A little while ago, I was at my girlfriend''s house. On the way home, the route required me to drive up a long hill. At the top of the hill, my CEL came on, so I pulled off the road and plugged in my SCT. The code was:

-

· P0153 02 Sensor Circuit Slow Response (Bank 2 Sensor 1)
-

I cleared the code and drove home, and it didn''t come back on.

A couple weeks later, I was at my girlfriend''s house again. The same exact thing happened. Went up the hill, CEL on, pulled off the road, read the code (P0153 again), cleared it, no issues since.

I have driven up that hill countless times before the 1st incident, between the 2 incidents, and after the 2nd incident.


Is this just random occurrences? What does the code mean?

 

Drivers side FRONT 02 sensor. Check the sensor itself, loose wire or carbon contaminated.

 

it's the tunes you are running. you have long tube headers that moved your o2 sensors back. most of the time their mail order tunes take care of this. did you have the tune made before or after you put the headers on? if it was before, brent can make a couple changes on your tune taking into account the headers and that may rectify the problem. if the tune was programed after the headers and for the headers, you may have to dyno tune it, which isn't a bad thing at all!
