P0321 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0321
Ignition/Distributor Engine Speed Input Circuit Range/Performance
What does the code mean? OBD-ii Code P0321 definition:
The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Engine Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms Sumptoms of OBD code P0321
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – The engine may be harder to start – The engine may stumble or stall
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – The engine may be harder to start – The engine may stumble or stall
Causes Causes of the OBD-II code P0321
– Loose wires/connectors – Faulty Crank Position Sensors – Arcing secondary ignition components (coil, wires and plugs) – Low battery charge – Powertrain Control Module (PCM) The Error code is generally activated on detection of the following conditions: The P0321 code is triggered when the signal is out of range.
– Loose wires/connectors – Faulty Crank Position Sensors – Arcing secondary ignition components (coil, wires and plugs) – Low battery charge – Powertrain Control Module (PCM) The Error code is generally activated on detection of the following conditions: The P0321 code is triggered when the signal is out of range.
Solutions – Resecure loose wire or connectors – If battery charge is low, recharge or replaced battery – Replaced crank position sensor – Replaced starter motor
