Stuck at the top of this forum.... DTC Codes

 

thanks blonde moment there.. lol



P1148= Closed Loop, Bank 1

p1168= Closed Loop, Bank 2

anybody know what might be causing this?

thank you ..

 

I think maybe your Z is taking longer than normal to go into closed loop or one of the sensors is preventing it to go into CL so it threw the codes. Take it to a dealer and have them figure it out. This will affect your STFT which would affect your A/F.

 

thanks bro!

anymore suggestions?

 

For this kind of problem, its better to have the pro with proper equipment figuring out. Factory scan tool has way more data than any other independent shop scan tool. It worths the $ to have dealership find out the problem in one shot, rather than spending money to keep replacing parts.

I checked the TSB for you and I didnt see any. And it has a lot of possibility causing your car to have a hard time getting into close loop. Problem with warming up, defective sensors, thermostat stuck open, e.t.c. And sometimes a simple ECU update will correct the problem which you can never able to figure it out by yourself. One suggestion for you is search the forum and google to see if anyone had the same problem, if not, bring it to the dealer.
