Nissan Repair Questions? Ask a Mechanic for Answers ASAP
GreetingsCustomerand welcome to JA! I will do my very best to assist you with your problem.
You have to replace the crank sensor to resolve this issue. Normally you get a crank sensor code as well. Normally the crank sensor will resolve the issue.
If this is the 2.5L, the sensor is located in the back of the engine along side the rear engine mount on the drivers side. This is where the transmission and engine meet.
Hope this helps!

I am ready when u are
Hello just got home from work . I have a scan tool it gives freeze frame data and everything. that how i know it had a code of po725 and po335
Welcome back, so it did have the P0335 as well. So on your tool can you see the engine rpms when the car is running on it?
OK, well, I think wither the sensor is not cutting it or there is some kind of wiring issue to the ecm. You should see engine speed on the scan tool. If it is capable of live readings, no rpms would mean no crank signal. So, when you can check it out.
Also, really check the connector as they can be a pain to get back on tight.
I have also seen the pins pullout of the old sensor and get stuck in the harness.So if you still have the old sensor,make sure all of the pins are still in it and not stuck in the wiring.
/As in it is not an option on the scanner or it is not showing up
ok, so this is a code reader not a scanner.
I suspect we are going to have to go with a nissan crank sensor and recheck the connectors.
If you don't have the car back together yet inside we can use the volt meter to check some wire still to.
At the crank sensor we can check for power and ground, then if you have them we can check for continuity on the sensor signal wire.
Should have battery voltage on the Red/Green wire and continuity to ground on the Black wire
Well, this is what you need to check at the sensor end. I will send along another digram like I did last night for checking the signal wire
can u check for continuity on the senser
Sorry to leave you hanging man! wife just got home from work,
here is the sensor test
hello I dont think i have a green tab my disconect from the senser is black .but any way i dont have time to work on it today. i have my grandchildern her from out of town .there here for my other grandchild birthday tomorrow.so in joy your weekend.well i check the code again and now it say pi340 camshaft sensor
yeah, won't start with a bad cam sensor. It is safety to keep the car from having the valves and pistons hit. It can't tell where the timing is without the cam sensor. Here is the location of that one. Same type of connector on it.
Here is the picture. This is the rear engine mount and the crank sensor is right next to it. This is the view from the back side of the engine
right, but did you install it in the back side of the engine or in the head?
They look identical, but read differently
well i took the car in because i couldnt reach the sensor .but that was the problem.thank u for all your help.
