P0443 Issue

Hey guys, before say anything let me say I already search for this issue, with no success in the threads you already have, no valuable information....

one guy mistakenly let something discconected, some other get some info but there is no fix in the thread, some say it's related to the cap but the information it's not enough.

I get the code, after i start the car, i remove the code and the code it's not coming again... but if i turn off the car and turn on, then i get the code...

I just wanna need to know what should i buy...

this is what the shop manual says.

Purge solenoid valve circuit problem

• Purge solenoid valve malfunction
• Connector or terminal malfunction
• Open circuit in wiring harness between main relay terminal C and purge solenoid valve terminal A
• Short to GND in wiring harness between main relay terminal C and purge solenoid valve terminal A
• Open circuit in wiring harness between purge solenoid valve terminal B and PCM terminal 2P
• Short to power supply in wiring harness between purge solenoid valve terminal B and PCM terminal 2P
• Short to GND in wiring harness between purge solenoid valve terminal B and PCM terminal 2P
• PCM malfunction

so to translate, make sure the purge solenoid valve electrical connection is ok, and then check the purge valve for an open or short.

the purge solenoid is the one right by the oil filler cap, part number Z504-18-741A
