Customer Question

a few days ago I changed my evap and camshaft position sensors and now my truck will not start
JA: Which particular sensor are you asking about? And have any trouble codes been triggered?
Customer: when I received the codes it was po447 and I think po345 which indicated that these 2 sensors needed replaced.
JA: What is the model/year of your Nissan?
Customer: 2008 Nisan Frontier SE
JA: Are you fixing your Frontier yourself? What have you tried so far?

Did you use a cam sensor from a parts store or one from the dealer?

Yes? was it from a parts store? Also, did the truck start and run right after you did the work?

no
Expert:  Mike V. replied 9 days ago.

Ok, thanks.

The first thing I would do is try putting the old cam sensor back in and see if the truck starts. If you used a cam sensor from the parts store it might not be working properly. Also, double check the connection for the sensor since it can be difficult to get it plugged all the way in. The evap code won't keep the truck from starting, so we need to focus on the cam sensor you installed. Sometimes the old o ring will stay on the engine as well. That causes to large an air gap and the truck won't start. If you find that the truck starts with the old sensor installed, then you will need to replace it with one from the dealer. This is usually the type of issues I see with the aftermarket cam sensors.
