Where is the evap vent solenoid fuse located on 2005 nissan altima


It doesn't have a "fuse" specific to the purge valve solenoid. What he is telling you is that you need to have this circuit troubleshot. Either the PCM the wiring going to the purge valve solenoid, or the purge valve solenoid itself is malfunctioning.

This requires a scanner, a digital volt ohm meter and some knowledge of when the purge valve actuates and under what conditions.

The car must be running and operating at cruising speed before the PCM sends a command to the purge valve to operate. Some scanners have the ability to send a request to the PCM to actuate the purge valve, but that scanner is usually a dealer's or equivalent.

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.

04 escalade p0443 replace purge valve and gas cap but didn't check fuse so which fuse is it


There wouldn't be a fuse. The valve would be controlled by the engine computer. The code indicates a circuit malfunction in the purge control valve. Since a new valve didn't fix it, you would have to see a wiring diagram and follow a testing procedure with a digital volt/ohmmeter (DVOM) to diagnose the circuit. In short, you would need to buy a good repair manual for the car and become a dedicated DIY'er. Wish I had the information at hand that you need, best I can tell you is refer to a repair manual. A solenoid would only have two wires to it, a signal wire (power) and a ground wire. I don't know if anything else would be in the circuit. On older cars, it would have been a simple duty cycle solenoid-anytime the engine was running, the purge system was on.

Po446 evap vent code where is the evap vent located


Some might have an ses p0446, evap emissions vent circuit low. If you take it to the dealer they want 300-400.00 to fix the problem. GM has a service bulletin on this condition and have the updated part for 180.00, thats suppose to eliminate this issue.

Basically the problem is, the evap purge vent valve gets clogged with dirt, especially if the truck is used in dirty conditions. Well I figured there had to be a cheaper way to cure this problem.

Here it is:
1) find the location of the vent valve; its under the truck, locate the charcoal canister on the front of the gas tank and trace the vent line to the vent valve.
2) Take the bracket loose with a 5/8 wrench.
3) Spin the valve around so the side with the hole is facing you.
4) Take an air compressor and blow the vent valve out.
5) reinstall and clear the code and it's fixed.

Now I know the updated part from gm is supposed to keep the valve from clogging ever again, but why spend the money when all you have to do is blow out the vent valve every 50k-100kmi and save your $$$!
