Code P0440: Looking for Purge Solenoid

Postby ambient spark » Sat May 13, 2017 4:26 pm

Hi all.

Just got check engine code p0440. Google search suggests:

Possible Causes of P0440 Code

A Leak in the System
Faulty Purge Solenoid (This is the valve that lets the fumes into the engine)
Faulty or loose fuel cap
Faulty or Loose NVLD (This is the sensor that senses whether the system is working or not)

Less Common Causes

The Computer
Leaky Fuel Tank
Bad Charcoal Canister

So, A new purge solenoid is just 20 bucks or so so I'll replace it and see what happens. Anyone know where this part is located? looked but found nothing.

Also, what is an NVLD???
