purpersr Posted October 27, 2021 Report Share Posted October 27, 2021 (edited) Hi, I have a 2011 Dodge Journey i am having problems with the speed odometer not working. the speed odometer stays at 0 then it will flicker up and down really fast then goes back to 0 and it makes the car jerk when this happens. I get a code PO501 speed senor A. I replaced the Speed input and output sensors and still have the same problem and still get code PO501. i was wondering if anyone else is having this problem or if someone could help with this problem. Thank You for your time Edited October 27, 2021 by purpersr Quote Link to comment Share on other sites More sharing options...

5rebel9 Posted October 27, 2021 Report Share Posted October 27, 2021 You replaced input and output sensors already, did you inspect the harness connections and wires for them? Code is for erratic/no signal, so you need to check the wires for good connection, and use a bit of dielectric grease in them. Quote Link to comment Share on other sites More sharing options...
2late4u Posted October 27, 2021 Report Share Posted October 27, 2021 What can cause a speedometer to stop working? The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.Jul 11, 2016 Quote Link to comment Share on other sites More sharing options...

I will clean the connections and inspect the wires. I will let you know what I find I appreciate your time and help Quote Link to comment Share on other sites More sharing options...

I checked all the connections on the transmission harness and all the connecters look good. so i did a continuity test on all the wires for the transmission harness I believe I have a broken wire in the harness for the output speed senor , I do not get any continuity from one of the wires but all the other wires in the transmission harness passed the continuity test. i ordered a new OEM Transmission Harness. i will let you know if this fixes my problem Thanks again for you help 2late4u 1 Quote Link to comment Share on other sites More sharing options...
