2002 Pathfinder Camshaft Sensor and O2 Sensor Replacement?

[dohcser]

I did try looking around this site as well as Google to find a procedure on replacing the Camshaft Sensor but was un-successful. I am getting the following Codes.
P1140 - Camshaft Sensor
P0140 - O2 Sensor (Bank1 Sensor 2)

Any help on location and replacement as well as should I get the part from the dealer would be appreciated. Thanks in advance.

Bank 1 Sensor 2 is the passenger's side downstream oxygen sensor. Do you live in an area that does emissions testing? If not, you can ignore this indefinitely. If you want to go ahead with the replacement anyway, you can buy this direct-fit sensor from Advance Auto Parts for $52.99 before tax if you order online using discount code TRT37 and pick-up in store. Bosch is the original O2 sensor supplier.

P1140 is the passenger's side camshaft position sensor. You can swap it with the driver's side to see if the problem moves - if it does, the sensor is at fault. Page EC-527 of the factory service manual shows the locations of the two sensors.

Thank you very much for your quick response.
NJ does check for emissions and plugs directly into the OBDII to ensure there are no codes, so have to get these fixed.

Other than the Manual you referenced there is no member that documented "how to"?

This blog post is a big help, I used it when I first got my Pathfinder. I replaced both sensors using Standard Motor Products sensors and the CEL has not come back, it's been 4+ years now.

From the post it states that the camshaft sensor I need is on the Passenger side. Would that be considered "intake" or "exhaust" side?
I am looking at Rockauto:
Standard Motor Products - PC426, PC458, or PC458T

Any suggestion on other brands?

[Towncivilian]

It's the same part for both sides. I would suggest Beck/Arnley as well.

[dohcser]

Thank you just ordered both parts.
Now have to figure out how/where is the camshaft.

[Towncivilian]

The blog post I linked above shows the locations of the camshaft position sensors. The passenger side is easy, the driver's side is a little more difficult since there isn't much clearance to wiggle the sensor out.

[dohcser]

Think you meant the passenger side is more difficult. And I didn't realize the blog post was there. Thank you very much.
