After installing a 200 cell Milltek exhaust I was initially getting the common fault codes P0420 (Catalyst Efficience Below Threshold Bank1) and P0430 (Catalyst Efficience Below Threshold Bank2).

After installing O2 sensor bungs/sensors I am now getting codes P0132 and P0152 and the two previous codes are not coming back.

BTW I have not reset the ECU after installing the O2 sensor bungs/sensors and I'm leaning towards thinking that this would possibly set things straight. Thoughts?

What on earth are these two new codes and is there a remedy?

Thanks

Nobody had issues with these codes ?

 

If you PM me an email address I can send over the manual for the DME codes. It is 7.6mb.

 

P0132 = O2 Sensor Circuit High Voltage
P0152 = Same

 

Did you swap the O2 sensors? I could see you getting this code if you swapped the pre/post cat wires.

The 5 wire sensor goes before the cat and the four wire after the cat. One is gray and one is black. Ill check which is which when I can.

There could also be an exhaust leak. What level did you torque the cat to turbo bolts to?

 

Oops... didn't read the second paragraph. I guess i'd check the plugs... High voltage sounds pretty weird. Good luck!
