Pulling these two codes, car runs, idles ok, but has very limited power. sometimes the power is jolty, like cutting in and out. If I drive very easy everything is fine once I try to accelerate a bit briskly it will try to go but slowly. The P1148 is closed loop control, bank 1 (I have no idea what that means) and P1110 I did some searching on here for and the only clues I can get are MAF or Variable Valve Timing solenoid, I'm not sure. Any help would be greatly appreciated... thanks in advance.

 

I check all my info, I got nothing on those two codes. Call the dealer, see if they will tell you what they mean.

 

P1148 - looks like it's one of your primary air/fuel sensors in your headers.

P111 - appears to be something wrong with your Intake Valve Timing Control Solenoid. Shouldn't be a big deal to replace it.

 

hmm this makes sense... I did replace one 02 sensor just the one downstream of the radiator side cat, the other 2 are old. Maybe I should replace them, and the intake valve solenoid, would that make the car run weird with reduced power? If so that makes sense too, I left it for my mechanic for tomorrow, if he cant figure it out I guess I will have to go to Nissan :/ not looking forward to that.

 

Yeah I'd imagine the IVS would make your car run weird.

As for the sensors, just get OEM ones from Nissan. I never had good luck with Bosch etc. from Amazon or eBay.

I also have the P0011 error. How difficult is it to change out an Intake valve timing control solenoid valve? Where is it located? I am not completely mechanically stupid, so if it is something that I can cahnge out myself without pulling everything apart I would rather that then paying my dealer a ton of money for it.
