GT 2.0 JTS Codes and Advice Please
Hi I had the MCSF light come on and the faults I got are as follows:
P0156 - O2 Sensor Circuit Malfunction (Bank 2 Sensor 2) - Present
P1161 - Lambda 2 heater below catalyst - Intermittent
P0159 - O2 Sensor Circuit Slow Response (Bank 2 Sensor 2) - Intermittent
P1172 - Mixture 1 strength (multiplicative) - Present
P1175 - Mixture 2 strength (multiplicative) - Present
Im guessing the mixture strengths relate to the lambda faults? is there any common issues I should beware of before I just go out and replace the lambdas.
Driving wise I guess it does lose power now and again but not all the time and also the idle is sometimes erratic, other than that it drives fine and mpg hasn't really changed that much either.
Any help much appreciated.
