I had my codes ran today and it came up P1153 but I dont know what that is. Autozone people are stupid in my town. I know someone put the codes up and what they mean but I cant find it. Any help is appretiated. BTW fixed my MAF sencer and camshaft position sencer-they dont send codes anymore(left a hose disconnected and I finnally found it)

 

P1153 - HO2S Insufficient Switching Bank 2 Sensor 1

Bank 2 Sensor 1 is the passenger side O2 sensor on the tail pipe right in front of the 'Y' before the cat. I bet you are getting some pretty bad fuel mileage as well... I'd get it replaced and I recommend that you don't cheap out on them. Get GENUINE AC Delco sensors either from your dealer or from an AC Delco store if you are lucky enough to have one close by like me. The sensor will cost you ~$78 from an AC Delco store. Which isn't all that much more than the crap that is Bosch and the rest of them (speaking of O2 sensors for GM vehicle applications only).

 

I had it eraised yesterday and it hasnt come back on yet... I got 200 miles on 3/4 tank(dont remember if thats good or not), put 400+ miles on it in 3 days right after I got it back, thats going from my house to 1 hr south of Chicago, and back. got 18.5 mpg on that trip.

 

got 13.3 mpg ouch!!! had codes ran again and they are0153 and p1153, advance said 0153 is o2 sensor CKT slow response and 1153 Manufacturer Control Fuel Air Metering.

 

It usually takes afew key-on cycles until all of the emissions checks are completed.

On to the codes:
P0153 HO2S Slow Response Bank 2 Sensor 1
P1153 HO2S Insufficient Switching Bank 2 Sensor 1

Looks like your passenger side O2 sensor is shot. I wouldn't go with anything but AC Delco O2 sensors. You can grab them online from RockAuto.com or if you are lucky enough to have an AC Delco retailer near you, from them. The price usually runs right around $70/each and you are looking for an AFS-105. I have never had anything but bad luck with any of the aftermarket O2 sensors in GM vehicles and have actually seen a brand new Bosch sensor trace along side a brand new AC Delco trace and the activity of the AC Delco sensor blew the Bosch away.

 

Thanks for he help swartlkk, have to wait a few weeks though, I have no $$. Just spent $200 on a new clutch set.
