2005 Nissan Altima SE 2.5L with engine code P0335

Question

I changed the sensor, cleared the P0335 code. but it came back after the second start. What else to look at??

Answer 1

Hi there,

The most common issue when the code comes back is the use of an aftermarket sensor. Also check and make sure the O ring came out of the block with the old sensor and finally, make sure you are connected tight. Due to the location of the sensor it's easy to not get the harness plugged in tight enough.
