Common Causes of P0322
Parts most likely causing this code, ranked by probability
The sensor itself has failed and is no longer sending the necessary signal to the engine computer.
80% of P0322 cases are fixed by replacing this part
Damaged, corroded, or loose wiring or a faulty connector prevents the sensor's signal from reaching the engine computer.
15% of P0322 cases are fixed by repairing wiring or connectors
The engine computer itself has an internal fault preventing it from processing the crankshaft position sensor signal.
5% of P0322 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the crankshaft position sensor's electrical connector for any looseness, corrosion, or bent pins.
- Trace the wiring harness from the sensor as far as you can, looking for any signs of damage, fraying, or cuts.
How to Diagnose P0322
- 1Visually inspect the crankshaft position sensor and its wiring harness for any obvious damage, fraying, or loose connections.
- 2Check the electrical connector at the crankshaft position sensor for corrosion or bent pins.
- 3Using a multimeter, test the crankshaft position sensor's resistance and signal output according to your vehicle's service manual specifications.
- 4Verify proper voltage supply to the crankshaft position sensor at the connector.
- 5If the sensor and wiring check out, consider testing the ECM/PCM, though this is less common.
P0322 on Popular Vehicles
Honda Accord
2003-2024Crankshaft position sensor failures are common on these models. The sensor is often located near the crankshaft pulley or behind the timing cover, which can make access challenging.
85% fixed by replacing the CKP sensor
Ford F-150
2004-2024P0322 on F-150s frequently indicates a faulty crankshaft position sensor. Sometimes, oil leaks can contaminate the sensor or its wiring, leading to premature failure.
80% fixed by replacing the CKP sensor
Chevrolet Silverado
2007-2024Silverados experiencing P0322 often have a failed crankshaft position sensor. The sensor's location can vary by engine size, but it's typically accessible from underneath the vehicle.
80% fixed by replacing the CKP sensor
Frequently Asked Questions
What does P0322 mean?
P0322 indicates that your vehicle's engine control module (ECM) is not receiving a signal from the crankshaft position sensor. This sensor is crucial for the ECM to determine engine speed and position.
Can I drive with P0322?
No, stop driving. This code means your engine may not start, or it could stall unexpectedly while you are driving, creating a dangerous situation. Immediate repair is necessary.
Will P0322 clear itself?
No, P0322 will not clear itself. This code signifies a critical sensor failure or circuit issue that prevents the engine from running correctly. The underlying problem must be fixed for the code to clear.
How do I fix P0322 myself?
Start by inspecting the crankshaft position sensor's wiring and connector for damage or looseness. If they look good, replace the crankshaft position sensor. This is often a straightforward part replacement.
How much does it cost to fix P0322?
A DIY fix for P0322 typically costs $30-$150 for the crankshaft position sensor part. Professional repair at a shop will cost $150-$400, covering the part and 1-2 hours of labor.
P0322 keeps coming back - why?
If P0322 returns after replacing the sensor, the issue is likely with the wiring harness to the sensor (a short or open circuit) or a faulty connector. Less commonly, the engine control module itself could be at fault.
Will P0322 fail emissions/smog test?
Yes, P0322 will cause your vehicle to fail an emissions or smog test. The Check Engine Light will be on, and the engine's inability to properly monitor its speed and position will prevent it from passing.
What's the difference between P0322 and P0320?
P0322 specifically means 'no signal' from the ignition/distributor engine speed input circuit, indicating a complete loss of signal. P0320 is a more general 'malfunction' in the circuit, which could mean an intermittent signal, incorrect signal, or no signal.
P0322 on Honda Accord?
On Honda Accords, P0322 often points directly to a failed crankshaft position sensor. These sensors can degrade over time due to heat and vibration. Inspect the wiring carefully, but be prepared to replace the sensor.
Questions to Ask Your Mechanic
Did you test the crankshaft position sensor's signal output with an oscilloscope?
Good answer: Yes, the sensor showed no signal or an erratic signal, confirming it's faulty. We also checked the wiring for continuity.
What did you find when inspecting the wiring harness to the crankshaft position sensor?
Good answer: We found no visible damage, corrosion, or loose connections in the wiring or connector. The circuit has proper voltage and ground.

Cost of Waiting
Ignoring P0322 means your engine will not start or will stall unexpectedly, leaving you stranded. This is not a code you can drive with.
While You're In There...
If the existing connector is corroded or damaged, replacing the pigtail ensures a solid electrical connection and prevents future issues.
Tools You'll Need
- Basic hand tools (sockets, wrenches)
- Multimeter
- Jack and jack stands (for access)
- Wire brush (for cleaning connections)
P0322 is a common sensor failure. While it's critical, replacing the crankshaft position sensor is a straightforward fix that will get your engine running reliably again.

Your Next Steps
Step 1: Perform a thorough visual inspection of the crankshaft position sensor and its wiring. Look for any obvious damage, loose connections, or corrosion at the connector.
Step 2: If the visual inspection doesn't reveal the problem, use a multimeter to test the sensor's resistance and signal output. Compare readings to your vehicle's service manual specifications.
Step 3: If the sensor tests faulty, replace the crankshaft position sensor. If the sensor tests good, focus on checking the wiring harness for continuity and shorts.
