Code P0016 GMC Description
The P0016 diagnostic trouble code (DTC) for GMC vehicles indicates a problem with the correlation between the crankshaft position sensor and the intake camshaft position sensor. This means that the Engine Control Module (ECM) has detected that the positions of the crankshaft and intake camshaft are not in sync as they should be. This issue can lead to poor engine performance, misfires, and potentially even engine damage if not addressed promptly.
Common Causes of P0016 GMC
- Faulty crankshaft position sensor
- Faulty intake camshaft position sensor
- Timing chain or belt issues
- Engine mechanical problems
- Wiring or connector issues
Symptoms of P0016 GMC
- Rough idle
- Engine misfires
- Decreased fuel efficiency
- Stalling
- Check engine light illuminated
How to Fix P0016 GMC
- Diagnose the issue using a scan tool to confirm the P0016 code and pinpoint the source of the problem.
- Inspect the crankshaft position sensor and intake camshaft position sensor for any damage or malfunction.
- Check the timing chain or belt for proper alignment and tension.
- Inspect the engine for any mechanical issues that could be causing the correlation problem.
- Replace any faulty sensors, repair wiring or connectors, and adjust the timing chain or belt as needed.
Cost to Fix P0016 GMC
The typical repair costs for addressing a P0016 code can range from $200 to $500, depending on the specific cause of the issue and the labor rates at the auto repair shop. It's important to note that additional costs may be incurred if other related components need to be replaced or repaired.

If this Diagnostic Trouble Code (DTC) started after recent internal engine repairs, inspect for proper engine mechanical timing. With the camshaft cover removed and the #1 cylinder at top dead center, make sure that the darkened chain links are lined up with the alignment marks on the exhaust and intake cam sprockets.
If a P0016 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.

Discuss the causes and fixes for P0016 GMC OBDII Code
-
I changed the cam and crank sensor on my 2007 yukon went to relearn crank sensor and code p0016 came right back one mech. Said his tech 2 says ign. Or injector fault but with live data saw any misses
-
How is the engine oil level and condition? how often do you change the engine oil? dirty or low engine oil could cause this problem.
-
Low or dirty oil can cause an improper operation of the cam phaser, which is what advance or retard the engine timing during certain engine operation.
-
on my 2007 yukon, i have the same problem, i changed the cam and crank senor, changed the oil pressure sensor because it was reading low oil everytime it idle. and the check engine still came on, i changed the oil. and nothing what else could be the problem?
