Question about 2002 Dodge Durango

1 Answer

I'm coming up with codes Po700, Po732, Po605, Po720 when I run a diagnostic on my Dodge Grand Caravan Sport, 3.3, 6cyl. Could the TCM (Transmission Control Module)be bad or it just need re-flashing?

I dont think reflashing will help this, the first thing that comes to mind is the output speed sensor, i would replace the sensor and reset the codes and go from there, the out put speed sensor can make all this codes come up, the po720 is the out sensor, when this goes bad the trany doesnt know when to shift gear at the right time so if it shifts at the wrong time you get the other codes like the po732 2nd gear error or po605 internal trans controller, replace the sensor first and see what happens after that, good luck and hope this helps.

Dodge grand caravan 02 trouble codes po700


More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely). it will require a scan tool that communicates with the TCM to find what actually set the code as this code just tells you there is a problem somewhere with the transmission.

Im getting po700 pd and po715 and po720


The first number is a zero not an "O" P0700 is just the TCM requesting the PCM to turn on the check engine light. Because of these codes are defective transmission wiring harness, defective shift solenoids, defective transmission internal parts.

I have a 2000 Chrysler Voyager. The engine light came on and the following troubleshooting code - PO700 and PO605. Can you tell me what these mean?


The P0605 is an internal failure in the transmission controller. This code sets when the tcm fails one of its internal self tests, and i think the only repair is to replace the module. P0700 is transmission control system malfunction

Transmission problems???


The electronic shift solenoids are serviced as an assembly that is quite easy to replace. Your fault codes are all related to shift solenoid faults.

Po605 and po700


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!
