Good afternoon, do you have a check engine light on?

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I am getting code p0335 for crank sensor
Customer reply replied 1 year ago
I have checked and replaced cam and crank sensors the crank sensor is getting ground, 5v power and is sending a5v signal when engine is turning, the cam sensor is getting ground, a 12v input, and is giving a 10v signal when engine is turning. I have checked all wires back to the ecm and I am getting the same results there
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

Recheck signal voltage on the crank sensor Verify battery voltage to the crank sensor on the Red/Green wire. Verify ground for the crank sensor is good on the Black wire - look for 0.05 volts or less.
. Should be 8 to 10 volt square wave when cranking. Check to see if the sensor recall has been done. If not, do this first, #NTB01-081. Voltage drop powers and grounds at the ECM and replace if they are good.

Customer reply replied 1 year ago
I have a 5v on red/green wire and I have a good ground and I have a 5 v wave on pink wire when cranking. Should there be 12 volts at the crank sensor? Also how would I find out if the sensor recall has been done?
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

It should get 8-10 volts when cranking this means it is not getting what is needed to start. Very good chance you have a bad ECM as you have already replaced the sensor. You would have to contact mazda to check and see what recalls have been performed. See attached recall letter.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
Could I run a temp 12v wire to the power input on the crank sensor to see if it will start
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

No that will do damage to the ECM. The voltage from the other wire is correct so this is either an software issue wiring issue (wire between the ECM and the crank sensor) or the ECM has failed not giving you the 8-10 volt square wave signal. Attached wiring diagram so you can see for yourself. Sometimes we can fix things easy but other times it is a issue like this with no quick fix unless the wire is damaged going to the ecm.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I appreciate all your help but I'm having trouble understanding. Does the green/red wire supposed to have 5v? I have checked it at the crank sensor and the ecm both have 5v. Should it be higher because the cam sensor has 12v. Also the diagram u gave is different than my car it has the same plug but different wire layout may just have been a generic diagram I'm not sure
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

The red green wire should have battery voltage.

Ask Your Own Nissan Question
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

Also the wiring diagram should be the right one. It is for the 2003 nissan sentra with 1.8

Ask Your Own Nissan Question
Customer reply replied 1 year ago
My car is an 04
Customer reply replied 1 year ago
Also did you get my first message about the car sitting for 3 yrs and I just installed this engine.
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

No for some reason I did not see that. Well that helps alot. You need to make sure the new engine and ecm match. If not you will need to get the dealership to program and sync the cam crank and ecu. Thats the reason it is not working.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I asked the dealer and they told me it shouldn't need programming, that the new engine should be a direct bolt in and start up. I was having issues with the car not running right before engine went out, then it sat for. 3yrs
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

I really do not see any other possible cause for the voltage coming from the ECM to be incorrect other than the programming or faulty ECM.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
Ok I'm going to check with dealer again Monday on the programming and look for a ecm to swap it out in the mean time. I'll let you know.
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

Without an actual lab scope anything you get on the yellow wire will be hard to know for sure if it is correct but the other wire should have 12v on it but you are getting 5v unless the wire has a bad connection it is the ecm here

Ask Your Own Nissan Question
Customer reply replied 1 year ago
my signal wire is pink, could you get a wiring diagram for the 04?
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

Just did it is the same.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I'm sorry I keep saying 04 it's an 05
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

Tried an 05 to in 2002 it has a red wire but no pink

Ask Your Own Nissan Question
Customer reply replied 1 year ago
On my crank sensor plug I have a green with red stripe (5v w/key on) pink (0-5v while turning engine by hand w/key on) and black with white stripe (ground). I traced them all the way to ecm plug and they are the same color there.
Nissan Mechanic: C. Walker, Jr., Auto Mechanic replied 1 year ago

That is very odd, my manuals are from the manufacture so they should be identical. I am going to opt out and see if another expert can figure this one out as maybe i am missing something here.

Did any parts have to be swapped when installing it because they were not correct?

Ask Your Own Nissan Question
Customer reply replied 1 year ago
No, everything was exact, I swapped the cam and crank sensors when it wouldn't start but that's all.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

Are you using the original crank sensor now from when the car was running?

How and where are you testing the signal from the sensor?

Customer reply replied 1 year ago
Testing with a volt meter near plug, with key on, I have also tested the same wires near ecm plug with the same results.

Does it change when you remove 10 amp fuse 36?

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I can not find a fuse 36, checked under hood and inside. Am I missing it?
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

It's in the box under the hood.

Are you positive you supplied the correct VIN? Your wire colors don't match either, as well as the sensor's reference voltage as mentioned previously.

Ask Your Own Nissan Question

Do you have battery voltage on the green/white wires at the coils while cranking?

Ask Your Own Nissan Question
Customer reply replied 1 year ago
10-11v
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

Have you checked crank sensor output directly at the ECM connector?

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I probed the wire on the backside of the ecm connector and have same reading
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

A labscope should really be used, but if it's setting a P0335 yet crank sensor signal is present at the ECM then that wouldn't leave anything but the ECM; however it's failure would be unexpected. I question whether the crank tone wheel is correct and the engine is from the correct year.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
The tone wheel is internal on this engine, is 5v the correct amount voltage for feed at the sensor?
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

Not according to the factory service information. The service information shows the sensor receiving battery voltage from the main relay, but what you're describing is a 5v reference from the ECM.

Ask Your Own Nissan Question
Customer reply replied 1 year ago
I guess I'll try the ecm, that's the direction I was heading anyway.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

Good luck with it!

Ask Your Own Nissan Question
Customer reply replied 1 year ago
Can you tell me the part number for the ecm?
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 1 year ago

My catalog narrows it down to eight possible part numbers but I'm not able to narrow it any finer. If yours doesn't have a part number label then I would recommend having your dealer look it up by VIN.

MEC63-270B1 is the number on the one in the car, is that one of the eight you have listed?
