This answer was rated:

hello my name is XXXXX XXXXX have a nissan altima 2006 2.5 i just did the heads and timing chain plus camshaft chankshaft done i would like to no how come my car is loosing pressure its like its pulling
i had it read the codes saying p0075 p0335 p0725 i would like to no why please

Jay :

Hello and thank you for using JustAnswer.com

Jay :

These codes P0335 and P0725 are both due to the Crank sensor

Jay :

The Crank sensor is located on the back side of the engine block.

Jay :

This is a major signal to the computer for the car to run as well as the Cam sensor

Jay :

Both the Cam and Crank sensor are the same part.

Jay :

I always recommend you replace them both, cause when one fails, the other follows.

Jay :

But do not replace these with sensors from your local auto parts store.

Jay :

After market sensors never work right.

Jay :

When it comes to electrical parts stick with the dealer.

Jay :

Here is a image of the parts location. This is a 2.5 I had removed doing a engine. I took pictures of this to show the location of the sensors

Jay :

Thanks Jay!

Jay :

Oh the P0075

Jay :

That is a intake timing code.

Jay :

I would look at the intake timing sensor as a possible issue. Start with checking oil level. But to determine the actual issue with the intake timing, and scanner is need to perform the proper diagnostics
