O2 sensor error codes P0031 P0051 and P0136

[Rbasquez]

I am new to this forum so thank in advance.

I need some help on a 2002 ... I have 3 Error Codes (p0031, p0051 and p0136) I changed all 4 O2 sensors and 15amp fuse. Sensor 1/2 seems to have a misthread because it was hard taking it out and putting it back in. The Codes are still there and the Fuse blew again ... Any ideas?

What brand of O2 sensors did you replace them with?

The sensors are all NTK. I’m thinking they may be a short somewhere since the fuse keep blowing as well.

Yep, that sounds like a possibility indeed.

Where is the fuse for the O2 sensors?
