Code P0315 2016 Chevrolet Silverado Description
The P0315 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates that the crankshaft position system variation has not been learned by the engine control module (ECM). In simpler terms, this means that the ECM has not been able to properly calibrate the crankshaft position sensor, which is crucial for the engine to run smoothly and efficiently. The crankshaft position sensor detects the position of the crankshaft in relation to the engine's timing, allowing the ECM to adjust fuel injection and ignition timing accordingly.
Common Causes of P0315 2016 Chevrolet Silverado
- Faulty crankshaft position sensor
- Damaged wiring or connectors related to the sensor
- Incorrect sensor alignment with the crankshaft
- ECM software issues
- Engine mechanical problems affecting sensor readings
Symptoms of P0315 2016 Chevrolet Silverado
- Engine misfires
- Rough idling
- Stalling
- Difficulty starting the engine
- Reduced fuel efficiency
How to Fix P0315 2016 Chevrolet Silverado
- Use a diagnostic scan tool to retrieve and clear the DTC.
- Inspect the crankshaft position sensor, wiring, and connectors for any signs of damage or wear.
- Verify the alignment of the sensor with the crankshaft.
- Recalibrate the crankshaft position sensor using a professional scan tool.
- Test drive the vehicle to ensure that the code does not return and that the engine operates smoothly.
Cost to Fix P0315 2016 Chevrolet Silverado
The typical repair costs for addressing a P0315 code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, replacing a faulty crankshaft position sensor can cost between $100 and $200, including parts and labor. However, if additional repairs or diagnostic work are needed, the total cost may increase. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that labor rates and part prices can vary based on location, vehicle make and model, and other factors.
Tech Notes for P0315 2016 Chevrolet Silverado
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.

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.
