Hello,

Thank you for the donation it is very much appreciated.

Here are the defs I have for P1152

P1152 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2

P1152 O2 Sensor Heater Circuit Low Voltage (Bank 2 Sensor 1)

P1152 Lack Of HO2S-21 Switch Indicates Rich

Ok, First thing to check is the Fuses for the Heated O2 Sensors.

Next would be to either put the vehicle on a Scanner capable of showing the wave forms of the sensor or just replacing the sensor.

Also are there any other drivability problems?
