Thanks. I replaced the bank 1 camshaft position sensor last night. The car sounds a lot better, starts up better and the engine doesn’t feel as heavy when driving. The service engine soon light was still on for a few days.
I just wanted to share exactly what was going on with the car and some of the symptoms. Hopefully it will help anyone that has this issue.
Vehicle: 2003 Infiniti G35 Coupe
Engine: 3.5L V6
Issue: Camshaft Position Sensor
One morning I got into my car and noticed that the light above the passenger seat was on. Of course I was upset because it meant that the light was on for at least 2 whole days and I was expecting the battery to be dead. The car started up fine, so I’m not sure if the light has anything to do with the issue. So after driving for about 5 minutes the car completely shut off. It was basically a moving parked car!!! The steering wheel locked so it was really hard to pull over. Thank God I was on a local street. I didn’t force the steering too much b/c that could affect the power steering. Once on the side, the car took really long to start up, I mean about 5 seconds from hearing the crank to actual startup. Usually it’s instantaneous. Now, the service engine soon, vdc off, and slip lights were on.
- The car is consuming more gas and feels much heavier i.e. the engine does not push like it used to.
- When started after several hours, only the service engine soon light is on and while driving the car turns off and when restarted the other two lights (mentioned above) turn on. Happened several times. Once the two other lights are on the car does not turn off.
- When starting the car after several hours it starts up fine and the service engine soon light is on. However, when the other two lights are on the car takes about 5 seconds to start. 5 seconds sounds like nothing until you hear you’re poor mans Ferrari turnover for that long – trust me, it’s hard to take.
I got my car checked out with a scanner/diagnosis and it returned code “P0340 Camshaft Position Sensor.” I had the service engine soon light cleared just to make sure it wasn’t the battery or something else. The car was driving perfectly fine and two days later the light came back on with the same issues.
After finding out that there are 3 sensors (driver side, passenger side and under the car near oil pan) for this car I put up some posts to see if anyone knows which one has the issue. So I waited. After receiving no replies and reading a few other posts it sounded like the driver side had the issue so I purchased it from the dealer and tried it. Same thing happened and did not resolve the problem. Dealer wouldn’t take electrical items back so I decided to ask the dealer to simply exchange the sensor for the passenger side. Thankfully he was able to do that.
I replaced the camshaft position sensor in bank 1 (passenger side) last night and it seems that the car starts up better than before and does not turn off. The service engine soon light just turned off about 2 days ago so Im hoping everything is fine now.
I just find it really hard to believe Nissan/Infiniti does not cover such a dangerous problem. I can understand that every car has mechanical/electrical issues but for a car to stop working on the road like that is unacceptable. There was a recall on this issue but according to Nissan only 18 cars were affected so I was rejected. What can you do?
Thanks for the help everyone!!!
