FACTOR.
The transmission Control Module (TCM) is located behind the passenger fender and is fastened to the frame rail forward of the suspension. Here is a picture of it...

P0700 indicates the transmission control module has a code in it. That code is P0605 which indicates a TCM internal memory error. While the TCM would probably be the leading suspect you can't rule out other possibilities like corroded connections, etc.

Trouble Code: P0605

Internal TCM Error
Possible Causes:


PCM needs to be replaced, and then reprogrammed

po700 is the code in the pcm,telling you there is a code in the tcm( trans control module) po605 is a internal tcm error replace and program the trans control module

p0700 is a generic trans. code, so the problem if it is in the trans. would require further trans diag. so i would scan trans specific codes first. but in most cases when a chrysler tells you it is an internal controller fault you can believe it. just make sure which controller it is telling you has a fault!

Do not walk, RUN from that repair shop. A PO605 reading is "PCM read only memory test error". There is no way a problem in your DVD player would result in a "check engine" light. Take the van by Autozone, Advance Auto, Pep Boys, O'Reily's or other retail store and have them run the fault codes on the OBD-2 computer to find out why the light is coming on. If you are having trouble with the DVD player, go by a stereo/video shop.
