Code P0016 2017 GMC Sierra Description
The P0016 code indicates that there is a discrepancy between the crankshaft position sensor and the intake camshaft position sensor in the engine. This can lead to timing issues, misfires, and poor engine performance. The Engine Control Module (ECM) uses data from both sensors to determine the optimal timing for fuel injection and ignition. When these signals do not align correctly, it can cause the engine to run inefficiently or even stall.
Common Causes of P0016 2017 GMC Sierra
- Faulty crankshaft position sensor
- Faulty intake camshaft position sensor
- Timing chain or belt issues
- Engine oil sludge or debris blocking sensors
- ECM software or hardware issues
Symptoms of P0016 2017 GMC Sierra
- Rough idling or stalling
- Decreased fuel efficiency
- Engine misfires
- Loss of power
- Illumination of the check engine light
How to Fix P0016 2017 GMC Sierra
- Perform a diagnostic scan to confirm the P0016 code and pinpoint the exact cause.
- Inspect and replace the crankshaft position sensor if faulty.
- Inspect and replace the intake camshaft position sensor if faulty.
- Check and adjust the timing chain or belt if necessary.
- Clear the code and reset the ECM to see if the issue recurs.
Cost to Fix P0016 2017 GMC Sierra

Frequently Asked Questions about P0016 2017 GMC Sierra Code
What does the OBDII code P0016 indicate on a 2017 GMC Sierra?
Code P0016 indicates a discrepancy between the readings from the crankshaft position sensor and the intake camshaft position sensor, suggesting that the positions are not aligned as expected. This misalignment can affect the engine's timing and performance.
What are common symptoms of code P0016 in a 2017 GMC Sierra?
Common symptoms include poor engine performance, rough idling, difficulty starting the engine, and possibly the engine failing to start. The Check Engine Light will also be illuminated.
What could cause the P0016 code to appear on a 2017 GMC Sierra?
Potential causes for this code can include a timing belt or chain that has slipped or is worn out, issues with the crankshaft or camshaft position sensors (such as faulty sensors or wiring problems), or the timing components may be damaged or worn.
How is the P0016 code diagnosed in a 2017 GMC Sierra?
Diagnosis typically involves verifying the code with an OBD-II scanner, inspecting the timing belt or chain for integrity and correct alignment, checking the crankshaft and camshaft position sensors for faults, and examining all related wiring and connectors for damage.
What are the potential repairs for resolving code P0016 on a 2017 GMC Sierra?
Repairs can range from replacing the crankshaft or camshaft position sensors, repairing or replacing damaged wiring, to more extensive repairs such as replacing the timing belt or chain and possibly re-timing the engine.
Is it safe to drive a 2017 GMC Sierra with the P0016 code?
Driving with the P0016 code can lead to further engine damage and potentially unsafe driving conditions. It is advisable to address the issue promptly to avoid more serious problems.
How urgent is it to fix a P0016 code on a 2017 GMC Sierra?
It is quite urgent to address this code because it relates to the engine's timing, which is crucial for proper engine operation and performance. Ignoring it could lead to engine failure.
Can a faulty battery or poor electrical connections cause the P0016 code in a 2017 GMC Sierra?
While a faulty battery itself is unlikely to cause this specific code, poor electrical connections, especially related to the crankshaft or camshaft sensors, can indeed trigger this error. Ensure all connections are secure and free of corrosion.
