The OBD-II Code P0322 means that your vehicle’s powertrain control module (PCM) or engine control module (ECM) has indicated a problem with your camshaft position sensor (CMP) or crankshaft position sensor (CKP), with a specific voltage issue in one of the two circuits available.
The generic powertrain code will usually apply to all spark ignition engines that are OBD-II equipped.
What Does Code P0322 Mean?
The P0322 Code is defined as “Ignition/Distributor Engine Speed Input Circuit No Signal.”
This code is also commonly referred to as a crankshaft or camshaft position sensor error code. The Engine Control Module (ECM) has detected an issue with the the rotation speed or the position of the crankshaft or camshaft.
The ECM receives an input from the crankshaft and camshaft position sensors based on the engine configuration and the year, make and model of the vehicle. The input is used to monitor the speed and position of the crankshaft and camshaft.
Some automobiles also incorporate an ignition/distributor speed sensor that is monitored by the ECM. This information is used to adjust the ignition timing and the fuel settings to adapt to engine load variations and improve performance.
Potential Causes of a P0322 Code
Potential causes for this code to set are:
- Open in the control circuit (ground circuit) between the ignition/distributor/engine speed sensor and the PCM
- Open in the power supply circuit between the ignition/distributor/engine speed sensor and the PCM
- Short to ground in the power supply circuit to the ignition/distributor/engine speed sensor
- Ignition/distributor/engine speed sensor faulty
- Possibly a PCM has failed (highly unlikely)
What are the Common Symptoms of the P0322 Code?
The symptoms of the P0322 code are engine-related because the PCM’s ability to run the engine effectively is hampered by the absence of signal from the CKP and CMP.
The following are some of these signs:
- The engine turns over but won’t start.
- Car misfires
- No power for your car
- Stalling
- Check-engine indicator
- Increased use of fuel
How to Fix P0322 Code?
The steps to fixing OBD-II code P0322 :
- Powertrain Control Module – A failed PCM could get intermittent to a degree that your vehicle will be unable to start or it will begin to stall when running. You will begin to see that exhaust fumes have shorted while the car runs, emissions system control signals are failing, so with a PCM that’s not functioning correctly, you must immediately have it replaced.
- Battery – Cold temperatures cause the battery charge to drop, so the car will need to be revitalized to start. To keep this situation from happening again, a battery should be replaced before its volume drops to a serious level. An average car battery lasts from 5 to 7 years.
- Distributor – A distributor that isn’t working properly can cause crucial damage to the engine. Plugged up filters can result in rough idling, but it’s tough to indicate if a filter is clogged, so it’s best to have it replaced at each tune-up.
- Crankshaft Position Sensor – If the crankshaft position sensor or its wiring has any problems, it can result in a crankshaft signal disconnection while the engine is still running, which can cause the engine to stop immediately. If you conjecture that your crankshaft position sensor has a problem, have the vehicle examined by a professional mechanic.
- Engine Control Module – Your vehicle might not start even after making sure it’s evident the battery and starter are working correctly. If your car’s issues all point to a failed engine control module, it should be restored instantly to prevent further crucial risks to your vehicle.
- Camshaft Position Sensor – As the camshaft position sensor debilitates, the signal it channels to the vehicle’s ECM also weaken. Eventually, the signal will decline so much that it will switch off, and so will the engine. This can occur while the vehicle is parked, or while you are driving, so the sensor must be replaced.
