Hi everyone! A new guy here.
I've got an issue with my sporttrack. When I turn on my truck, the voltage display drops down to low and stays that way.
I bought a OBD2 code reader and got code P1451. I know the technical description is: EVAP Control System Canister Vent Solenoid Circuit Malfunction.
I also know the possible causes and possible solutions are:
Causes

A code P1451 may mean that one or more of the following has happened:

• VPWR circuit open
• Damaged canister vent solenoid
• Canister vent solenoid circuit open or shorted to ground, power, etc.
• Damaged Powertrain Control
  Module (PCM)

Possible Solutions

• Verify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery
  voltage. When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal. Output test mode may be used to switch output on/off to verify function.
• Replace canister vent solenoid

Now, I've copied this from the internet, so I only know this because I searched for it. I'm no mechanic, just a backyard one.
I've checked the wires for possible cracks and found none. The solenoid is a bit rusty, but all the wires are intact and as they should be.

What am I missing here? Am I looking in the wrong direction or???
Any help would be greatly appreciated.
Thanks,
Neil.

 

My first recommendation is to have your battery tested. Weak batteries make these Sport Tracs do all kinds of weird things!! I don't think the P1451 has anything to do with your voltage issue.
