Good day
P0450 is Evaporate emission system pressure sensor/switch
the cause could be
1. short or open in the vapor pressure sensor circuit
2.vapour pressure sensor
3. ECM

You can test with the following
you can access the ECM behind the glove box. turn ignition on,backprobe the ECM connector, on A/T models, measure voltage between terminals #1 (green/black wire) and #22 (brown/black wire) at the ECM E6 connector. on M/T models measure the voltage between terminals #1 (green/black wire) and #9 (brown/black wire) at ECM E6. if voltage is 4.5 - 5.5 volts, go to the next step. If the voltage is not 4.5 - 5.5 volts, replace ECM and retest.
2. back-probe ECM connector on A/T models measure voltage between terminals #15 (red/blue wire) and #22 (brown/black wire) at ECM E6. on M/T models measure voltage between terminals #4 (red/blue wire) at ECM E5 and connector #9 (brown/black wire) at ECM E6 connector. on all models disconnect the vacuum hose from the vapor pressure sensor. sensor is located near the brake master cylinder. connect a vacuum pump to sensor. if voltage is 2.9-3.7 volts without vacuum applied and 1.3-2.1 volts with .59 in.Hg (2kpa) vacuum applied. replace ECM and retest if voltage is not as specified go to next step.
3. check for open r short circuit in the wiring harness between vapor pressure sensor and ECM. repair wiring as necessary. if wiring harness is okay replace the vapor pressure sensor.

Hope this helps

Cheers

Speedometer dont work


which engine, 1MZ? what? the engine dictates the ECU the ECU dictates what scan tool works this year.
what country, not stating that ,makes all answers wrong.
so as always, i post from USA , answers


The speedo on 95 series cars have a VSS,
and if it is dead, the PCM will be glowing the ECU and very unhappy,

so l mr. ABS 100x angry...too.. Ignore ABS for now;.
as they say first things, first.
you turn key , to on, CEL glows, (must) means PCM happy.(self checks)
you start car, the CEL goes out and stays out , does it? no i bet.
you drive, and CEL comes on , you insert the diagnostic, jumper (non IMZ engine)
and bingo CEL flashes out code for VSS dead?

code 9, code 42? others?
post your DTC error code and we CAN fix it.
OBD1: engines.
http://www.troublecodes.net/toyota/

ok , id fix the speedometer first.
sure would.
bad cable? did you test and check the cable yet?
i looked up your car at alldata.com so could you.
VSS is manditory for many ECU/PCM /TCM and ABS functions.
mandatory.
your car i think is USA car, is it? , and if YES< then is OBD2 compliant?
see list of cars below that are, (early OBD2)
so if it is , scan it after driving say 30 miles, or 5miles fast.
got P0500 that is a dead VSS.
fix speedo. now.
any scan tool made for OBd2 works on IMZ engine, here, state side.


data: OBD2: cars.
1994 vehicles equipped with the early OBD II systems include Buick Regal 3800 V6, Corvette, Lexus ES3000, Toyota Camry (1MZ-FE 3.0L V6) and T100 pickup (3RZ-FE 2.7L four), Ford Thunderbird & Cougar 4.6L V8, and Mustang 3.8L V6.

1995 vehicles with OBDII include Chevy/GMC S, T-Series pickups, Blazer and Jimmy 4.3L V6, Ford Contour & Mercury Mystique 2.0L four & 2.6L V6, Chrysler Neon, Cirrus and Dodge Stratus, Eagle Talon 2.0L DOHC (nonturbo), and Nissan Maxima and 240 SX.

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

P0450 code on a honda civic


Here is the definition.

The Code P0450 indicates that the Evaporative Pressure Sensor output value is not changing during the EVAP Monitor test and/or the operation of the vehicle. This code uses "two trip" logic, which means that the fault condition must be present during two successive cold starts and vehicle operation.
The sensor is mounted in the top of the gas tank near the sending unit. You would need to test the pressure sensor.

Hello I have a 1997 toyota Camry with 182000 miles on it. When I started my car my check engine ligth stay on. I went to Auto Zone to get it troubleshooting and a code P0450 came up it also states...


P0450 has to do with the EVAP emissions system, specifically it is a code for the vapor pressure sensor not reading correctly. It could be the charcoal canister, the pressure sensor, a bad VSV, or a bad vacuum line. There are literally several pages worth of diagnostic information to help trouble shoot this code. This is not a do it yourself friendly deal.

If I remeber correctly there was a recall on the charcoal canister but your out of the mileage warranty. I do know that if everything checks out and a problem cannot be found than your suppose to look at the number on the computer it may need to be replaced if it matches the numbers that have been updated to resolve this issue.

1997 T100 V6 has rough idle on initial start for about 5 seconds then runs fine.


You may have a head gasket issue or just need a tune up.. If you need a head gasket what is happening is just a litle coolant is leaking into the cylinder so on cold starts it causing a misfire. Get to properly diagnosed. You could be wearing out the cat.. if it keeps up then you will set a check engine light for a dead catalytic converter.

Toyota T100 OBDII Code P0450 - Pressure Sensor Malfunction


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.
