Trouble code p500
I have a 2005 ram 3500 w/5.9 diesel motor. The speedo is inop and the ABS and brake light are on. This was an intermittent problem but has now become permanent. I have a trouble code p500 speed sensor A, just wondering which sensor this is refering to?

Is the P0500 the only code? You need to have the ABS module as well as the ECM scanned if you haven't already.

yes, P0500 is the only code. changed both sensors (transmission and rear end) cleared code and it comes right back. What will scanning the ABS module and ECM do?

There might be additional codes stored. With a P0500 the wiring, ABS module or ECM is going to be at fault, not the sensors. One of the modules is seeing a speed signal but the other is not.

1997 trouble code P0500 AND P0138
My 1997 1500 w/manual tranny is hard to start, won't hold idle and stalls. Check engine light comes on. I pulled up trouble codes with a OBDII scanner, which shows P0500 and P0138. Any help would be greatly appreciated. Thanks.

The 2 codes have nothing to do with each other.
P0500 - Speed sensor - Likely a wiring issue, but sensors have been known to fail
P0138 - O2 sensor at the rear of the catalytic convertor is likely bad. This would explain some of the running issue you explained. Don't buy the cheapest sensor out there. This is one time the OEM part is a good idea. :)
