Hey done a little research and just trying to clearify this. Just bought 1999Es300 and couple hours later CEL and Trac Off comes one the same time, ya I know he could of cleared right before but its great car so just want to fix this quick. Ran codes and P1155 A/f Heater Circut Mal Bank 2 Sensor 1 and P1153 A/F Sensor Response ran and cleared the codes four times just to see how many different codes came up and always P1155 and three of the times got P1153 First time I ran said system Too Lean second was P1153 third was P0125 coolant temp sensor. Just trying to see why I get the same all the time with P1155 and different second code. and got P1153 three times. So What do youall think just replace A/F sensor Bank 2 and since coolent temp sensor pretty cheap change it as well. Just seeing what Yall think. Thanks
