Hey gurus! I have a 2000 Camry LE and trying to fix a P0446 and P0450 code. For the P0450 code, I see it's the "vapor pressure sensor". Google'ing around I see there is a sensor at the firewall, and I guess there is one on top of the gas tank as well? Are there two sensors? Or do I have the name of the part wrong?

Thanks!

 

The sensor is mounted to the charcoal canister. Canister is located under the car ahead of the rear suspension arms.

Canister looks like item in link below:

Thanks for the reply! So is this a vapor pressure sensor as well?
We already had the canister replaced and I believe it came as a unit with a sensor and solenoid on it as well, so trying to figure out what's left to change out.

Appreciate the help!



The sensor

 

P0450 can be

A crack in overflow valve, located on top of fuel tank.

Vapor pressure sensor or wiring.

Computer.



P0446 can be

Vacuum hose leaks, plug, etc.

VSV or wiring issue for VPS or EVAP.

Crank in fuel tank over flow valve

 

Below was for one of my other Camry's. The 2001 has the sensor connected to the charcoal canister.
The vapor pressure sensor is mounted on top of the fuel pump assembly. The sensor on the fire wall is the manifold pressure sensor. The thing with a plug on the charcoal canister is a switch, I can’t remember which one.
