Depending on the car manufacturer, the P0322 code’s definition may vary. For precise code definition, consult the relevant repair manual or database. Every car is unique. Before you investigate and resolve the underlying problems that led to the diagnostic trouble codes, you must be certain that you have all the necessary repair information.
The powertrain control module (PCM) uses various engine sensors to operate the engine more effectively. These include, among many others, the camshaft position sensor (CMP) and crankshaft position sensor (CKP), which offer data on engine speed and position.
What does Code P0322 mean?
If your car shows a P0322 error code, it means “Ignition/Distributor Engine Speed Input Circuit No Signal.” When the PCM doesn’t detect a signal from the engine speed sensor, the code may be set (either the camshaft or crankshaft position sensor).
The code doesn’t denote a problem with either of the sensors. Instead, this code indicates that one of these circuits is malfunctioning.
Why does the definition refer to engine speed when one of the sensor circuits is malfunctioning? The reason is that the PCM uses the sensors to determine the engine RPM, which is why the code “engine speed input circuit no signal” is used.
The Powertrain Control Module, or PCM, receives crankshaft position or timing information from the Crankshaft Position Sensor (CKP). Usually, this data is applied to engine rpm. The PCM receives precise information about the camshaft, camshaft timing, or distributor timing from the camshaft position sensor (CMP).
The PCM will set code P0322 whenever the voltage in either of these circuits falls below a predetermined level. The only problem associated with this code is an electrical circuit fault. The manufacturer, kind of ignition/distributor/engine speed sensor, and wire colors to the sensor can all affect the troubleshooting process.
The ECM needs information from the ignition/distributor engine speed sensor on the crankshaft’s rotational speed and position. The ECM can control the timing of the ignition spark and the fuel distribution using this information.
What causes Code P0322?
The following issues will cause your car to throw up a code P0322:
- A defective crankshaft position sensor or camshaft position sensor in the engine.
- Circuit problems, including a frayed wire or a bad connection.
- Defective PCM (very rare) or outdated PCM software.
When there is an electrical circuit problem in your crankshaft and camshaft sensors, this issue code is triggered. The relative position of these two parts is closely monitored by the crankshaft position sensor (CKP) and your camshaft position sensor (CMP).
What are the Symptoms of Code P0322?
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 a 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
Steps to diagnose P0322
Stalling, misfiring, and checking engine lights are frequent problems for all cars. However, it can be challenging to isolate the problematic component because there may be several.
Leave the task to a professional if you want an accurate diagnosis.
What to avoid when checking for Code P0322
The mechanic can make unnecessary sensor replacements or repairs that won’t truly clear the error code or address the misfire issue.
How to Fix P0322 code
Accurately determining the root cause of any OBD-II code is the first step in its correction. Unfortunately, there isn’t a single remedy that works for all problems once the reason has been found.
Consulting an internet repair database or repair manual is the first step toward a potential fix.
The camshaft position sensor, crankshaft position sensor, and distributor position sensor must be repaired or replaced. Another way of fixing P0322 is getting the battery fully charged or replacing it.
Always check for technical service bulletins (TSB). This is an excellent place to start.
Find your car’s ignition, distributor, and engine speed sensor next. This could be a pick-up coil/sensor inside the distributor, a crank sensor or cam sensor, or even a coil wire connecting to the PCM to confirm the ignition system firing. Once found, visually examine the wiring and connectors.
Be looking for rubbing, scraping, bare wires, burns, or melting plastic. First, examine the connectors’ terminals (metal portions) by carefully pulling them apart. Examine them to see whether they appear scorched or if a green tint indicates corrosion. Apply electrical grease where the terminals connect and allow to dry.
Cost of repairing a P0322 issue
P0322 is “Ignition/Distributor Engine Speed Input Circuit No Signal,” a diagnostic trouble code (DTC). Numerous things can cause this. Thus, a technician must identify the precise cause in your case to clear the code.
For $120, a qualified mechanic will visit your house or business to run the check engine light diagnostic.
