Hello fellow forum members,

I hope you're all doing well. I'm having a bit of trouble with my 2003 Ford F-150, and I'm hoping to get some advice or guidance from the experts here. I'm a complete novice when it comes to mechanics, so I'd appreciate any assistance you can provide.

The Problem: My Ford F-150 is giving me a P0320 code, and it's causing quite a headache. The truck starts up fine, but it randomly dies, and then it won't start again for a while. The additional complexity is that the truck is set up to run on dual fuel - propane or gasoline.

What I've Tried So Far: I had a friend help me change a sensor, but unfortunately, he has since disappeared, and I'm left not knowing where to go from here.

My Questions:

1. Can someone help me understand what the P0320 code means in my situation? https://www.obd-codes.com/p0320 I found this link on the forum, but I have no idea what I am really looking at.
2. Is there a way to troubleshoot the issue, considering the dual fuel setup? From my understanding it shouldn't be a factor for this code, and The propane functionality hasn't been used in years.
3. Any advice on what I can do as a complete novice to resolve this issue?

I'm really hoping to get my trusty F-150 back on the road, and I'm open to any suggestions or guidance you can provide. Thanks in advance for your help!

 

Does this help?

 

I will check tthis in the morning thank you!

 

Looking through my truck and using that video as a reference the wires don't seem to be frayed or show signs of wear like that.

 

I would be looking to view the CKP pid
Visually inspect the crank sensor wiring

 

Sorry but what do those acronyms mean?

 

CKP is the crank sensor
PID is parameter identification data
Like the TP (throttle position) PID would display roughly .8 volts at idle and 4.5 volts at wide open throttle
Your CKP pid will have normal sensor data (for your engine)
You did not mention what motor you have but the sensor reference values are out there
You can ohm test the sensor and watch the voltage pulses with a DVOM plus check the pid
You can ohm out the wires and connector back and forth to the processor from the CKP
Good luck
