I was just driving home from a friends house, and I got a check engine light. As soon as I got home I pulled out my sct and got DTC code P0153. Now I have read up on here that its just a slow response to the 02 sensor, this code is for the front drivers side, but my question is, is it anything serious that I should be worried about? I am going to call JDM as soon as they open tomorrow and ask them since they tune my car but I want to know if its anything I need to worry about or pay serious attention to.

Also I never got this with my bama tune before I installed the m90 so maybe its a tune issue?

 

Sounds like they didn't account properly for the headers. I'm guessing that since you have the stock manifold for sale you just added those? Did you have it retuned? Basically it's just taking the computer longer to get the proper readings it expects when it makes an adjustment to the fuel mix because it's expecting those 02 sensors to be much closer to the exhaust ports.

 

Sorry shouldve been more clear but its the intake manifold for sale. But not I have had the headers on since around January and never got it with the bama tune. I am going to call JDM in the morning. I cleared the code so I am going to drive a little in the morning and see if it comes back on. Just want to make sure its not serious that could be causing damage to the motor.

 

How long and how many miles have you been running the JDM tune? If it's very recent, then I'll concur that the tune didn't turn off the O2's.
