I have a 97 Ram 5.9. I recently had a Magnaflow catalytic converter and high flow muffler and dual pipes installed. Two days after installation the check engine light came on. It coded P0132. Two days after it came on it has gone off and not come back on. Would the new exhaust system cause this problem or could one of the sensors have been damaged during reinstallation in the new equipment. Thanks For Any Input.

 

That code is for your oxgyen sensor. The upstream (closest to the motor) on the driver side if I remember right.

Did you have true duals installed or just dual out from the muffler?

 

Duals from the muffler back. There are two sensors: one that plugs into the cat. and one between the cat. and the muffler. Are these the O2 sensors or are they upstream closer to the manifold?

 

Into the cat? [&:] I've never heard of one being there.

Yeah, there should be at least one up closer to the manifolds. There could be two (one on each side).

 

What I meant is there is a sensor that connects to the y pipe as it enters the CAT, not into the CAT body. The full code is P0132- Bank1 , Sensor 1- Sensor Circuit High Volts. Thanks for the help!
