When it comes to the Ford P0320 Code, it can be a frustrating and confusing experience for any vehicle owner. The P0320 code indicates that the ignition/distributor engine speed input circuit has malfunctioned, and a series of erratic profile ignition pickup (PIP) pulses have occurred in the crankshaft position (CKP) sensor signal. This issue can have a variety of causes, ranging from electrical problems to arcing secondary ignition components, and can be difficult to diagnose without the help of a professional. In this article, we will discuss the common causes and potential solutions to the Ford P0320 Code.
Causes and Solutions to the Ford P0320 Code
| Cause | Solution |
|---|---|
| CKP+ circuit intermittent open (VR type) | Check the wiring and connections for any damage or corrosion. |
| CKP- circuit intermittent open (VR type) | Replace any damaged parts. |
| CKP circuit intermittent open (Hall effect) | Check the CKP sensor for installation errors. |
| VREF circuit intermittent open (Hall effect) | Check the CKP sensor for any damage. |
| Arcing secondary ignition components (coil, wires and plugs) | Replace any damaged parts and ensure proper connections. |
| On board 2 way radio transceiver | Check for any radio frequency interference or electromagnetic interference from an external source. |
Intermittent Open Circuit
The P0320 code is often caused by an intermittent open circuit in either the CKP+ or CKP- sensor circuit. If the wiring is damaged or corroded, it can cause a break in the circuit and cause the P0320 code to be triggered. To fix this issue, inspect the wiring and connections and replace any damaged parts.
Hall Effect Sensor Errors
The Hall effect sensor is used to detect the position of the crankshaft in the engine. If the CKP circuit or VREF circuit are intermittent open, it can cause the P0320 code to be triggered. To fix this issue, check the CKP sensor for any installation errors or damage.
Arcing Secondary Ignition Components
The P0320 code can also be caused by arcing secondary ignition components, such as the coil, wires, and plugs. This is often due to a loose connection or worn-out parts. To fix this issue, replace any damaged parts and ensure proper connections.
Radio Frequency Interference
In some cases, the P0320 code can be caused by an on-board two-way radio transceiver. This can cause radio frequency interference or electromagnetic interference from an external source. To fix this issue, check for any interference or interference from an external source.
Conclusion
The Ford P0320 Code can be a frustrating and confusing experience for any vehicle owner. It can have a variety of causes, ranging from electrical problems to arcing secondary ignition components. To diagnose and fix the issue, it is important to inspect the wiring and connections, replace any damaged parts, check the CKP sensor, and check for any radio frequency interference. With the right diagnosis and repairs, the Ford P0320 Code can be resolved.
