What Does P0320 Code Mean?

What does this mean?
The Distributor/Crankshaft Position Sensor measures the exact rotational speed and position of the crankshaft. This provides a critical data signal used by the Powertrain Control Module (PCM) to control Ignition Spark Timing and Fuel Delivery. 

Code P0320 is triggered when the Distributor/Crankshaft Position Sensor signal is interrupted, unreliable or irrational.  

P0320 Symptoms

  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • Hard starting/cranking without starting
  • Engine hesitation or stalling
  • Engine dies and will not re-start

Common Problems That Trigger the P0320 Code

  • Defective Crankshaft Position Sensor
  • Faulty or corroded Crankshaft Position Sensor wiring or connections
  • Defective Camshaft Position Sensor
  • Rough running/misfiring Engine

Common Misdiagnoses

  • Crankshaft Position Sensor is replaced when the cause is a defective Camshaft Position Sensor
