Check eng light popped on got 2 codes P0138 and P0704, ones a torque converter clutch voltage malfunction and the other is a O2 sensor after the cat high voltage prob. How would I go about fixing this????? Any help would be greatly appricated.......Come on all you Dodge boys I know someone knows this.........It's a 99 Ram 2500 4x4 5.9L..............HELP ME.....

 

Nobody knows huh??????

 

You waited 16 minutes and then was surprised cause you had no answers?....LOL.

I would check your battery connections, and the chasis ground. If both codes are voltage related, bad ground, or bad elecrical part somewhere.

Good luck.

 

check the wiring for both, they are most likely coming out of the same part of the wiring harness and it's aweful fishy that you have both codes at the same time.

 

Thanks for the help.....It ended up being the O2 sensor that was causing it to give the P0740 code. I changed out the O2 sensor, 60 bucks at NAPA and some Electrical connector cleaner from work and fixed it right up. I cleared out the codes and ran it all day and no probs as of yet.
