[Pwnin O'Brien]

no such thing as a sensor 3.

Here are the following O2 sensor locations:

Bank 1 Sensor 1: Passenger side, before catalytic converterBank 2 Sensor 1: Driver side, before catalytic converterBank 1 Sensor 2: Passenger side, after catalytic converterBank 2 Sensor 2: Driver side, after catalytic converter

Bank 1: Passenger side of vehicleBank 2: Driver side of vehicleSensor 1: Before catalytic converterSensor 2: After catalytic converter

P1145 is not an O2 sensor problem.

It's Left( Bank 2, Driver's side) intake valve timing position sensor.

Dig up Nistech's article on this one (also discusses P1135). He tells how todetermine if it's the sensor or something else.
