DIY: cam position sensors
haven't seen one of these but seen a few questions on this. so ill try to explain it this is my 1st DIY thread so bear with me.
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

It helped a lot! I took of my airbox and intake and waited for my engine to cool down. Turns out that Nissan sold me the wrong part. They gave me the one for Bank 1, not Bank 2. Looks like they're different enough for it to not work...
Oh well, at least I didn't have the manifold off already.

Has anyone experienced start up problems after the DIY. Did the DIY which went great but when I start the car everything is fine (no service engine light, slip light or VDC) then later the idle drops and engine shuts off with only the battery light on. I restart it no problem but same thing happens, now when I give it gas or a slight touch on the pedal the engine stays on. Anyone might know the cause?

Awesome DIY thank you so much. I was able to use this site (1youngowner's post) to diagnose my problem and then use this DIY. It really is almost as easy as it looks and it will save you time and about 300 from the dealership. Also a tip that I found while i was doing it, if you only have to replace bank 2 (driver's side) then you can leave on the lower part of the plenum.
