A couple of things Mike: 1) the crankshaft position sensor code is going off causing check engine 2) in reverse gear, the transmission doesn't engage occasionally, with what sounds like an abnormal spinning/light grinding noise... then disengaging the gear and re-engages seems to solve the problem every time
JA: Does the light stay on, or does it blink?
Customer: Light stays on. My mechanic said I should probably replace the sensor at some point, because otherwise it may go bad at an inopportune time, and not allow me to start the vehicle.
JA: What is the model/year of your Nissan?
Customer: 2000 Nissan Frontier
SE, manual transmission
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I am thinking I'll have the mechanic replace the sensor, if it's absolutely necessary.
JA: Anything else you think the mechanic should know?
Customer: Nope, nothing else at the moment.
