Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Is this a Pathfinder?
The truck has one crank sensor.
As for the P0011 and P0021, Lets start with those two codes. Did you check the oil level?
Did you replace the cam sensors?
First off, I would like to thank you for your service!! 100% respect for you!!!
So thank you for that!
Second as for your truck. The two codes P0420 and P0430 sounds like you have two bad catt converters which could be restricting exhaust flow causing the lack of power. So that needs to be checked.
I would also check to see if the Cam Sensors are after market. If after market they can cause the P0011 and P0021 code. If not the Cam sensors, then you would have something going on with the intake timing operation. Meaning possibly jump time or something.
That is what you are looking at I am afraid.
That may not have included the Catt Converters. So you may want to check into that. If they did, then it was not from a Nissan dealer and they are after market Catts causing the Catt Codes.
At the same time, the intake timing codes could certainly be off a tooth or two. Which would not run bad one tooth off, you would just have a lack of power. Which could be close to what you are experiencing. But that could be determined by monitoring the intake timing operation with a scanner at idle.
I will put you in for a refund.
