they could have make the sensors the same and saved money but they didn't the only difference is the angle of the plug. and you could swap them is the grooves on the connectors weren't reversed

TOOLS: 10mm socket, 10mm box end wrench, flat head screw driver.

1. disconnect batt.
2. get to work remove intake and (engine cover 2 bolts and 2 nuts)
3. remove upper plenum
4. remove lower plenum
5. move wire bundle to access bank 1 sensor
6. remove 1 10 mm bolt and pull the sensor out
7. replace with new sensor
8. remove breather hose from valve cover (forgot to circle that one but youll see it. if you dont get some glasses)
9. remove 1 10 mm bolt and pull out bank 2 sensor
10 . replace sentor
11. re-assemly, johnny 5
12. reconnect batt.
13. turn her on.

PIC 1: Upper plenum (remove bolts(alot), nuts and 3 or 4 hoses,i think there is one one the bottom of the TB, circled)
PIC 2: lower plenum (remove 6 bolts in center, 2 nuts and 1 hose, circled)
PIC 3: sensor positions (left side = passenger)
PIC 4: sensor before removal(1 10mm bolt holds that sucker in and an "O" ring gotta wiggle it to get it out)
PIC 5: sensor after removal

Close to the radiator. You can see the radiator hose going very close to this part. It is a green colored switch. Not sure what is is connected to? It seems to me that is broken and must be replaced. but I am not sure,what it is.

Thank you for all your help.

2003 g35 coupe 6speed manual 93k miles with a 84k miles engine swapped. Motor was never opened up before as i can still see the oem gasket makers squished in place still.
SES light on
VDC light on
SLIP light on

Error code:
P0328(knock sensor high input)

P0011(variable valve timing over advance bank 1?)

P0021(variable valve timing over advance bank 2?)

P0345(camshaft position sensor "A" bank 2 circuit)

I replaced the knock sensor with a autozone one, still same codes and problem driving

I replaced the driver side cam sensor with a nissan one and problem still persists.

One thing i did find out weird, bought a oreilly cam sensor for driver side, car just cranks and not firing up. Returned it and got another one, same thing. So i went to autozone and bought one, still same results. Finally i got sick of it and went to nissan and bought one. Fires my car right up and runs. But problem jerking and not going over 2300 rpm still there.


i can unplug the driver side cam sensor and the car would actually run normally but with all the warning lights on. Just takes 3-4 seconds to start up, car never shut offed on me either, runs with the cam sensor not plugged in and still runs after plugged in with all warning lights on. Last thing i want to hear is timing jumped. And the engine sounds quiet and normal. Dont hear any chain slapping or tensioner ticking

If anyone can help i would really appreciate it.

Message me or post on here thanks
