HI there,

I would start by checking the wiring harness for any damage. With 2 O2 sensor codes it's possible the engine wiring harness has rubbed through someplace giving you the codes for the O2 sensors. The crank sensor wiring could also be involved in the engine harness damage if there is any. If not, then you likely will need to replace the front O2 sensor and the crank position sensor.
