I made a thread on this myself.

Heres the easiest way to get those cam sensors unplugged:

Do I dare put a cheap aftermarket sensor in instead of an OEM? Delta of $100

edit- found an oem on eBay. Maybe counterfeit but I’ll give it a shot.

I tried those on my car. Theyre counterfeit sensors in fake Nissan packaging.

I had to change mine out again after a few hundred miles.

 

Dang. Thanks for the heads up. I’ll send them back.

 

You are a rockstar! Thank you so much for the video.

 

Ok, so replacing the (drivers side cam position) sensor cleared the code but now the car won’t start at all. Good battery. Just a single click but no cranking. The starter is also less than a year old.

Any ideas before I give up and tow it in? TIA.

 

If your battery is 100% good then the next most likely culprit would be the starter itself. Its not uncommon for new starters to crap out. Try banging on your starter with a pipe. Sometimes it works.

Cam sensors have nothing to do with preventing the engine from cranking.

 

Just to follow up, you were right. The starting issue was unrelated and just a coincidence. Bad starter plus intermittent battery terminal failure put me in neophyte debugging hell. Newish starter, so parts covered under warranty at Firestone.

As for the eBay parts, they authorized an immediate refund and said keep ‘em. I suggested they remove the words “oem” from their listing when they’re such obvious fakes.

 

A lot of disreputable companies have literally named their company "OEM Equipment" and stuff like that. Anything that's actually Nissan OEM stuff will be in a bag that says NISSAN Genuine Parts. I know buying stuff like this on eBay can be tricky and that's why I usually stick to actual online dealerships like infinipartsonline.com which is just the online marketplace for an actual dealership in Arizona.

For cam/crank sensors though you can just buy specific Hitachi part numbers and that's fine.

 

Hey all,
working on my 03 sedan and I damaged the connector on the driver side cam angle sensor. When plugging it in now, it still makes the click like it should, but the connector pulls right off of the sensor. This happened as part of a valve cover job, and I'm having a no start condition despite everything looking correct. I'm assuming this is the culprit, but I was wondering if anyone has had a broken connector like this and still managed to start the car .
thanks all

The harness is readily available through online vendors and most parts houses. Solder/splice in a new one.

 

What's up cleric. Quick question so the OP said to test for a open circuit on the sensor. My question is 1.Does it matter which ohm setting you use to test 1-2 prongs? 2.so if I get no reading at all from 1-2 does this mean it's a open circuit? And I should atleast get some type of resistance reading? TIA you're the GOAT.

 

Just pick the highest range setting i f it's not an auto-ranging meter.

First check the meter and see what the screen reads without touching the leads together, it's usually zero or "OL out of limit". Now touch the probes together, it should read like 1 or 2. Put the probes on the pins of the sensor, it should NOT stay out of limit/0, it should give you some kind of change in reading.


Probe 1-2, 1-3, 2-3.

 

Yup.. that explains it all .. I get no change at all when I touch the probes.

 

Just to verify try changing the range on your meter, try 200 and 2k if you have it.
