I have done searchs but still confused.

I have LG Streets, Highflow cats and intermittently I get a P0153 code thrown. Intermittently in that I got it on Saturday night, reset it and drove about 20 miles did not get it. Went into a store came back out about 20 minutes later to drive home and got the code on the way home.

What do I need to do to resolve this code? Take it to a tuner and have it tuned out.. buy new sensors? Just confused - could someone that knows LT Streets tell me how to resolve this? I would rather not have a check engine light on and I do need to pass the plug test every August.

Thanks,

I'm thinking you want to know the status of the forward O2's, so no, you do not want to have the code tuned out. I'd do an inspection of the wiring, and you could simply swap front O2's, and see if the code changes to a P0133.

Thanks. I'll see if I can do that and see where it leads.

I have the exact situation. Please keep us updated on your findings and good luck!

Will do. currently, the P0153 error points to a possible issue with the O2 Sensor on the passenger side. (P0133 would be drivers..). I'm going to check all of the clamps for a possible exhaust leak and replace the passenger sensor (in my case it's the rear heated sensor). And see if that clears the error or not. I'm not getting the P0133 at all, so it's either an exhaust leak.. or the sensor just went TU (probably).

Not true sir. If you have a P0153 code, that is for sensor #1, passenger side, forward of the cat. Not the rear sensor.

I agree.. but... With the LG Streets on my 00. They move the rear up to the front and use that one. So, I would need to replace with like. In "normal" setup, it would be the front - non heated sensor. I got that info from talking with LGM. Even though it points to the front one, I need to replace it with a rear heated one due to the LTs.

Wow, you almost confused me....

Yes, if you installed the rear sensors, using the adapters, in the front locations, the replacement of bad sensor would be with a rear O2. By the way, all the O2 sensors have heater circuits.

Interesting that both are heated. Thanks for the info!

I installed my LG Street's almost a year before having a tune. Until that time I was only getting the standard P0140 & 0160 due to the modified configuration. Once I got the tune is when I started throwing the P0153. The timing of the new code makes me doubt that it is a sensor, leak or anything other than PCM gremlins. Or so I hope.
Keep us posted and I will do the same!

I posted just a minute ago about this, I'm having the same problem, replaced both my O2's and I randomly have 0153 until the car is warm. On my AFR gauge it's shoots to rich as soon as the code is thrown, I just reset the code once the car is warm and it never comes back til the next day, looks like a common issue with LG's.

I had same issue...after tubes/exhaust upgrades (see signature)...I was able to turn it off after I installed HP TUNERS.. you can set it to ignore & you'll never see this again...the increased air flow/heat of LT headers seem to ignite this PO153 code after some aggressive or stop-&-go driving..

Today, I changed out the passenger side O2 sensor and so far have not received the p0153 (or any errors) since. Need to give it a few more runs, but it "appears" to be fixed as I have started (drove) 5 times since the change (out to eat, back, to someones house, out again, home, etc... and no Check engine light or PCM errors.

Any new info on this? I'm having the same problem.

bhoch

I have not had the code thrown since changing the O2Sensor

Good to hear, it's a fairly common glitch!

My latest trials with this indicate that babying/short-shifting/lugging the car during the warm-up cycle exacerbate this problem.

If I wind the car up just a little (shifting at 2500-3000 RPMs instead of 1700-2000) then the next gear keeps the RPMs at 1700+ instead of dropping down to 1000.

Maybe my tune is a bit rich at lower RPMs to help drive-ability.

This seems to keep the code from happening.

Could be just a lazy/failing sensor.

I know this thread is two years old from last post and close to 3 from OP, but I think I may have some more relevant information to add. This is not one of those post-it-and-solve-it things, and takes some time to figure out. Hopefully others with longtubes/cams will be helped by this:

A little history:
2008
Random intermittent 1153, 1133, 153, 133 codes after installing Longtubes, Cam, 243 heads and tune. Original o2s AFAIK, 85k miles.
2009
Replaced with ebay o2 sensor, cleared up 115x codes, but not the 15x codes. As suggested on another thread - Opened up the fins on the sensor, no change in problem. 92k miles
2010
Tired of R&R o2s more often than changing oil, I bit the bullet and replaced with $100 each Bosch Sensors. Much beefier looking outside, who knows if the internals are different. 95k miles
2012 99k miles
Worked well for a year. No Codes at all. but probably only 1500 miles of driving. When driven, driven "spiritedly" after warmed up. Been off work for 18 months, so not driven very much

Last week driven to work. Ran like a champ. Couple Spirited romps to 50mph surrounded by 25-35mph cruising.

This morning, Was in a hurry, fired car up and without giving it a few seconds to idle down or waiting to turn on AC (90 deg w/95% humidity here), moved the car to shut garage door. Heard the idle change while setting the house alarm and shutting garage. Sounded "hunty" rather than the normal lope/chop. Checked codes - P0153C.

Could it have been there when I shut it down last week? Maybe. Would it be P0153HC on restart? According to the guides this only runs when coolant temp > 150, which it most certainly could not have been after 30 seconds.

The drama continues...Will post updates as I learn more.

Hate to bring up old thread but, I'm currently having the same issues as u with my LG long tubes, wanted to know if it's worth changing the rear 02 or what u did to solve the codes from popping up?
