This answer was rated:

The 05 venture van just coded PO 135 02 sensor heater.
How hard is this sensor to change out and where is it located.
Or could I be looking for other problems.
The van has 162k and I have just replaced the power control module then the throttle position sensor (thurned out to be broken wire just like you said.
I checked the code at Orillles and cleared it and it has not returned yet.
not too bad to replace the sensor.usually when you have a heater O2 code it is the heater inside the O2 that is bad
