Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Greetings Sir or Madam and welcome to JA! I will do my very best to assist you with your problem.
Start by replacing the crank sensor.This will resolve the 725 and the 335. Then clear the codes and see if the 507 comes back.If it does, you will have to perform an idle relearn on the throttle body. The crank sensor is located on the rear of the engine where the engine and transmission meet. You have to get at it from the top of the engine.It is right about where the rear engine mount connects to the engine.
Hope this helps!
