DTC P0320 - Ignition/Distributor Engine Speed Input Circuit
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2018 Lincoln Navigator, 2018 Lincoln MKZ, 2018 Lincoln MKX, 2018 Lincoln MKT, and 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
P0320 - IGNITION/DISTRIBUTOR ENGINE SPEED INPUT CIRCUIT
| Description: |
This DTC sets when several erratic profile ignition pickup (PIP) pulses have occurred in the crankshaft position (CKP) sensor signal within a calibrated time period when the camshaft speed exceeds the equivalent speed of engine idle. |
| Possible Causes: |
- CKP+ circuit intermittent open (VR type)
- CKP- circuit intermittent open (VR type)
- CKP circuit intermittent open (Hall effect)
- VREF circuit intermittent open (Hall effect)
- SIGRTN circuit intermittent open (Hall effect)
- CKP+ circuit intermittent short to voltage (VR type)
- CKP- circuit intermittent short to voltage (VR type)
- CKP circuit intermittent short to voltage (Hall effect)
- VREF circuit intermittent short to voltage (Hall effect)
- SIGRTN circuit intermittent short to voltage (Hall effect)
- CKP+ circuit intermittent short to ground (VR type)
- CKP- circuit intermittent short to ground (VR type)
- CKP circuit intermittent short to ground (Hall effect)
- VREF circuit intermittent short to ground (Hall effect)
- SIGRTN circuit intermittent short to ground (Hall effect)
- CKP sensor incorrectly installed
- Damaged CKP sensor
- Incorrect, damaged or corroded connections
- Arcing secondary ignition components (coil, wires and plugs)
- Arcing relays or other high current devices (cooling fan or starter motor)
- On board 2 way radio transceiver
- Radio frequency interference or electromagnetic interference from an external source
- Incorrectly grounded high power aftermarket equipment
