OBD II Code PO445 Evaporative Emission Control System Scionlife com

whats the code??

Code 445 is for a problem with the EVAP purge control valve or solenoid. The valve allows fuel vapors to go from the gas tank to the vapor canister.

code P105 is manifold absolute pressure barometric pressure circuit. code P0445 evaporative emission system purge control valve circuit shorted. code PO720 AT output speed sensor circuit open or short ground.HAVE MANY CODES COULD BE ECM FAILING HAVE DEALERSHIP CHECK OUT ECM.ECM COULD HAVE SHORT OUT PC BOARD.

P0442 - Evaporative Emission Control System Leak Detected (small leak)

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code P0442 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal

Possible Solutions: with a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses



P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted.
Possible Solutions: with a P0445, the most common repair is to:
* Bad or loss contact wires
* Check harnesses, replace it


Hope helps (remember to rate this).

P0445- EVAP purge control circuit fault!! Check your gas cap, this will cause insufficient vacuum activating the SES indicator. Check the following

a) Absent or tampered fuel cap.

b) De-linked or faulty fuel tank pressure sensor.

c) De-linked, damaged, pinched, or blocked EVAP purge line.

d) De-linked or erroneous EVAP canister purge valve.

e) De-linked or incorrect EVAP vent solenoid.

f) Open ignition feed circuit to the EVAP vent or purge solenoid.

g) Tampered EVAP canister.

h) Leaking fuel sensor assembly O-ring.

i) Leaking fuel tank or fuel filler beck

p0441: Evaporative Emission Control System Incorrect Purge Flow;
A code P0441 could mean one or more of the following has happened:

Bad vacuum switch

• Broken or damaged EVAP line or canister
• Open in PCM purge command circuit
• Open or short in Voltage feed circuit to Purge Solenoid
• Faulty purge solenoid
• Restriction in EVAP solenoid, line or canister
• Corrosion or resistance in purge connector
• Bad PCM
