Hi all, I have an early 2002 Ram , a trouble code PO122 popped up, throttle position sensor/switch A circuit low. I would like to know is this a serious problem? Is there an easy , inexpensive fix for this?

 

Have a read Here.

What engine in your Ram?

 

I have the 5.9 diesel, and I have a feeling sensors will start going one by one.
I am having a problem subscribing, is there something I did wrong or not do? I was subscribed some years ago and would like to subscribe again. What do I need to do?

 

I just saw that I have subscribed, no need to answer 2nd part of message.

 

Either bad tps, or bad pedal position sensor..... have a scanner that can read live data? Should be able to figure out which one.
