P0315 2016 Chevrolet Silverado Code - Crankshaft Position System Variation Not Learned
Quick Answer
The Crankshaft Position (CKP) system variation learns feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the CKP sensor. Common causes include Crankshaft Position (CKP) system variation learning, Faulty Crankshaft Position, Crankshaft Position sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0315 2016 Chevrolet Silverado Description
The CKP system variation compensating values are stored in ECM memory after a learning procedure has been performed and the ignition switch is turned to the OFF position for at least 30 seconds. If the actual CKP variation is not within the CKP system variation compensating values stored in the ECM, DTC P0300 may be set.
If the CKP system variation values are not stored in the ECM memory or a proper ECM power-down does not occur after completing the CKP Learn Procedure, DTC P0315 sets.
What are the Possible Causes of the DTC P0315 2016 Chevrolet Silverado?
- Crankshaft Position (CKP) system variation learning
- Faulty Crankshaft Position
- Crankshaft Position sensor harness is open or shorted
- Crankshaft Position sensor circuit poor electrical connection
How to Fix the DTC P0315 2016 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
1. Turn off all the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes.
2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature.
3. Cruise at 55 mph for another 5-6 minutes.
4. Decelerate to 45 mph without braking and maintain 45 mph for 1 minute.
5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.
6. Accelerate to 55 mph and cruise for 2 minutes.
7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0315 2016 Chevrolet Silverado code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0315 2016 Chevrolet Silverado Code
What does the OBDII code P0315 mean on a 2016 Chevrolet Silverado?
The P0315 code indicates that the crankshaft position system variation has not been learned, meaning the engine control module (ECM) cannot accurately determine crankshaft position.
What are the symptoms of code P0315 in a 2016 Chevrolet Silverado?
Common symptoms include an illuminated check engine light, rough idling, engine hesitation, or reduced performance, though some vehicles may show no noticeable symptoms.
What causes the P0315 code in a 2016 Chevrolet Silverado?
Possible causes include a recently replaced crankshaft position sensor, a new ECM, a disconnected or dead battery, misaligned timing components, or wiring issues in the crankshaft position system.
Can I drive my 2016 Chevrolet Silverado with the P0315 code?
While the vehicle may still be drivable, ignoring the code could lead to worsening engine performance and potential long-term damage. It's best to address the issue promptly.
How do I fix the P0315 code on my 2016 Chevrolet Silverado?
The most common fix is performing a crankshaft position variation relearn procedure using a scan tool. If the issue persists, check the crankshaft position sensor, wiring, and ECM for faults.
Do I need special tools to fix the P0315 code on my Silverado?
Yes, performing the crankshaft variation relearn procedure requires a professional-grade scan tool capable of initiating the relearn process.
Why would a crankshaft position variation relearn be required?
A relearn is necessary after components like the crankshaft position sensor, ECM, or timing components are replaced, or if the battery has been disconnected for an extended time.
How much does it cost to fix the P0315 code on a 2016 Chevrolet Silverado?
The cost depends on the cause. A relearn procedure typically costs $50–$150 at a repair shop, but sensor or ECM replacements could cost significantly more.
Can a dead battery cause a P0315 code in my Silverado?
Yes, a dead or disconnected battery can trigger the P0315 code because the ECM may lose its stored crankshaft position data.
What happens if I ignore the P0315 code on my 2016 Chevrolet Silverado?
Ignoring the code can lead to poor engine performance, reduced fuel efficiency, and potential damage to engine components over time.
