98 Max with a CEL threw codes 1302 and 0413 (found this by turning ecu screw and counting flashes). Now i know that the 1302 is an EGR problem, but I cant find anywhere that lists 04 13. So i went back, tried again, and made sure i counted right, sure enough, its still 0413. Anyone have any idea what that is?

 

0413 - Upstream O2 sensor circuit slow responce fault(left bank)

 

I have the same code, how do you fix this? Where is that sensor located and where can I get it. Anyone have the part #?! Thanks.

 

I got the same code today but I searched elsewhere and found the problem to be "Front Heated Oxygen Sensor - Bank 2."
Which is in disagreeance with kevlo's response. Anyone have a concrete answer and what this is? Also where can we can all find it?

So far only us 98's are getting the 0413 ??

 

Either way, it means to replace teh O2 sensor.

 

Straight out of my Haynes book, 0413 is "Upstream oxygen sensor circuit slow response fault (left bank)"

Which o2 sensor is this (front?) and is it easy to install? Where to find it? Thanks
