Toyota T100 OBDII Code P0450 - Pressure Sensor Malfunction

So, I need to get this fixed on the cheap...I can do the work, but I can't diagnose the problem. Do I need to replace the charcoal canister? Anyone out there run into this code and have it fixed? Any ideas on what the problem could be before I go and by expensive parts.

P0450 deals with the Vapor Pressure Sensor, in the fuel tank vapor circuit. Buying a charcoal canister would not cure this.
Go to a Toyota dealer and tell the parts guy that you want a
Vapor Pressure Sensor.
It is on the vapor line, before the charcoal canister.

After you replace the sensor, remove the EFI fuse to clear the code.

I hope that this answers your question.

A garage checked my "ON check engine light". They replaced the EGR and EGR solenoid. These parts are side by side on a 2001 Toyota Camry. They said they also cleaned the injectors,intake manifold, and fuel lines. $600 dollars later and two days the light came back on. The auto zone said the light was reading EGR again. When the same garage went to slap a sticker on the car for inspection they said a different code showed of P0401...any thoughts what next to check? Thank you

Charcoal canisters aren't cheap. If you got a quote from a garage. This is cheap. not your problem though. Brought it to where I work and it was the problem, true problem, the part would cost more than $400. I replaced 1 canister. I have fixed all the rest of them. They are plastic.

Can't fill the gas tank, I had the check valve replaced in the gas line and it work once and now it's back to not letting me fill it. I unplugged it but would like it to work. Any ideas what it may be?


fuel vent Charcoal canister will make it difficult to fill the gas, this canister vents the gas tank and if you overfill the tank then it screws up the Charcoal canister and will need to be replaced, I just found an old canister from the used parts place and had my mechanic replace it, went directly to the gas station and presto no more problem filling gas. DO NOT overfill your tank after replacing canister!

Replaced the codes that the ECM was throwing out and car still runs the same


You Cleared all data in the pcm

You didn't replace any codes

The canister & the 3 cop coils were tested HOW?

They failed a test & thus needed replacing?

Apparently not as you still have the came OBD 2 Codes

So you now need to start over & I suggest a repair shop

If that work was done by a shop,chose an other as you paid
for nothing as you know.

Bottom Line----Never diagnosed the fault codes or found
the real issues.

Please GeoffW1 this are the fualt code diagnose from my toyota camry 1999 model v6 engine FAULT NUMBERS- 1.( p0110 ) 2.( p0135) 3.(p0450) 4.( p1410) 5.(P1411) please i need their locations and...


Sorry, I never noticed this post, for some reason I did not get an email from Fixya. If it is not too late..........
p0110 is the Intake Air Temp sensor or its wiring connector at fault. This is located at the side of the air cleaner housing.
p0135 is a fault in the No 1 oxygen sensor in bank 1, or its wiring connector. This thing is located in the exhaust manifold under the sheet metal shield at the front of the engine
p0450 is an evaporative emission system pressure sensor fault. Many people recommend replacing the fuel filler cap gasket before going further with this one

http://repairpal.com/OBD-II-Code-P0450



p1410 and p1411 indicate an EGR valve malfunction, and it may be enough to simply clean and check it, located on the engine next to the firewall. Also check the vacuum modulator and Vacuum Switch Valve, as shown here p46, 146, 152, 190
