I am getting this code on my 2001 Nissan Pathfinder LE.P1140 HO2S Transition Time Ratio Bank 1 Sensor 2
Can someone tell me what this means and what I need to get fixed?
Seems to be an oxygen sensor.


Thanks.

P1140 is intake timing circuit, Check oil level. If oil level is good bank 1 (pass side ) remove and inspect intake timing sensor, most likely your either low on oil or you need the sensor. GL..

Seems like the oil is fine. Must be the sensor.

Thanks!
