DTC 565 code. Checked sol purge solenoid by unplugging harness,

Resolved Question:

DTC 565 code. Checked sol purge solenoid by unplugging harness, hooking up vacuum guage and starting engine. No vacuum. With engine running, plugged in harness and vacuum dropped. Solenoid is functioning. Truck runs OK until after warm up. MIL comes on while cruising. Then goes off and engine looses power(dramatically) does not immediately respond to trottle input until pressing the accelerator pedal all the way to the floor. Then engine runs fine again for awhile when this whole process begins all over again. 565 is the only code I see.

1995 Ford F150 4WD automatic with 302 engine. High milage but with no problems up until now. I also forgot to mention that at first when I saw 565, I did find a cracked vacuum line between the solenoid and the intake. I replaced the line and at the same time cleaned the MAF internal wire with electronics cleaner. The problem went away for a long time but now it's back. The fuel filler cap looks OK but I have no way of checking it. The oxygen sensor is original. As I ststed earlier, when the malfunction occurrs, the throttle is momentarily non-responsive and the engine lacks power.

Here is the pinpoint test for the code.I have found that following these tests are the best way to get to the bottom of the problem.

On Board Diagnostics I A PCED

KD6 DIAGNOSTIC TROUBLE CODE (DTC) 565 OR 569: CHECK VPWR TO CANP

    • Open harness (VPWR or CANP).
    • Damaged CANP solenoid.
    • Shorted (power to ground) harness.
    • Damaged Powertrain Control Module (PCM).
  • DTC 565 or 569 indicates a failure in the CANP solenoid circuit.

    In a dual CANP system (7.0L Truck) DTC 565 refers to CANP1 and DTC 569 refers to CANP2.

    Possible causes:

  • Key on, engine off.
  • Disconnect appropriate CANP solenoid.
  • Measure voltage between VPWR at the CANP solenoid vehicle harness connector and battery ground.
Is the voltage greater than 10.5 volts?
Yes No
GO to KD7 . SERVICE open VPWR circuit. RECONNECT CANP solenoid. RERUN Quick Test.

KD7 CHECK CANP RESISTANCE

  • Key off.
  • Disconnect appropriate CANP solenoid.
  • Measure CANP solenoid resistance.
Is resistance between 30 and 90 ohms?
Yes No
GO to KD8 . REPLACE CANP solenoid. RERUN Quick Test.

KD8 CHECK CONTINUITY OF CANP CIRCUIT

  • Key off.
  • Appropriate CANP solenoid disconnected.
  • Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.
  • Install breakout box, leave PCM disconnected.
  • Measure resistance between Test Pin 11, 15, 31 or 54 (refer to pinpoint test schematic ) at the breakout box and CANP circuit at the CANP solenoid vehicle harness connector.
Is resistance less than 5.0 ohms?
Yes No
GO to KD9 . SERVICE open circuit. REMOVE breakout box. RECONNECT all components. RERUN Quick Test.

KD9 CHECK CANP CIRCUIT FOR SHORT TO GROUND

  • Key off.
  • Appropriate CANP solenoid disconnected.
  • Breakout box installed, PCM disconnected.
  • Disconnect Scan Tool from Data Link Connector (if applicable).
  • Measure resistance between Test Pin 11, 15, 31 or 54 (refer to pinpoint test schematic ) and Test Pins 40, 46 and 60 at the breakout box.
Is each resistance greater than 10,000 ohms?
Yes No
GO to KD10 . SERVICE short to ground. REMOVE breakout box. RECONNECT all components. RERUN Quick Test.

KD10 CHECK CANP CIRCUIT FOR SHORT TO POWER

  • Key off.
  • CANP solenoid disconnected.
  • Breakout box installed, PCM disconnected.
  • Scan Tool disconnected from Data Link connector.
  • Measure resistance between Test Pin 11, 15, 31 or 54 (refer to pinpoint test schematic ) and Test Pins 37 and 57 at the breakout box.
Is each resistance greater than 10,000 ohms?
Yes No
REPLACE PCM. REMOVE breakout box and Scan Tool. RECONNECT all components. RERUN Quick Test. SERVICE short to power. REMOVE breakout box and Scan Tool. RECONNECT all components. RERUN Quick Test.

I do not have a breakout box. Where could I get one? Does the throttle response issue actually lend itself to the CANP malfunction?
Expert:  Scottdagoalie replied 5 years ago.

Any Ford dealer will have a break out box.You can also check the wires to the PCM directly if you can't find a break out box. The throttle response is likely not related to the CANP unless it has an electrical issue that could be feeding through to other circuits.I suggest repairing the CANP and then retesting for throttle concern.
