P016F
Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A Range/PerformanceP016F is a generic OBD-II powertrain diagnostic trouble code: Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A Range/Performance. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.
What P016F means
P016F is the Bank 2 intake camshaft range/performance correlation code, the Bank 2 counterpart to P016E. The PCM has detected that the Bank 2 intake cam position is erratic or outside the performance specification relative to the crankshaft during dynamic engine operation, rather than being simply stuck at a wrong position.
On V-engines, Bank 2 phasers and their oil circuits can behave differently from Bank 1 due to differences in oil gallery routing, chain run length, and proximity to the oil pump. A range/performance fault on Bank 2 alone can indicate a Bank 2 specific oil supply restriction, a phaser with partial internal wear, or a lash adjuster issue affecting cam lobe contact without triggering a full stall of the phaser.
As with all cam correlation range/performance codes, thorough live data analysis across operating conditions is more useful than static testing at idle. The technician should pay particular attention to behavior during warm-up, during rapid throttle changes, and at sustained high engine loads.
Common causes
Most-frequently reported root causes when P016F is logged.
-
1
Bank 2 intake phaser that is partially worn, producing erratic movement.
-
2
Bank 2 OCV with inconsistent response due to contamination or wear.
-
3
Oil pressure drop specific to Bank 2 gallery routing under load.
-
4
Stretched Bank 2 timing chain segment with variable slack at different RPMs.
-
5
Intermittent Bank 2 intake CMP sensor signal fault.
-
6
Loose or cracked timing chain guide on the Bank 2 intake cam run.
-
7
VVT system hydraulic response affected by oil aeration or foam.

How to diagnose P016F
A typical diagnostic flow when this code is present.
-
1
Scan for all DTCs and note if Bank 1 cam or chain codes are also present.
-
2
Review freeze-frame data to determine load, RPM, and temperature conditions at fault set.
-
3
Verify oil level and pressure; oil pressure issues are amplified at high load when phasers need the most flow.
-
4
Observe Bank 2 intake cam actual versus desired on live data during a test drive.
-
5
Inspect and functionally test the Bank 2 intake OCV; check the filter screen for debris.
-
6
If OCV is good, inspect timing chain for uneven wear or guide damage.
-
7
Repair the identified component and retest under conditions that previously triggered the fault.

Frequently asked questions
Can P016F appear if only one phaser vane seal is worn?
Yes. A worn vane seal in the phaser can cause the actuator to bleed down and hunt for position, producing exactly the erratic behavior associated with a range/performance code.
Should I replace the phaser or OCV first?
Always test the OCV first since it is less expensive and more accessible. Only replace the phaser if the OCV tests good and the fault persists.
Is Bank 2 the same side on all engines?
No. Bank 2 identification depends on the engine configuration. Always confirm which bank is Bank 2 for the specific vehicle before starting component replacement.
Can synthetic oil help with P016F?
Using the manufacturer-specified viscosity synthetic oil can improve phaser response, especially in cold conditions, but it will not compensate for a mechanically worn phaser or OCV.
Disabling P016F in software
RaceTune can permanently disable P016F — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.
Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
