DTC 565: Indicates failure in Canister Purge (CANP) solenoid circuit

Possible causes are:

-Damaged CANP solenoid
-Open harness (VPWR or CANP).
-Shorted (power and ground) harness.

With KOEO.

• Disconnect CANP solenoid connector located near the TPS, there should be a vacuum line in between the two throttle bodies, follow that.
• Measure voltage between VPWR CANP connector and battery ground.
• Is there voltage greater than 10.5 volts?
  
  If Yes, disconnect CANP solenoid and measure resistance of the solenoid.
• Is resistance between 30 and 90 ohms?
• If yes, let me know because it's a bit more involved, testing PCM harness resistance.
• If no, replace CANP solenoid.

 

The continuous (memory) DTC's 172 and 212 must be ignored at this time until all hard (KOEO) codes are corrected.

It sounds to me like the purge solenoid valve could be stuck open and as a result, the O2 sensor is indicating a lean condition from all the fresh air of the fuel tank entering the intake manifold.

Case in point, this is why all hard (KOEO) codes should always be corrected before the soft continuous codes after the separator pulse.

 

you can always pull apart the dash and pop out the bulbs.

i'm missing quite a few bulbs in mine, like the seat belt bulb (ps acording to state laws i'm not required to wear a seat belt.), and the ABS bulb and the air bag bulb, i was suprised when i put the truck back together i didnt have any codes lol so the enigne bulb is still in there.
