Code po443

code p0443 refers to EVAP canister purge valve--circuit malfunction===causes --wiring---EVAP canister purge valve--ECM

code p0451 refers to EVAP pressure sensor --range/performance problem===causes --EVAP pressure sensor

code p0135 refers to heated oxygen sensor(HO2S) 1 bank 1 heater control --circuit malfunction===causes --fuse--wiring--HO2S ---ecm

basically the HO2S sensor is not stable and altering the air/fuel mixture settings for the ECM and this is not being helped by a faulty EVAP purge valve and pressure sensor.

How do I clear the computer code PO451 Can from my truck

It is a evaporative emissions code. (evap system catches stores and eventually has the engine burn fuel vapor preassure from tank) It relates specificly to the vapor preassure sensor mounted on the evap canister.
There is either a open or short in the wiring to or the sensor itself, causing inaccurate readings, and thus throwing the code. Unless youve been in an accident, it is probably the Preassure sensor.
the canister is mounted directly above the rear dif

The amber engine light on my Honda Civic Si 2004 (93,000 kms) comes on when my gas tank is at the half tank mark, then two lines below half tank it goes off, and then just above the empty line it comes...

The gas tank has a sensor to monitor fuel evaporation. If it determines that fuel is evaporating from the tank, the check engine light will come on. It usually is caused by the gas cap losing it's seal. Get a new gas cap,make sure it is made for your car. That should eliminate the light.

2008 Toyota Sienna check engine light is on, diagnostic check reports code PO451. Checked the fuel cap, it is ok, anything else I can do? How can I reset so lights go off?

Hello and happy holidays
Fault code P0451 is a code for the fuel tank evaporative emission control pressure sensor, this sensor is located on the top of the fuel tank, the gas cap is not the problem here, as far as the check engine light goes it will reset by itself if the problem is fixed in 3 drive cycles (about 60 miles of mixed driving), to clear it you either use a scanner or disconnect the battery for 5 minutes, I do not recommend the battery method as it can cause you to loose vital settings in the control modules in the car.

Trouble codes for saturn ls2 car is showing the following trouble codes. po300, po306, po451 p2bo3 and c112b

P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.
