P1444 NISSAN -

Question

P1444 - Purge Flow Sensor Circuit Low Input  and P0325 Knock Sensor Circuit Malfunction Bank 1 or Knock Sensor codes appear. What do these mean, and how can I repair  them?

Answer 1

The P0325 is such a small code, it's usually on most Nissans when you check for codes. It doesn't turn the check engine light on and isn't a factor.

The 1444 code is for the purge control solenoid. This is located up on the manifold and opens when called for to pull the fuel vapors out of the canister.There are a couple of factors to determine the cause of the code. First, power to the solenoid, then check for signal. I can't get into specific wires because i have no idea what yr and model this is.If the solenoid is working properly,then the next part to check is the pressure sensor. If the sensor isn't reading right, then the ecm doesn't see a voltage change and assumes the purge solenoid is the problem.
