This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer isn't getting a signal from the part that tells it how fast the engine is spinning. It's like trying to ride a bike without knowing how fast you're going.
The engine control module (ECM) is not receiving a signal from the ignition/distributor engine speed sensor.
The P0322 code is triggered when the ECM detects no signal from the ignition/distributor engine speed sensor. This sensor provides critical data about engine speed and timing, which is essential for proper engine operation. Without this information, the ECM cannot accurately control fuel injection and ignition timing.
• Engine may not start
• Engine misfires
• Check Engine Light is on
• Faulty ignition/distributor engine speed sensor
• Damaged or corroded wiring or connectors
• Faulty ECM
ECM: Engine Control Module, the computer that manages engine functions.
Distributor: A component in older ignition systems that routes high voltage from the ignition coil to the spark plugs.
• Check for any additional codes
• Inspect the wiring and connectors to the sensor
• Test the ignition/distributor engine speed sensor
• Replace the faulty sensor
• Repair or replace damaged wiring or connectors
• Replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Volkswagen Jetta
• Ford Focus
• Chevrolet Malibu
• Regularly inspect and maintain engine sensors
• Ensure wiring and connectors are free from corrosion
• Perform routine diagnostic checks
Sensor Issue
• Do not ignore the Check Engine Light
• Have the vehicle diagnosed by a professional
• Avoid driving the vehicle if it exhibits severe symptoms
Check with the vehicle manufacturer for sensor warranty coverage.
This code has been commonly reported in vehicles with older ignition systems that use distributors.
Moderate – The vehicle may still be drivable, but it could lead to further issues if not addressed.
Driving with a faulty ignition system can lead to increased emissions and potential safety hazards.
• Engine at operating temperature
• Vehicle stationary or during a road test
The ignition/distributor engine speed sensor is typically located near the crankshaft or within the distributor assembly.
Q: Can I drive with a P0322 code?
A: It's not recommended as it can lead to further engine issues and unreliable vehicle performance.
Q: How do I reset the Check Engine Light after fixing P0322?
A: Use an OBD-II scanner to clear the code after repairs are completed.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
