How to fix: P0340 code, VDC on, SES on, and SLIP on
 

n00b car guy here...been trolling this forum and others when I needed help, now I can finally contribute.

Last week my car 03 coupe threw a P0340 camshaft position sensor (Phase) bank one error. It had a hard time turning over and starting. The VDC, SES, SLIP lights were all on. Sometimes I can drive a few blocks before my car just loses power. Infinitiparts and Riverside Infiniti only lists their sensors as right or left, not bank one or bank two. From other postings, I was misinformed that bank one was the camshaft position sensor left. WRONG! Oh well, I replaced it anyway and gave me a reason to clean my throttle body.

P0340=Camshaft Position Sensor Right. It's connected to a green connector next to the firewall.

+1 for good information :D

Hey mikev80,

I've had the same problem on my sedan. I did the same, replaced the cam sensor and bingo, no problems at all now. It's annoying that it went bad in the first place. I have a thread on this as well.

I just replaced the same sensor on a coupe yesterday here at work. Bank 1 is the left side if your standing in front of the car looking at the engine. Cylinders 1,3,5 are on your left and 2,4,6 are on the right. :)

Good stuff. Thanks for the post!

Most annoying part was not knowing whether bank one is right or left. Next annoying DIY, replacing my door actuator, had the part for 3 months now :)

so i guess bank 2 would be on the right side if i was standin right in front of the engine?! coz my lights just turned on as well..

how to remove wiring harness from camshaft sensor
 

I have the dreaded P0340 error on bank 1 with my camshaft position sensor.
I am going to replace both sensors for the camshaft, since part store gave me the wrong part and I have already started on the driver side with the angled sensor. Anyways, I am having an extremely difficult time getting the harness to come loose. I see that there is a green clip that has to be dispressed and then you are supposed to pull back. I have also pulled the sensor out of the cylinder head with the harness attached and tried it that way, however I figure having it anchored securely in the case is the best way to remove. However, it is a PIA and will not come loose. Anyone else have an issue with this and how did you overcome it. I need to be careful since it is electrical and do not want to disrupt the electrical contacts of the harness. I imagine I am going to have the same problem when I get over to the bank 1 sensor which is on the passenger side. I really wish the engineers would design these cars with the mechanic in mind. Fat chance.. right???? Any help will be greatly appreciated.

Just had the same problem- SES , VDC and slip lights all came on and car shut off engine twice in traffic and started back up and ran a little rough. The sensor replacement fixed it all but costed $250.

Just had mine come on today, with all three lights mentioned. My car is a 2003 coupe, with 113k miles. Runnning ok, slow starting though. Autozone pulled codes and am showing P0340 (bank 1 cam sensor) and P0327 (bank 1 knock sensor)

I read the knock sensor can go bad without noticeable signs and wont illuminate a check engine light. Funny they would both be on the same side and I just changed oil this weekend.

So to be sure, Bank 1 is understood to be passenger side, correct?

Bank 1 = passenger
Bank 2 = driver

In for future reference.

i have an 03 sedan after the belt that goes to the ac compressor broke and i replace it. it wont crank untill after a few tries and the slip, traction and check engine came on soon too.. once it starts it runs fine. it just wont crank right it turns for a few seconds.. could it be the cam sensors or crank?

Need to replace mine today.

lolz, mine is 07 G35s sedan, 3 lights came on after installed the short ram intake, It was read code P1233 at bank 2, which I think the throttle body is something wrong? I need advice on this pls people...
