Hi e_lockley. The description for that P1665 code is EVAP Vent Solenoid Control Circuit Conditions. It refers to the circuit (electrical) of the solenoid.

Do a proper diagnosis, don't just replace the solenoid because the problem may also be with the wiring and connectors leading to the solenoid. Grab a repair manual and do it yourself or ask your mechanic to verify that the part has failed before replacing it.

Good luck. You may also want to read up on another P1665 case here - http://www.obd-codes.com

Service engine light stays changed gas cap done smoke test replaced oxygen sensor


Code 449 is for a defective vent valve solenoid. The engine computer can not open or close the valve or can not tell if the valve is operating.
The valve/solenoid would need to be tested and you will probably need a shop manual to get the testing procedure.

1st code p0440, then code p0453 then p0452 now p0446


This problem is out side the gas tank , has nothing to do with the fuel pump or fuel level sending unit inside the gas tank .DTC P0446 EVAP Vent Solenoid Valve Control System . Do you know anything about automotive evaporative emission system ?
Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc

This DTC tests the evaporative emission (EVAP) system for a restricted or blocked EVAP vent path. The control module commands the EVAP canister purge solenoid Open and the EVAP canister vent solenoid Closed. This allows vacuum to be applied to the EVAP system. Once a calibrated vacuum level has been reached, the control module commands the EVAP canister purge solenoid Closed and the EVAP canister vent solenoid Open. The control module monitors the fuel tank pressure (FTP) sensor for a decrease in vacuum. If the vacuum does not decrease to near 0 inches H2O in a calibrated time, this DTC sets.

There is some sort of diagnostic code stored in either the ECM(engine computer) or TCM(transmission computer).There are many sensors and solenoids and other data parameters that can cause a codes to set other than just the oxygen sensors.You will need to have the code(s) pulled to know where to start.

P1443 code problem. How do I fix this?


P1446 - EVAP Canister Vent Control Valve Close
EVAP canister vent control valve remains closed under specified driving conditions.

This solenoid valve responds to signals from the ECM. When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.

This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP Control System (Small Leak) diagnosis.

The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

About the possible causes that your must solved:
- EVAP control system pressure sensor and the circuit
- Blocked rubber tube to EVAP canister vent control valve
- EVAP canister vent control valve
- Water separator
- EVAP canister is saturated with water


Hope this helps.

Try disconnecting your battery for 15 minutes...then re-connect. This will reset all of the solenoids to factory specs...and will clear the engine light. If the engine light comes back on then you should try to get diagnosed at a free diagnosis service shop...you may need to call a few. Hope this helps.

'99 olds 88 diagnosed PO 446 evap vent control problem


Your code means:

P0446 onepx.gif EVAP Canister Purge Vent Blocked

Some of the possible causes:

EVAP vent fresh air hose is clogged, kinked or restricted
EVAP Vent solenoid is contaminated, damaged or has failed
FTP sensor is out-of-calibration, damaged or "skewed"
PCM has failed

All tough thing for a lay person to check. You don't have to take it to the dealer, any repair garage that has the proper equipment can fix this for you.
