I retrieved a few codes from my 96 and one of them was 08 07 (EVAP Canister purge control valve/ solenoid valve circuit). I looked around on the org and found a few posts that described some engine codes but i was hoping that maybe someone has had this code or knows how to deal with it. Any information is appreciated. Thanks.

 

0807
Diagnostic Trouble Code 0807 does not appear in the '99 Maxima factory service manual, and that is my principal information source. I'll tell what I know about the '99 Maxima EVAP Canister Purge Volume Control Solenoid Valve. This information may or may not apply to your Maxima.

The Evaporative Emission (EVAP) Canister Purge Volume Control Solenoid Valve uses an on/off duty cycle to control the flow of fuel vapor from the EVAP canister. Diagnostic Trouble Code 1008 is set when the Engine Control Module (the computer) detects an improper signal through the valve. The problem is likely to be in the electrical wiring, harness, or the valve itself.

Check fuse #58 (10 amps) and replace if necessary.

The CPVCSV is easy to see and reach. It is located in the engine compartment, mounted to the top of the upper intake manifold. Notice the Vehicle Serial number stamped into the firewall. Put your finger on the third-from-last number. Move your finger three inches toward the radiator. That's the CPVCSV. It has one two-wire electrical connector and two vacuum hoses.

You may test the valve. This test procedure is performed with the engine off. Remove the electrical connector and both vacuum hoses. Fasten a length of clean rubber vacuum tubing to either nipple. Gently blow through the hose. The valve should be closed and it should be difficult or impossible to send air through the valve. Now use a pair of fused test leads to provide 12 volts to the electric terminals. The polarity doesn't matter. With the solenoid energized the valve should be open and it should be easy to send air through the valve.

good luck with the max

 

Yeah that was one of the links that I found when I was looking around. My only question is, does it have to be taht valve or can it be a loose or cracked hose. His write up there kinda explains it but it threw me off when it started talking about other check engine codes. Thanks for the reply.

 

I took the valve solenoid deal off the car as that write up said but things were a little different. There were six leads, not two, and the functions were reversed, no power valve open, power, valve shut. Regardless, it looks like the valve is working. Any other suggestions?

 

Checked almost all I can think of. Is 0807 more specific than just P0443? Anyways BUMP
