My friend has a 02 2500 Dodge auto It will not shift in to 2nd gear. He is getting a code..

P 0500 and ECU 1693 what would that be? the P one worked but do not know what the ecu one is?


Thanks for the help HP.

 

P1693 is a companion code. DTC Detected In ECM

OBD-II Trouble Code: P0500 Vehicle Speed Sensor Malfunction

Thanks for the info..

 

what happens if my trans works beautifully and the only code i have is 1693? wat is this code it just came on after a start, last time it was driven no codes, start it and now this..

 

Did you let the key trick run the whole cycle??? After it says done the first time it still has another computer to read through, it should read the p-pcu and the p- ecu I believe. I believe the 1693 is a generic code meaning the other system has a code in it, if I'm wrong some one please corect me I believe that's what I just read

 

Output shaft speed sensor has failed most likely. Check the pids for speed sensors on the truck. It will be obvious which has failed.

Why wouldn't it just say that in the codes list instead of just say its a generic and the other computer has to have one in it??? Just curious

 

99% of these failures are speed sensor related. I vote he has a speed sensor code present, the 1693 is possibly a result of another code stored in the ecm. Regardless a code isn't a proof the sensor has failed anyway. Would you like the proper sequence for diagnosing this failure?
