Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Dear customer, thank you for choosing Justanswer. My name is***** would like to help you.
I am now dealing with your question, I will be back in this chat in a few minutes.
These two errors are difficult to differentiate.
Does the car have a loss of power?
If so, then the flow controller on the high pressure fuel pump should be checked and the wiring harness to it should be checked.
If not, the O2 sensor should be replaced first.
We have two faults here, one of which is the main fault and one of the secondary faults. Here you can only try.
If there is no loss of power, you should start with the O2 sensor, because it is quite often defective.
I would be very happy about a rating with 5 stars over the star bar at the top of the page, without this rating the site operator does not pay us experts.
