P1089 – O2 Sensor Circuit Slow Response in Lean Control Range or Issue with 4 WD

--
- Faulty VVEL Control Shaft Position Sensor Bank 1
- VVEL Control Shaft Position Sensor Bank 1 harness is open or shorted
- VVEL Control Shaft Position Sensor Bank 1 circuit poor electrical connection
- Faulty VVEL control module

.. Just disconnect the o2 sensor and read dtc´s.. If no dtc is extra you will know it is o2 sensor.. And so the same with the other.
