My 2003 sentra was running just fine but did need a alternator so I replaced it. The car was running fine for about two days. I started the car and set at idle for about 15min and it just cut off. I tried to start it but it just crank no start. Scan it and the for the code crank shaft position sensor plus p1122 and p1126 is what I got. I replaced the sensor and the car started just fine and idles fine. However when I press the gas pedal it only rev up to about 1500 to 2000 rpm. Note: I still have the codes p1122 and p1126. I replaced throttle position sensor and nothing changed. What should I do?
Nissan Mechanic: Chris(aka-Moose), Nissan Technician replied 1 year ago
Quite often this is due to wiring breaks and chaffs in the wire harness for the throttle body, can you check that? At the throttle control relay, there should be voltage at the 2 White/Red wiresThe Pink wire should be a ground from the ECM.The Red/White wire should be voltage supply to the ECM for the throttle motor. If voltages are good, with the key on engine running the voltage should be 0 or groundedIf there is battery voltage, then the ECM hasn’t grounded the relay.Ground the Pink wire and the relay should turn on supplying the ECM pin 3(Red/White wire) with battery voltage.Once there is voltage to pin 3, the throttle motor should work. Can you do those tests? -------------------------------------------------------------------------------------On your screen at the top you should see a rating 1-5 stars and a green submit button. Please make sure to select one and press submit. I am not compensated by the website unless a customer rates. Rating only pays me from the deposit you have already made, it does not charge you more, nor close the post. Also all follow ups are free and welcome.Thanks Chris

Sorry but I am new to this wire testing thing. Could you better explain please.
Nissan Mechanic: Chris(aka-Moose), Nissan Technician replied 1 year ago
In test 1 you should of gotten battery voltage your image shows 0.01 so that means fuse 41 is blown under the hood or the wire is broken.

The wire seems to be fine.
Nissan Mechanic: Chris(aka-Moose), Nissan Technician replied 1 year ago
If the wire is fine though your still not getting voltage on this wire indicated fro test one then the fuse ha to be bad or your checking the wrong wires.

Ok I didn't get a voltage reading on the red wire when it was unplugged from throttle but I poked a hole in it and test it while it was plugged up and got a reading of 5.06.The fuse was fine btw.
Nissan Mechanic: Chris(aka-Moose), Nissan Technician replied 1 year ago
Maybe it will be easier for you to follow the code tests and wire diagrams below so you know the outcome and result for each test.https://dl.dropboxusercontent.com/u/90220402/1122.pdfhttps://dl.dropboxusercontent.com/u/90220402/1126.pdfhttps://dl.dropboxusercontent.com/u/90220402/sentra.pdf
