98 Ram 1500 4x4 throwing out P1762 and P1764. I replaced both along with the filter and gasket. Cleared code and it came right back. Reset PCM, same thing. I did replace the O2 sensors about a month ago. Any ideas? I heard the downstream O2 sensor rides on the same circuit as the gov. pressure sol/sensor but I am not sure if that's an issue as I no longer have a O2 code.

Thanks.

 

Make sure you are getting 12 volts to the trans at the 8 pin connector...... If that's good, make sure it is plugged in good.......

Edit: Ok, I think the governor pressure sensor/solenoid get power from the PCM, and it is less than 12 volts.....

Yep, pin 1 on the connector should be 12 volts, pin 2 should be 5 volts. Make sure you have both.

 

Thanks!
