2005 Nissan Altima 2.5s

Question

I have a 2005 Nissan Altima 2.5s. I am getting codes p0725, p0335, and p0302. I changed crankshaft position sensor, camshaft position sensor, spark plugs, and ignition coil on cylinder 2. Both sensors oem Nissan and hitachi (oem) ignition coil. The p0302 went away but I am still getting the other 2 codes.

Answer 1

Hi there,

The 335 and 725 are both generated from the crank sensor. Couple things to look for on the sensor. Make sure that the old pins stayed in the old sensor. I have had times where when I disconnected the original sensor, the pin stayed in the harness. The other thing to look for is that the O ring didn't stick to the engine when you removed the old sensor. This will cause to large an air gap and the sensor will not read properly. If both look good then you have a wiring issue that will need to be addressed.
