Mit Outlander 2003....replaced the head and waterpump and now getting two codes P0335 and PO340 several weeks later.....timing is right on....and car runs fine but won't pass with lights on.......

Your camshaft sensor is shot. I had the same problem on my 03 coupe. There are two camshaft sensors. They are located on the back side of each cylinder head. My 1st one went out and I replaced it and then the other went out about a week later. The sensors cost roughly $70 each and aren't that difficult to change. Hope this helps.

Hi. It could be the cam adjuster or the Timing chain stretched.

waterpump and thermostat.

check the security of both positive and negative connections

it is very important, if the belt fails it will severly damage the engines valves and this repair will cost $1000's

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.

Hi, I found a couple of good articles on those codes. Rather than just copy and paste here are the links:

P0340 - Camshaft Positio Sensor Circuit Malfunction

After the new sensors are installed and the code still comes back, replace the timing chain. They have been known to stretch and cause the P0335 code on these engines.

I think you could use this manual method instead.. My nephew who is a full time mechanic uses it
most of the times, and all mechanics
look up to manuals. It's very easy he gets it from. www.reliable-store.com
