I have a 1999 camaro V6 3.8The check engine Code is P1153.what can i do to fix it ?

Answer 1

P1153 Insufficient switching 02 sensor bank 2 sensor 1

When a 02  sensor malfunction this is from either the heater ignition feed or the ground circuit to the 02 sensor to a poor connection to the 02 sensor.and even the 02 sensor itself, Voltage measurement should be done first on the heater side,and the ground should also be measure,
