P0016 on a 2022 Subaru Outback
Crank/Cam Correlation Fault (Bank 1 Intake)
P0016 on a 2022 Subaru Outback indicates crank/cam correlation fault (bank 1 intake). It usually stays drivable short-term but should be diagnosed promptly. The most common cause is stretched timing chain or worn guides (typically $800–$3,500). Confirm the root cause before replacing parts.
What does P0016 mean on a 2022 Subaru Outback?
P0016 is set when the ECM compares the relative timing of the crankshaft and Bank 1 intake camshaft sensors and finds them more than a calibrated number of degrees out of alignment. This almost always means one of three things: the timing chain or belt has stretched or jumped, the cam phaser is mechanically stuck, or one of the position sensors is producing a bad signal. P0016 is one of the strongest early indicators of timing chain wear on modern engines.
This guide covers P0016 across the 2020-2024 Subaru Outback generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2020 through 2024.
Is it safe to drive a 2022 Subaru Outback with P0016?
In most cases a 2022 Subaru Outback stays drivable for short trips with P0016 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0016 on a 2022 Subaru Outback?
- Check Engine Light is illuminated
- Hard cold start with long crank times
- Rough idle and reduced low-end torque
- Engine rattle or chirp on startup (chain slap)
- Mid-range power loss
- Reduced fuel economy
- Possible no-start if cam timing has slipped far enough
What causes P0016 on a 2022 Subaru Outback?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Stretched timing chain or worn guides Chain stretch is a well-documented failure on many 2010-2020 engines. | Most common | $800–$3,500 |
| Stuck or worn cam phaser (cannot return to base timing) | Common | $400–$1,500 |
| Failed cam or crank position sensor producing offset readings | Common | $100–$400 |
| VVT oil control valve stuck open advancing cam without command | Occasional | $100–$450 |
| Low oil pressure causing the cam phaser to drift | Occasional | $50–$200 |
| Tone ring slipped or damaged on the cam or crankshaft | Occasional | $300–$1,500 |
| Timing chain jumped one tooth after a tensioner failure | Rare | $1,000–$4,000 |
How to diagnose this on a 2022 Subaru Outback
-
Verify engine oil level and pressure first
P0016 with low oil pressure is often the VVT system unable to return the cam phaser to base position. Confirm oil level on level ground, check condition (dark or sludgy?), and measure pressure at idle and 2500 RPM before proceeding.
Tools: Dipstick, Mechanical oil pressure gauge
-
Read cam-crank correlation in live data
With the engine running, watch the cam and crank position PIDs. They should maintain a fixed offset. If the offset drifts as RPM rises, the chain is stretching under load. If the offset is static but wrong, the chain may have jumped a tooth.
Tools: Scan tool with cam and crank position PIDs
-
Listen for timing chain noise
With a stethoscope on the front timing cover, listen at cold start. A healthy chain runs silent. A rattle for 1–3 seconds at cold start that quiets with oil pressure is early chain wear. Continuous rattle at idle indicates advanced wear — at this point the chain must be replaced soon to avoid valve damage.
Tools: Mechanic's stethoscope
-
Inspect timing chain stretch directly (specific engines)
On engines with documented chain wear (BMW N20/N26, Ford 5.4 3V, VW/Audi EA888, GM 3.6 LFX/LLT), the chain wear can be measured with the front cover off. The chain mark on the head/cam sprocket relative to the manufacturer's wear indicator tells you the remaining service life.
Tools: Engine service manual, Specialized timing tools (engine-specific)
-
Test the cam and crank sensors with a scope
Both sensors should produce clean square-wave signals. Compare to known-good waveforms in the service manual. A sensor with a missing tooth or noise on the signal will set P0016 even with a perfect chain. Replacing the sensor is the cheap fix to rule out before opening the timing cover.
Tools: Oscilloscope or scan tool with raw sensor PIDs

How do I fix P0016 on a 2022 Subaru Outback?
- Full timing chain replacement (chain, guides, tensioner, sprockets)
- Replace the cam phaser / VVT actuator
- Replace the cam and / or crank position sensor
- Service the VVT oil control valve
- Correct any underlying oil pressure or level issue
About the 2020-2024 Subaru Outback
The 2020-2024 Subaru Outback was commonly sold with the following powertrains: 2.5L H4, 2.4L Turbo H4, 3.6L H6. Common trims include Base, Premium, Limited, Touring, Wilderness, Onyx Edition.
Why P0016 is a “cheap or expensive” code
P0016 has a wide repair-cost range because the root causes range from a $30 sensor to a $3,000+ timing chain replacement. Always test the cheap parts first: oil level and pressure, then the cam and crank sensors, then the VVT oil control valve, before assuming a chain job. Skipping straight to the chain wastes money about a third of the time.
P0016 on engines with chain-stretch history
A short list of engines where P0016 should be assumed to be a timing chain problem until proven otherwise:
- BMW N20 / N26 2.0T — chronic chain failure, often catastrophic
- VW / Audi 2.0 TSI EA888 Gen 1 and Gen 2 — chain stretch around 80k
- Ford 5.4 3V Triton V8 — phaser + chain failures together
- GM 3.6 LFX, LLT, LF1 — chain stretch around 80–120k
- Hyundai / Kia Theta II 2.4 — chain and tensioner failures
On these engines a P0016 with chain rattle is essentially a guaranteed chain job. Replace as a complete kit (chain, guides, tensioner, sprockets) — half-replacing leads to repeat failure.
What happens if you ignore P0016
If the underlying cause is chain stretch, the chain will eventually skip a tooth — at which point the engine will lose compression and on interference engines (most modern designs), the valves will hit the pistons. The repair bill jumps from “timing chain” ($1,500–$3,500) to “rebuilt cylinder head or new engine” ($4,000–$10,000+). P0016 on a documented chain-stretch engine should be fixed within weeks, not months.
